Detailed Product Description

MTL5511 (1-channel, with line fault detection)

Enables a safe area load 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 the channel is selected by a switch on the side of the module and output is provided by changeover relay contacts.

SPECIFICATION

See also common specification

Number of channels

One

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.

A line fault is indicated by an LED.

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

Single pole relay with changeover contacts

Note: reactive loads must be adequately suppressed
