HIMA F3322

Technical Specifications

16 digital‑output‑channels; rated per‑channel load 0.5 A (12 W) resistive or inductive load; power consumption 5 VDC 110 mA, 24 VDC 150 mA plus field‑load‑current; short‑circuit‑current‑limiting threshold 550 mA; module width 4TE; maximum 10 pieces of F3322 per I/O‑subrack; maximum total simultaneous‑switching‑load 8 A; recommended slow‑blow fuse 4 A; operating temperature ‑20 °C ~ +60 °C; IP20 protection grade.

Functional Features

Built‑in per‑channel short‑circuit‑current‑limiter; automatic all‑output‑shut‑off upon loss of L‑ power‑supply; supports parallel‑output‑switching without external free‑wheeling‑diodes; continuous channel‑diagnosis; module‑status‑LED indicators; compatible with H41q‑H51q safety‑controller subrack‑system.

Application Scenarios

Emergency‑shutdown‑valve driving, burner‑valve safety‑actuation, safety‑relay‑control, turbine trip‑circuit‑output, petrochemical and power‑plant safety‑instrument‑systems.

Performance Parameters

Output‑response‑time less than 10 ms; inductive‑load internal‑energy‑absorption; galvanic isolation between field‑output‑circuits and internal‑system‑bus.

Material Composition

Euro‑card printed‑circuit‑board with conformal‑protective‑coating; metal front‑panel; plug‑in field‑wiring‑terminal‑blocks; industrial‑power‑semiconductor output‑driver‑components.

Structural Features

Euro‑card plug‑in form‑factor for installation into H41q‑H51q‑I/O‑subrack; front‑panel status‑LED indicators; rear‑edge connector mating to subrack‑back‑plane; removable plug‑in terminal‑blocks for field‑actuator‑wiring connection.

Working Principle

Safety‑controller sends logic‑commands through subrack‑back‑plane‑bus to F3322 module; module output‑driver‑circuits switch 24 VDC power to connected field‑actuators; internal current‑monitor‑circuits detect short‑circuit‑events and activate current‑limiting; fault‑conditions are reported back to safety‑controller for safety‑logic‑handling.

Installation Requirements

Insert module into H41q‑H51q I/O‑subrack designated‑slot and lock front‑panel‑screws; connect field‑actuator‑wires to plug‑in terminal‑blocks; apply recommended 4 A slow‑blow fuse on module‑field‑power‑loop; total simultaneous‑output‑load shall not exceed 8 A per subrack; install inside ventilated control‑cabinet, separate power‑wiring from signal‑wiring.

Usage Precautions

Strictly observe maximum‑per‑channel‑load and subrack‑total‑simultaneous‑load‑limits; inductive‑actuator‑loads are permitted without external diodes; short‑circuit‑fault‑will auto‑recover after fault‑removal; power‑loss on L‑supply will force all outputs to safe‑off‑state; do not hot‑swap during safety‑system‑online‑operation; replace whole‑module for hardware‑failure, no component‑level‑repair allowed.
