GE IS410SRLYS2A Simplex Relay Output Terminal Board

Product Description

The GE IS410SRLYS2A is a simplex S-type relay output terminal board designed for GE Speedtronic Mark VIe / Mark VIeS functional safety systems. It works together with IS420YDOAS1B I/O pack, providing 12 Form-C dry contact relay output channels for safety interlock and discrete switching control. Optional WRO wetting daughterboards can be installed for loop monitoring and contact wetting. It is widely used in turbine safety control cabinets and is a critical spare part for power plant and oil & gas safety system maintenance and retrofit.
