GE IS400TRLYS1FCB Relay Output Terminal Board

I. Basic Information
Brand: GE
System: Mark VIe / Mark VIeS gas turbine and steam turbine TMR triple-redundant control system
Product Type: 12-channel Form-C relay output terminal board (Terminal Board)
Matching I/O card module: IS410TRLYS1B (the main control I/O module, must be used in combination)
Suffix FCB: Hardware version, factory configuration batch code

 Core Functions
As the wiring interface board for the system and on-site equipment, it isolates the internal logic signals of the controller through 12-channel relays and drives equipment such as solenoid valves, on-site indicator lights, contactors, trip circuits, alarm relays, etc.
It realizes strong and weak current electrical isolation, suppresses on-site surges and electromagnetic interference, protects the main control I/O card, and is mostly used for unit protection trip, interlock control, sound and light alarm circuits.
Supports TMR triple-redundant safety architecture, meeting the SIL safety application requirements for key equipment in power plants.

Key Electrical Parameters
Channel Configuration: 12 independent single-pole double-throw (Form-C) relays, each channel includes common terminal COM, normally open NO, and normally closed NC
Contact Load Specifications
DC24V: Maximum 8A
DC48V: Maximum 1.2A
DC125V: Maximum 0.6A
AC120/240V: Maximum 3A
The first 6 contacts are wet contacts with fuse protection, and the last 6 are standard dry contacts
Wire Diameter: 12AWG~24AWG, fence-type wiring terminals
Operating Environment: 0~60℃ industrial cabinet temperature, wide temperature resistance to dust, oil, and strong electromagnetic interference

Hardware Compatibility Relationship
Main Control I/O Card: IS410TRLYS1B (installed on the back panel of the controller rack)
Matching Terminal Board: IS400TRLYS1FCB (on-site wiring board)
Connection Cables: Special I/O shielded flat cables to achieve signal interconnection between the card and the terminal board

Typical Application Scenarios
Mark VIe control system for thermal power / gas power plants steam turbine generators, combined cycle power plants, large-scale compressors in petrochemicals. It is used for:
Emergency trip interlock output of the unit
Control of solenoid valves for lubricating oil and cooling systems
Driving local / remote alarm indicators, sound and light alarm devices
Interlocking of high and low voltage switch cabinets, auxiliary machine start-stop control circuits
