MTL MTL5514 Switch / Proximity Detector Interface

Specifications

• Number of channels: One
• Location of switch: Zone 0, IIC, T6 hazardous area
• Location of proximity detector: Zone 0, IIC, T4–6 hazardous area, if suitably certified
• Hazardous-area inputs: Inputs conforming to BS EN60947–5–6:2001 standards for proximity detectors (NAMUR). Voltage applied to the sensor is 7 to 9V DC from 1kΩ ±10%.
• Input/output characteristics:
  • Outputs closed if input > 2.1mA (< 2kΩ in input circuit).
  • Outputs open if input < 1.2mA (> 10kΩ in input circuit).
  • Hysteresis: 200µA (650Ω) nominal.
• Line fault detection (LFD): User-selectable via switches on the side of the unit. Line faults are indicated by an LED. The line fault relay is energized and the channel output relay de-energized if an input line fault is detected.
• Safe-area output: Single pole relay with changeover contacts.
• Relay characteristics:
  • Response time: 10ms maximum.
  • Contact rating (Safe Area): 250V AC, 2A, cosØ >0.7, 40V DC, 2A, resistive load.
• LED indicators:
  • Green for power indication.
  • Yellow for channel status (on when output energized).
  • Red for LFD indication (on when line fault detected).
• Maximum current consumption: 25mA at 24V DC.
• Power dissipation within unit: 0.6W at 24V.
• Operating temperature range: -20°C to +65°C (-6 to +149°F)
