GE IS200TRLYH1BGF | TRLY Relay Output Terminal Board |

Core Functionality
A total of 12 pluggable Form-C (SPDT) relay channels; 1-6 channels support jumper switching: dry contact output/direct drive of on-site solenoid valve coils; The 7-12 channels are isolated dry contact outputs, and the 12th channel is specifically used for special load scenarios such as ignition transformers.
Hardware diagnosis of coil current, real-time detection of relay coil open circuit and short circuit faults; Upload fault information to ToolboxST software, with onboard status LED indicating channel status.
On board multiple circuit meltable power supply branches can provide 24VDC/125VDC/115-230VAC on-site power supply for electromagnetic valves, with independent fuse protection for each circuit and built-in MOV surge suppression circuit AX Control.
Support Simplex single, dual and TMR the third mock examination redundant architecture; The three-way processor signals JR1, JS1, and JT1 are connected to the board to complete signal aggregation and voting, and are adapted to the TMR unit system.
PCB triple anti coating, strong EMI filtering; Connect the on-site cables to the large terminal blocks on both sides; Four sets of IDC board connectors are connected to VCCC/VCRC processor cards.
Hot swapping is not supported, maintenance and replacement must be performed with power off; Static sensitive devices require anti-static grounding for disassembly and assembly.
