The Yokogawa PS11*C, also cataloged as the PS11 CPU Module, operates as a dedicated hardware component for central processing and logic execution within Yokogawa distributed control system platforms.
| Parameter | Specification |
|---|---|
| Model | PS11*C |
| Brand | Yokogawa |
| Origin | USA |
| Weight | 1 kg |
| Dimensions | 25.4 cm x 7.6 cm x 20.3 cm |
| Operating Temp | 0 to 60 deg C |
| Power Consumption | 15 W (typical) |
| Processor Type | Proprietary RISC architecture |
| Backplane Interface | Dedicated high-speed bus |
The module integrates advanced algorithms to manage 4-20 mA HART loop protocol communications across the field network. By facilitating channel-to-channel isolation, the PS11*C ensures signal integrity during high-speed data acquisition. Cold junction compensation (CJC) is managed via integrated circuitry to minimize thermal drift in analog thermocouple inputs, maintaining loop accuracy within industrial process control environments.
Q: Is the PS11*C module capable of hot-swapping during active system operation?
A: No. Power must be removed from the local segment before the module is extracted or inserted into the backplane to prevent electrical arcing and data bus corruption.
Q: What is the maximum cycle time supported by the PS11*C processor?
A: The processor cycle time is dependent on the configured scan rate of the I/O rack. Under standard loading, typical scan intervals are maintained at 50 ms to 100 ms.
