Detailed Product Description

MTL5516/C Switch/ Proximity Detector Interface 2-Channel, With Line Fault Detection

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 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.

SPECIFICATION FOR MTL5516/C

See also common 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
