MTL5516C MTL Instruments Switch/Proximity Detector Interface

The MTL5516/C enable two safe-area loads to be controlled by a switch
or proximity detector located in a hazardous-area. When selected, open
or short circuit conditions in the field wiring are detected by the linefault-detect (LFD) facility and also indicated on the top of the module.
Phase reversal for each channel is selected by a switch on the side of
the module and output is provided by changeover relay contacts.

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
Open-circuit alarm off if Iin > 250µA
Short-circuit alarm on if Rin < 100Ω
Short-circuit alarm 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
