Functional Features: 24‑channel safety‑digital‑output signal terminal distribution Group‑divided channel layout facilitates field‑loop grouping management Screw‑locking wiring terminals guarantee reliable field‑cable connection Interface matched with safety‑system main module via system interconnection cable Internal circuit supports safety‑signal output for solenoid valves and actuators Channel‑state feedback signal return path for system diagnosis Suitable for SIL‑level safety‑instrument‑system field‑wiring termination

Application Scenarios: Safety‑instrument‑system digital output field wiring termination Emergency‑shutdown system solenoid‑valve drive signal output terminal Petrochemical plant SIS system field actuator wiring interface Chemical‑industry safety interlock system field‑device termination cabinet Oil‑gas plant safety‑control cabinet field‑signal distribution

Material Composition: Housing: Flame‑retardant engineering plastic Terminal block: Reinforced nylon base with tin‑plated copper screw terminals Internal signal‑circuit board: FR‑4 flame‑retardant circuit board Cable‑interface connector: Gold‑plated multi‑pin industrial connector

Structural Characteristics: Rack‑mount modular structure, install inside control cabinet Multi‑group screw terminals arranged on front‑panel for field‑cable access Rear‑side multi‑pin connector for connecting to safety‑system main module by system interconnection cable Channel grouping partition structure for each four‑channel group No moving mechanical components

Working Principle: System safety‑digital‑output signal transmits from main safety‑module to FTA‑T‑02 through dedicated interconnection cable. Internal circuit distributes each safety‑output signal to independent screw‑terminal channel. Field‑site solenoid‑valve or actuator wiring connects to corresponding channel terminals. FTA internal circuit provides signal return path, enabling main safety‑module to execute field‑loop wire‑break and short‑circuit diagnosis. Each channel executes fail‑safe de‑energize‑to‑trip logic following safety‑system control instruction.

Installation Requirements: Mount inside industrial control cabinet, keep IP20 environment. Connect rear‑side multi‑pin connector with matched system interconnection cable to safety‑system main output module. Field‑site field‑device cable access front‑panel screw terminals, tighten terminal screws to specified torque. Separate safety‑system field‑wiring from non‑safety‑system power‑cable wiring. Complete cabinet protective ground connection. Keep ambient operating temperature within ‑20 °C ~ +65 °C.

Usage Notes: Do not exceed single‑channel maximum 2 A continuous current rating. Verify field‑device working voltage matches FTA‑T‑02 supported voltage range. Check cable‑connector locking condition after interconnection‑cable installation. Do not hot‑disconnect interconnection cable under safety‑system running status. Periodically inspect terminal screw tightening condition. Prevent conductive dust accumulation inside cabinet.
