| Digital Temperature Indicating Controllers |
|
| BCS3 |
|
The BCS3 is a new basic model that compactly combines all the functions required for a temperature controller.
- Simple Design for Easy Operation Settings
- Compact Design Packed with Features
|
|
| High-visibility characters (H12 x W6mm) |
We are enhancing visibility by increasing the display font size.
|
 |
| Easy-to-Operate Key Switch Design |
We have achieved a design that emphasizes the placement of keys and ease of pressing. By simplifying the setup options, it becomes easy to change settings quickly.
1 When selecting model MOO, it corresponds to thermocouples (K, J), while selecting MOl corresponds to thermocouples |
 |
| Thermocouples(K,J),RTD(Pt100) Multi-Input or Thermocouples (R,S,T) Multi-Input |
Thermocouples are used in various applications, including industrial uses, because they exhibit stable performance even in high and low temperature environments. BCS3 is a basic model that supports five types of thermocouples: K, J, R, S, and T(*1)
(*1) When selecting model MOO, it corresponds to thermocouples (K, J), while selecting MOl corresponds to thermocouples

| Relay Contact or Non-Contact Voltage Output |
| ou can choose between control outputs: relay outputs with contact points and non-contact voltage outputs for SSR driving. Please specify your preference when placing your order according to your application. |
|
| By adding an option, you can use up to a total of 2 event outputs. |

| Control Action |
PID control (with Auto-Tuning Function)
Pl control: When Derivative Time Setting is Set to 0
PD control (with Auto-Reset Function): When Integral Time Setting is Set to 0
P control(with Auto-Reset Function): When Both Integral Time and Derivative Time Settings are Set to 0
ON/OFF control: When Proportional Band Setting is Set to 0
| Proportional Band (P) |
0 to 1000 or 2000 (Factory default at 10).
Setting it to 0 activates ON/OFF control.
If the input includes decimals, the range is 0.0 to 999.9 or 0.0 to 999.9.
Setting it to 0.0 also activates ON/OFF control. |
| Integral time(I) |
0 to 1000 seconds(Setting it to 0 disables integral action)(Factory default: 200 seconds). |
| Derivative time(D) |
0 to 300 seconds(Setting it to 0 disables derivative action)(Factory default: 50 seconds). |
| OUT proportional cycle |
1 to 120 seconds(Factory default: 30 sec for Relay contact. 3 sec for non-contact voltage). |
| ON/OFF hysteresis |
0.1 to 100.0 ()(Factory default: 1.0). |
| Output high limit, low limit |
0 to 100 %(Not applicable during ON/OFF control) (Factory defaults: Output low limit 0%, Output high limit 100%). |
