About the IS220PDIOH1A

The IS220PDIOH1A is an I/O pack module for a Mark VIe Speedtronic system.  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. 

The IS220PDIOH1A has two Ethernet ports and its own local processor.  It can be used in conjunction with terminal boards IS200TDBSH2A and IS200TDBTH2A.   These I/O pack/terminal board combinations have been approved for use in hazardous locations.  

The IS220PDIOH1A has a minimum voltage rating of 27.4 VDC.  Its 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.  This information can be found within GE manuals relating to this unit, such as GEH-6725. 

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. 

For more information about this I/O module or about associated terminal boards, please refer to the original documentation from General Electric.  Manuals, data sheets, and user guides will provide detailed specifications about installation, maintenance, and handling that should be reviewed before unboxing your part from AX Control.
