Functional Overview of the IS220PAOCH1B Pack

• The IS220PAOCH1B acts as the electrical interface between the I/O network and analog terminal board.
• It uses a common processor board and a dedicated analog output acquisition board pair.
• Each output uses a 16-bit DAC to drive an external transistor amplifier for precise regulation.
• An internal temperature sensor monitors board temperature and alerts the control system.
• Mechanical normally-open relays enable or disable each output for added safety.
• Current feedback comes from a 16-bit ADC measuring across a 50-ohm resistor on the terminal board.

Compatibility and Control Modes for GE IS220PAOCH1B

• Simplex: Uses one I/O pack with one or two Ethernet ports – cost-effective for non-critical tasks.
• Dual: Two parallel packs with up to two Ethernet connections each – provides automatic failover.
• TMR (Triple Modular Redundant): Three packs with dedicated networks – 2-out-of-3 voting for highest integrity.
• The PAOCH1B is compatible with terminal board TBAOH1C and STAO board (not DTAO DIN-rail).
