 JCx-33A --> BCx2 Replacement |
|
| Convenient Initial setting mode!
|
| This function can be used when usual AT cannot be performed normally due to temperature fluctuations. PID parameters can be calculated only when the temperature is rising.
|
'AT on startup' action
(1) Calculates AT (from startup, until PV is stabilized at SV)
(2) PID constants calculated
(3) Controls with PID constants set by the 'AT on startup'.
|
| Simplified Program control! |
The 9-step pattern is a standard feature.
Time signal output and Pattern end output can be selected in [Event output allocation].
-Number of patterns: 1
-Number of steps: 9
-Step SV: Scaling low limit value to Scaling high limit value
-Step time: 00:00 to 99:59 (Unit: Hours:Minutes, Minutes:Seconds)
-Wait value: 0 to Converted value of 20% of input span (or scaling span)
-Power restore action: Stop/Continue/Suspend (on hold)
-Program control start type: PV start/PVR start/SV start
-Number of repetitions: 0 to 10,000 |
Program pattern example
 |
| Simplified converter function!
|
For DC current output type, the controller can be used as a converter.
Input signal is converted to insulated 4 to 20 mA DC, and outputted at the converted value. |
|
| A variety of Event Input/Output functions! |
A maximum of 2 points of Event input (optional), and 2 points of Event output (1 point is standard).
Selectable from various Input/Output choices: Alarm output, Heater burnout alarm output (optional), Loop break alarm output, Time signal output, Pattern end output, etc. |
|
| Large, Easy-to-view, 5-digit PV, SV Displays! |
Large, easy-to-view, 5-digit PV, SV Displays, useful for indicating a wide range of measurement ranges.

 |
| Compact, 60 mm-deep control panel interior! |
With a depth of only 60 mm, the BCx2 series is ideal for mounting in nearly any control panel situation.
-BCD2: Depth of control panel interior 60 mm
-JCD-33A: Needs a control panel interior of 98.5 mm |
Comparing BCD2 and JCD-33A
 |
| Simple settings from a PC |
| By connecting the BCx2 to a PC using the tool cable (sold separately), and by using dedicated software, various settings can be carried out. Wiring of BCx2 is not necessary as power to the BCx2 is supplied by PC via USB. |
|
| Drip-proof/Dust-proof IP 66 |
|
IP66 structure (for the front panel) allows usage in harsh environments where the controller is exposed to water or dust. |

| Model |
| (*1): |
Thermocouple, RTD, Direct current or DC voltage are selectable by keypad. |
| (*2): |
Only one option can be selected from Option 1 and Option 2 respectively. |
| (*3): |
Event output EV1 is standard.
The following outputs can be selected in [Event output EV1/EV2 allocation] by keypad:
Alarm output (12 alarm types and No alarm action), Heater burnout alarm output, Loop break alarm output, Time signal output, Output during AT, Pattern end output, Output by communication command, Heating/Cooling control output OUT2 (for EV2 option only)
For Event output EV1/EV2, Heater burnout alarm output and Output by communication command are available when C5W, EIW, C5 or W option is ordered. |
| (*4): |
This option can be added to the BCR2, BCD2 only. If EV2+Dx and EIT options are ordered simultaneously, Transmission output is not available since EV2 output utilizes transmission output terminals. |
| (*5): |
For the BCS2, 2 points of Event input are not available. |
| (*6): |
For Direct current output type, Heater burnout alarm does not work. CT is sold separately. |
| (*7): |
For the BCS2, 1 point of Event input is available. |
