Product Description

The IS220PDIOH1B unit is a Discrete I/O Pack part of the General Electric Speedtronic Mark VI/VIe/VIeS 

gas turbine control modules with accessory combinations approved for use in hazardous locations.

When the IS220PDIOH1B model is being operated in the chosen system, it is used with several terminal

boards; some of the terminal boards used are labeled as follows:

• ISx0yTDBSH2A
• ISx0yTDBSH8A
• ISx0yTDBTH2A
• ISx0yTDBTH8A

These terminal boards extend the PDIO packs functionality, as the previous PDIO pack can only work with

two accessory terminal boards. The terminal boards are labeled as Intrinsically Safe Apparatus Relay Contact terminal boards.

This unit contains two Ethernet ports, a local processor, and a data acquisition board for use within the GE

Mark VI Speedtronic Series. The electronics technology for the Mark VIe I/O packs introduced in 2004 is

obsolete. The front panel of the IS220PDIOH1B includes LED indicators for both ethernet ports

for the unit’s power and an “attn” LED. Additional LEDs are related to relay connections.
