Core Functions
Isolation and Conversion of Strong and Weak Electrical Signals at the现场
Built-in multi-channel fuses and capacitive surge absorption circuits， transfer TMR tripleized signals from the control cabinet backplane to the on-site terminal block， achieving 24VDC switch quantity DI/DO signal wiring and electrical isolation， preventing short circuits and high voltage intrusion from damaging the main control I/O card.
32 DI Switch Quantity Acquisition + 24 DO Relay Drive Output
DI： Collect on-site pressure switches， temperature interlocks， valve positions， emergency stop buttons， etc.， passive or active switch signals；
DO： Output 24VDC through the onboard fuse circuit to drive solenoid valves， alarm indicator lights， trip relays， and unit interlock equipment.
TMR Tripleized Signal Distribution
Relying on the Trident triple redundancy architecture， the terminal board performs line distribution for three independent signals， with a three-out-of-two voting logic， preventing false actions due to single-point line faults and avoiding system shutdown.
Channel Hardware Fault Protection
Each DI/DO is equipped with an independent fast fuse， a single-channel short circuit only melts the fuse of this path， and will not cause the entire board to fail； supports channel-level fault diagnosis， the system can accurately locate short-circuit and open-circuit channels.

Hardware structure features
Dual-row green plug-and-unplug terminal blocks, cable crimping is firm, facilitating batch wiring, maintenance, and line removal;
Special high-density connectors in the middle, connecting to Trident system I/O main card to achieve three-way redundant signal transmission;
Full-channel EMC anti-interference design, with PCB three-proof coating, suitable for strong electromagnetic interference working conditions in power plants, chemical plants, oil and gas fields, etc.;
The base comes with a track clip, which can be directly installed on the standard DIN track, without the need for additional fixing brackets.

Typical application scenarios
ESD emergency stop system interlock signal acquisition and trip output in petrochemical, coal chemical, and oil and gas stations;
ETS for steam turbines and FSSS for boilers in thermal power plants, furnace safety protection, BMS combustion management system;
Anti-stall protection for compressors, safety interlock control for large turbine units;
F&G detection and alarm system for fire and gas, high-pressure safety protection system for HIPPS;
Replacement of old Trident system spare parts, technical renovation and maintenance of SIS safety system.

Compatibility and replacement instructions
The hardware pins and terminal definitions of the 9566-8XX series terminal base are fully compatible with the same series; only the firmware version differs, and they can be directly interchanged;
Replacement must be accompanied by the original Trident I/O main control card, and it is not compatible with the old Tricon TS3000 series cards;
Material number 7400150-370 is the hardware number of the board card, and 3000540-380 is the terminal base version number. They are one-to-one matched for use.
