GE IS200TRLYS1BGG Mark VIeS Relay Output Terminal Board

IS200TRLYS1BGG connects the YDOA discrete-output interface to twelve relay circuits. Its TRLYS1B design provides coil sensing and Form-C contacts, with output wiring selected for the installed application.

IS200TRLYS1BGG provides six relay circuits that can operate as dry contacts or supply field solenoids. Powered operation requires the corresponding supply, fuses and jumpers; the remaining outputs have separate circuit roles.

IS200TRLYS1BGG supports simplex and TMR arrangements with the documented YDOA interface. Simplex uses JA1, while TMR uses JR1, JS1 and JT1; the selected pack and system configuration must agree.

IS200TRLYS1BGG has two terminal blocks with twenty-four terminals each. GE specifies conductors up to #12 AWG, with the adjacent grounded shield strip used for the field-cable shields.

IS200TRLYS1BGG is the TRLYS1B coil-sensing design. TRLYH1C is a contact-sensing design, so their diagnostic arrangements must not be treated as the same function when choosing replacement hardware.

IS200TRLYS1BGG carries the complete S1BGG identity. Other TRLY hardware forms implement different output or diagnostic arrangements; no separate revision is identified here as an approved interchangeable replacement.
