PRODUCT INFORMATION
Product Overview
The General Electric IS220PDOAH1B is a Discrete Output Module designed for Mark VI and Mark VIe systems. This module operates as an electrical interface between one or two I/O Ethernet networks and terminal boards. It features an internal BPPC processor board and an application-specific discrete output data acquisition board. The pack requires an external power input of 28 V dc during regular operation.
The IS220PDOAH1B controls up to 12 relays and accepts specific diagnostic feedback from connected terminal boards. It supports both simplex configurations and Triple Modular Redundant (TMR) architectures across discrete control loops. Compatible terminal boards include the TRLY, SRLY, WROB, WROF, WROG, and WROH designs. Depending on the connected board, the module operates electromagnetic relays or solid-state relays. The unit features a vented chassis construction for convective thermal dissipation.
