ICS Triplex T9802

Description

• Input Type: Dry contact / 24V DC wet contact
• Input Load Resistance: 5.125kΩ
• Channel Fuse: 50mA 125V Type T fuse
• Maximum Wire Cross-section: 1.31mm²
• Operating Temperature: -20°C ~ +70°C
• Weight: 140g

  Function Features:

• Support dual and triple modular redundant system architecture
• Independent isolation for each signal channel
• Fault self-diagnosis of input line circuit
• Compatible with contact position feedback signals of field equipment

  Working Principle: Collect switch state signals from field limit switches, emergency stop buttons, transmit signals to redundant digital input modules, detect circuit short-circuit and open-circuit conditions.

  Material Composition: Conformal coated circuit board, impact-resistant ABS housing, tin-plated wiring terminals.

  Structural Characteristics: Standard rack-mounted module, separated signal terminals and bus connectors; built-in replaceable fuse base.

  Application Scenarios: Safety interlock system emergency stop signal collection, equipment limit switch monitoring, fire and gas detection switch signal input.

  Installation Requirements: Digital input signal cables shielded and twisted pair; separate from analogue signal cables.

  Usage Notes: Dry contact signal lines should avoid long-distance parallel laying with AC power lines; prevent induced voltage causing false signal triggering.
