Detailed Product Description

MTL5517 (2-channel, line fault detection, phase reversal)

MTL5517 Enables two safe-area loads to be controlled, through a relay, by proximity detectors or switches located in a hazardous area.

Line faults are signalled through a separate relay and indicated on the top of the module. Switches are provided to select

phase reversal and to enable the line fault detection.

Number of channels

Two

Location of switch

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 by switches on the side of the module. 

Line faults are indicated by the LED for each channel.

Line fault relay is energised and channel output relay deenergised if input line-fault 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

Channel: Two single-pole relays with normally open contacts

LFD: Single pole relay with changeover contacts

Note: reactive loads must be adequately suppressed
