The MTLx516/C enables two safe-area loads to be controlled by a switch or proximity detector located in a hazardous area.
The line-fault-detect (LFD) facility detects open or short circuit conditions in the field wiring and indicates them on the top of the module.
Phase reversal for each channel is selected by a switch on the side of the module, and the output is provided by changeover relay contacts.

Specification

Number of Channels: Two
Location of Switches:
- Zone 0, IIC, T6 hazardous area
- Div. 1, Group A hazardous location
Location of Proximity Detector:
- Zone 0, IIC, T4–6 hazardous area if suitably certified
- Div. 1, Group A hazardous location
Hazardous-Area Inputs:
- Inputs conforming to BS EN60947–5–6:2001 standards for proximity detectors (NAMUR)
- Voltage applied to sensor: 7 to 9V dc from 1kΩ ±10%
Input/Output Characteristics:
- Normal Phase:
  - 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) (When Selected):
  - User-selectable via switches on the side of the unit.
  - Line faults are indicated by an LED for each channel.
  - The channel output relay is de-energised if an input line fault is detected.
  - Open-Circuit Alarm:
    - On if Iin < 50µA
    - Off if Iin > 250µA
  - Short-Circuit Alarm:
    - On if Rin < 100Ω
    - Off if Rin > 360Ω
  - Note: Resistors must be fitted when using the LFD facility with a contact input:
    - 500Ω to 1kΩ in series with switch
    - 20kΩ to 25kΩ in parallel with switch
