| PCA1 |
|
| Program capacity with 16-patterns, 16-steps
|
|
Program capacity: 16-patterns, 16-steps
Program control of up to 256 steps is possible by linking patterns. |
|
| Easily legible LCD display with 11-segment characters
|
| 11-segment character LCD display is used, so characters can be read easily. |
|
Industry-leading premium display
PV Display: 24.0 x 11.0 mm (H x W)

PV color changes linked with alarm
PV color changes: Orange, Green, Red, When any alarm is ON: Green --> Red, When any alarm is ON: Orange --> Red, or PV color changes by deviation between PV and SV.
Errors can be also checked via action indicators. |
 |
Backlight indication time
By setting backlight time (from no operation status until backlight is switched off), displays can be turned off, resulting in energy savings. |
|
| Efficient Console software
|
Console software (SWC-PCA101M) is available for data monitoring, editing, loading, etc.
Power to the PCA1 is not required if USB communication cable (CMB-001) is used. |
|
| Easy-viewing data via Monitoring software |
| By using the Monitoring software (SWM-PCA101M), setting item change, data logging and monitoring can be carried out on a PC. |
|
| Enhanced serial communication function |
| Communication protocol: Shinko protocol, Modbus ASCII , and Modbus RTU
Modbus ASCII, Modbus RTU: A maximum of 100 pieces of multiple data Read/Write is possible. |
|
| Drip-proof/Dust-proof structure
|
| IP66 (for front panel only), usable in harsh environments where dust is present or water splashes. |
