Energy saving

	Auto-light function
	Display brightness is controlled after measurement from the front light sensor. This saves energy when connecting multiple units.

	Display-off function
	Displays are turned off when operation does not occur for the time set during Indication time setting. PV, SV or no indication is selectable during Display selection mode by keypad.

I/O for each channel is individually selectable

	Input
	Individually selectable from thermocouple, RTD, DC current, DC voltage for each channel. Also infrared thermocouples (RD-300 series, RD-401) are usable. (e.g.) CH1 input: Thermocouple CH2 input: DC voltage

	Output
	Selectable from Relay contact, Non-contact voltage and DC current output. (e.g.) CH1 control output: Relay contact output CH2 control output: DC current output

Input sampling period selectable

Select from a choice of: 25ms, 125ms, 250ms via keypad.
High accuracy control can be performed by selecting optimal sampling period.

Block function provided via console software

Block function can be used through console software.
For each channel, Input block, Control block and Output block can be freely selected and combined.
Customizable specifications for various usages.

Initial selection status

	Input 1 block function
	PV difference input [Input 1 block] receives (Input 1 - Input 2) or (Input 2 - Input 1), then outputs to [Control 1 block]. PV addition input [Input 1 block] receives (Input 1 + Input 2), then outputs to [Control 1 block].
	Input 2 block function
	PV difference input [Input 2 block] receives (Input 1 - Input 2) or (Input 2 - Input 1) , then outputs to [Control 2 block]. PV addition input [Input 2 block] receives (Input 1 + Input 2), then outputs to [Control 2 block].
	Control 1 block, Control 2 block function
	Heating/Cooling control output Heating/Cooling control computation is carried out in [Control 1 block], then outputs from [Output 1 block] to [Output 1 (Heating)] and [Output 2 (Cooling)]. External setting input (Remote) [Input 2] receives External input. Control computation is carried out using [Control 1 block] value received from [Input 2 block] output, then outputs from [Output 1 block] to [Output 1]. Cascade control CH2 is a master (1st-order controller), and CH1 is a slave (2nd-order controller). Control computation is carried out at [Control 2 block] of the master (1st-order controller). Its output will become the set value of [Control 1 block] of the slave (2nd-order controller), and control computation is carried out using this value, then outputs from [Output 1 block] to [Output 1].
	Output 1 block function
	Output 2 output [Output 1 block] receives [Control 1 block] output, and outputs to [Output 2]. 1-input, 2-outputs [Output 1 block] receives [Control 1 block] output, and outputs to [Output1] and [Output 2].
	Output 2 block function
	Transmission output Selects the PV, SV or MV via Console software or keypad operation, and outputs from [Output 2 block] to [Output 2].

In addition to the above, the following functions can be used.
-Reading and setting of SV, PID and various set values.

SV ramp function

When the SV is adjusted, it approaches the new SV by the preset rate-of-change (

/min,

/min)
When the power is turned on, the control starts from the PV and approaches the SV by the rate-of-change.

Auto/Manual control switching

Auto/Manual control can be switched by keypad.
If control action is switched from automatic to manual and vice versa, balanceless-bumpless function works to prevent sudden MV change.
If control action is switched to manual, the manual MV is indicated on the display. (CHx display flashes.)
When power is turned on, control action starts from its previous controller status (last shutdown).

Timer spec

Selects either Control timer or Delay timer function.
-Control timer:
Timer starts when CH1 input exceeds Control timer start temperature.
After Control timer setting time has elapsed, control (for DC current output, output low limit) and alarm action will stop.
-Delay timer:
When DI input is ON (Closed), the timer starts.
Timer output turns ON after ON delay timer time has passed.
Timer output turns OFF after OFF delay timer time has passed.

Cascade control
(Block function)

To control one process, 2 inputs [CH2 as a master (1st-order controller), and CH1 as a slave (2nd-order controller)] are used for more advanced control.
MV is calculated from PV and SV of the master (CH2), and is used as SV of the slave (CH1), with which CH1 control computation is carried out, then outputs from CH1 control output.
[CH2 control output will be OFF (0mA for DC current output) or OUT2 (Cooling output) for Heating/Cooling control.]
MV (0 to 100%) of the master (CH2) corresponds to the SV (External setting low limit to External setting high limit) of the slave (CH1).

Heating/Cooling control output (Block function)

This is 1ch Heating/Cooling control output spec. CH1 will be Heating output (OUT1) and CH2 will be Cooling output (OUT2), followed by control performance.

OUT2 proportional band (P)	0.0 to 10.0 times OUT1 proportional band (ON/OFF control when set to 0.0.)
Integral time (I)	Same as that of OUT1
Derivative time (D)	Same as that of OUT1
OUT2 proportional cycle	1 to 120sec
ARW	Same as that of OUT1
Overlap/Dead band	Thermocouple, RTD input: -100.0 to 100.0 () DC current, voltage input: -1000 to 1000
OUT2 ON/OFF hysteresis	0.1 to 100.0 () (DC current, voltage input: 1 to 1000)
OUT2 high limit, OUT2 low limit	0 to 100% (DC current output: -5 to 105%)
OUT2 action mode	Air cooling (linear characteristic), Oil cooling (1.5th power of the linear characteristic), Water cooling (2nd power of the linear characteristic)

Non-contact voltage (for SSR drive)	12V DC15%, Max 40mA DC (short circuit protected)
DC current	4 to 20mA DC, Load resistance: Max 600

External setting input
(Block function)

External analog signal will become the SV.
Control desired value (SV) adds remote bias value to the External setting input value.
As a setting signal, specify any DC range during input type selection via console software.

Setting signal	DC current: 4 to 20mA or 0 to 20mA DC DC voltage: 1 to 5V or 0 to 1V DC
Allowable input	DC current: 50mA DC or less DC voltage (0 to 1V): 5V DC or less DC voltage (1 to 5V): 10V DC or less
Input impedance	DC current: 50 [Externally connect a shunt resistor (sold separately).] DC voltage: 100k
Input sampling period	Depends on Input sampling period selection.

Transmission output (Block function)

Converting any value (PV, SV or MV) to analog signal every input sampling period, outputs the value in current.
To use Transmission output, specify 'Current' for CH2 control output.

Resolution	1/10000
Current	4 to 20mA DC (load resistance Max 550)
Output accuracy	Within 0.3% of Transmission output span

CH1 PV difference (CH1-CH2) input
(Block function)

Temperature difference between CH1 and CH2 (CH1-CH2) will be the input value for CH1, and control is performed using this value.
PV = (CH1 PV - CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel.

CH1 PV addition (CH1+CH2) input
(Block function)

Addition value of CH1 and CH2 will be the input value for CH1, and control is performed using this value.
PV = (CH1 PV + CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and addition depend on the reference channel.

CH2 PV difference (CH2-CH1) input
(Block function)

Temperature difference between CH1 and CH2 (CH2-CH1) will be the input value for CH2, and control for CH2 is performed using this value.
PV = (CH2PV - CH1PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel.

CH2 PV addition (CH1+CH2) input
(Block function)

Addition value of CH1 and CH2 will be the input value for CH2, and control is performed using this value.
PV = (CH1 PV + CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and addition depend on the reference channel.
