MTL4516/C – MTL5516C SWITCH/ PROXIMITY DETECTOR INTERFACE 2-channel, with line fault detection
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 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.

                           


MTL5516C product specification
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
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
Safe-area output
Two single-pole relays with changeover contacts Note: reactive loads must be adequately suppressed
Maximum current consumption :35mA at 24V
Power dissipation within unit 0.84W at 24V
LED indicators
Green: power indication Yellow: two: channel status, on when output energised Red: two: LFD indication, on when line fault detected
Safety description (each channel)
Uo=10.5V Io=14mA Po=37mW Um = 253V rms or dc
