Description
Product Overview
The IS400TRLYS1B Relay Output Terminal Board by GE features 12 plug-in magnetic relays for flexible control applications. Outputs 1–6 support jumper-configurable Form-C contacts or solenoid drivers. Outputs 7–11 offer isolated dry contacts, while Output 12 handles special loads like ignition transformers.
This board supports both simplex and TMR configurations. Use connector JA1 for simplex setups and JR1, JS1, JT1 for TMR systems. The board includes jumper-selectable fuses and suppression circuits for solenoid power management.
