Features:
- Bridge Between I/O Ethernet Networks and Analog Output Terminal Boards
- Merges BPPB Processor Control with Dedicated Analog Output Acquisition Circuitry
- Functions Alongside TBAOH1C and STAOH1A/H2A Terminal Boards in Mark VIe Systems
Seamless network integration is standard with the IS220PAOCH1A, and using dual Ethernet connections allows redundant communication paths to maintain control integrity in the event of a single network failure. The IS220PAOCH1A has been designed specifically for the analog output function within the PAOC I/O pack family, incorporating tailored signal conditioning and feedback monitoring capabilities within the Mark VIe architecture.
The IS220PAOCH1A provides essential analog output functions common to turbine control applications, and is a critical component of the control signal path, directly affecting the proper, normal operation of valve positioning, actuator control, and other current-loop driven devices. One or two IS220PAOCH1A I/O packs are deployed per terminal board depending on the required output channel count and system configuration. The IS220PAOCH1A occupies a compact I/O pack form factor and is always mounted directly onto its companion terminal board via the DC-37 pin connector.
For expanded output channel applications, the Mark VIe system allows multiple IS220PAOCH1A modules to be deployed across compatible terminal boards. In addition to standard single-network operation, the dual Ethernet configuration also performs automatic failover. The IS220PAOCH1A dual network configuration executes communication redundancy using the dual RJ-45 Ethernet ports specified in the module design.
The IS220PAOCH1A General Electric Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
