  • Product Name: 8-Channel Safety-Related Relay Output Module
  • Product Introduction: Part of HIMA HIQuad X / HIMatrix I/O suite, providing dry-contact relay outputs to drive actuators, valves, and alarm devices in SIL 3 safety loops.
Category:
Description
  • Technical Specifications:
    • Output Channels: 8​ independent safety relay outputs
    • Output Type: Dry contact (mechanical relay)
    • Contact Rating: Resistive 1 A 24 V AC/DC; Inductive 500 mA​ (12 W); Lamp load max 4 W
    • Switching Time: ≤ 10 ms
    • Supply Voltage: 24 V DC​ (18–30 V DC)
    • Current Consumption: 5 V DC: 130 mA; 24 V DC: 180 mA
    • Internal Voltage Drop: Max 2 V​ at 500 mA
    • Short-circuit Current: 0.75 … 1.5 A
    • Space Requirement: 4 TE
    • Operating Temperature: -40°C to +85°C
  • Functional Features: Integrated line monitoring (open/short detection); short-circuit protection per channel; safe disconnection on fault; read-back test of output signals.
  • Performance Parameters: SIL 3​ (IEC 61508), Cat. 4​ / PL e​ (EN ISO 13849-1); contact life ≥ 10^7​ operations.
  • Material Composition: Silver-alloy relay contacts; flame-retardant enclosure; industrial-grade PCB.
  • Structural Features: Plug-in rack module; front LEDs for output status and module fault; test pulse duration max 200 µs.
  • Working Principle: Redundant processor commands close/open relay via diverse output drivers; feedback contacts read actual position; discrepancy forces fail-safe open state; automatic walking-bit test verifies driver capability.
  • Advantage Highlights: Galvanic isolation between channels; hot-swap support; precise line surveillance reducing troubleshooting time.
  • Applicable Industries: Emergency Shutdown (ESD) Systems, Burner Management (BMS), Oil & Gas, Rail Signaling.
  • Model Series: HIMA F3 Series / HIQuad X.
  • Installation Requirements: Insert into compatible HIMA safety controller rack; ensure 24 V DC​ user supply fused appropriately; tighten screw terminals to specified torque.
  • Usage Precautions: Do not exceed 1 A​ resistive load per channel; avoid inductive spikes—use external suppression if load > 12 W; verify line resistance < 11 Ohm; cycle power after module replacement to clear fault latch.

HIMA XAL-TERM

Product Introduction:
The XAL-TERM is a field-termination or shunt/adaptor module used in conjunction with HIMA X-series analog or digital I/O modules (such as X-AI3201, X-DI…). It provides screw-terminal connections for field wiring (shielded cables) and often includes built-in terminating resistors (for analog loops) or jumper options, allowing field cabling to be disconnected without removing the electronic I/O module.
