IS220PDIOH1B GE

The IS220PDIOH1B unit is a discrete I/O pack that is part of the GE Speedtronic MKVIe gas turbine control modules with accessory combinations that are approved for use in hazardous locations. The Mark VIe is one of the later systems released by General Electric under the Speedtronic name. Speedtronic systems have been used for industrial turbine control since the late 1960s when General Electric released the Mark I.

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 The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete.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 IS220PDIOH1A includes LED indicators for both ethernet ports, for the unit’s power, as well as an “attn” LED. Additional LEDs are related to relay connections.

The IS220PDIOH1B has a minimum voltage rating of 27.4 VDC while the nominal rating is 28.0 VDC. The unit and its associated terminal boards have specific field wiring connection instructions that must be followed, including wire size and screw torque.
