Location of proximity detector
Zone 0, IIC, T46 hazardous area if suitably certified
Div. 1, Group A hazardous location
Hazardous-area inputs
Inputs conforming to BS EN6094756:2001 standards for
proximity detectors (NAMUR)
Voltage applied to sensor
7 to 9V dc from 1k 10%
Input/output characteristics
Normal phase
Outputs closed if input > 2.1mA (< 2k in input circuit)
Outputs open if input < 1.2mA (> 10k in input circuit)
Hysteresis: 200A (650) 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 < 50A
Open-circuit alarm off if Iin > 250A
Short-circuit alarm on if Rin < 100
Short-circuit alarm off if Rin > 360
Note: Resistors must be fitted when using the LFD facility with a contact input
500 to 1k in series with switch
20k to 25k in parallel with switch
Safe-area output
Two single-pole relays with changeover contacts
Note: reactive loads must be adequately suppressed

The MTLx516/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 line-fault-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.
