Working Principle: Transmit digital switching control signals from backplane I/O modules to field solenoid valves, contactors; provide circuit overcurrent protection via built-in fuses, upload circuit fault signals to safety controller.
Material Composition: FR4 circuit board, flame retardant ABS shell, tin-plated copper terminals, quick-replace fuse holders.
Structural Characteristics: Horizontal rack-mounted card structure; front wiring terminal block, rear 96-way bus connector; detachable terminal baffle.
Application Scenarios: Chemical plant safety interlock, power auxiliary machine on-off control, pipeline emergency shutdown valve control, offshore platform safety control system.
Installation Requirements: Install inside dust-proof control cabinet; avoid installation near heat sources; wiring terminals torque controlled within 0.6–0.8 N·m.
Usage Notes: Replace fuses with specified model only; do not increase fuse rating; avoid capacitive and inductive load without freewheeling diode; prohibit live plugging.
