IS200SRLYH2A GE DO Plug Box Type TB

Description:

IS200SRLYH2A is a Simplex Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE distributed turbine control systems. The Simplex Relay Output (SRLY) terminal board is a simplex S-type terminal board that accepts a PDOA/YDOA I/O pack and offers 48 customer terminals for 12 form C relay output circuits. The physical dimensions, customer terminal placements, and I/O pack mounting of SRLY are identical to those of other S-type terminal boards. A connected PDOA or YDOA I/O pack will be the highest component, allowing for double stacking of terminal boards. Each relay on SRLY feeds PDOA and YDOA its position using a single, isolated contact pair.

INSTALLATION:

A sheet metal carrier with SRLY and a plastic insulator installed on it is fastened to a cabinet with screws. Option boards can be plugged into SRLYH2A or SRLYS2A and are held in place by the connectors' force. The purpose of each terminal point in relation to the existence of an option board is described in the following table.
