IS220PDIIH1B 336A5026ADP1 GE Mark VIe Isolated Discrete Input Pack
Product Overview
IS220PDIIH1B, board part number 336A5026ADP1, is an isolated discrete input I/O pack for the GE Speedtronic Mark VIe turbine control system. It is the upgraded B-series replacement for legacy IS220PDIIH1A. This PDII pack collects digital status signals from field switches, emergency stop contacts, valve position feedback and relay contacts, featuring full galvanic isolation per channel to block high voltage noise and ground loop interference. It communicates with Mark VIe controllers over redundant IONET dual Ethernet links, supports hot swap, simplex and TMR triple redundant configurations for gas & steam turbine safety protection loops in power plants.

FAQ
Q1: What is 336A5026ADP1?
A: 336A5026ADP1 is the internal PCB board number of IS220PDIIH1B Mark VIe isolated discrete input pack. Both numbers refer to the same I/O module.
Q2: How many isolated input channels on IS220PDIIH1B?
A: It has 16 galvanically isolated discrete input channels, different from the 24-channel non-isolated DI pack IS220PDIAH1A.
Q3: Can replace IS220PDIIH1A?
A: Yes, IS220PDIIH1B is the B-version upgraded successor of IS220PDIIH1A, backward compatible for Mark VIe system retrofit.
Q4: What condition of IS220PDIIH1B do you supply?
A: We provide fully tested surplus / refurbished IS220PDIIH1B modules. Every unit undergoes complete functional testing before shipment. Contact us for stock availability and lead time.
