Product Overview

IS220PAOCH1B is an analog‑output I/O pack for GE Mark VIe distributed‑I/O control‑platform. It converts controller‑set‑point digital‑values into stable 4‑20 mA or ±10 V analog‑output signals to drive field‑positioners, valve‑actuators and remote‑process‑control‑devices. Dual‑port redundant IONet Ethernet links realise high‑availability network‑communication with Mark VIe main‑controller. Open‑loop‑circuit diagnostic‑function detects broken field‑wiring for improved fault‑troubleshooting efficiency. Widely used for turbine auxiliary‑process‑loop‑control and plant‑remote‑actuator‑command‑output. Discontinued automation spare‑component available as refurbished and surplus tested hardware for legacy power‑plant‑control‑cabinet repair‑projects.

Application Notes

‑ Install onto matching PAOC‑series terminal‑base assembly; enforce ESD anti‑static handling. ‑ Use shielded twisted‑pair wiring for all analog‑output field‑loops. ‑ Select output‑signal‑range for each channel within ToolboxST software. ‑ Typical deployment: power‑plant Mark VIe analog‑output‑I/O‑pack spare‑part stocking.
