MTL5011B SWITCH/ PROXIMITY DETECTOR INTERFACE single-channel With Good Price In Ready Ship

MTL5011B SWITCH/ PROXIMITY DETECTOR INTERFACE single-channel, with line fault detection and phase reversal

The MTL5011B enables a safe-area load to be controlled by a switch or proximity detector located in a hazardous area. A relay output is provided. Phase reversal control allows an alarm condition to be signalled for either state of the sensor. A selectable line fault detect (LFD) facility detects an open or short circuit in the field circuit.

SPECIFICATION OF MTL5011B

Number of channels

One

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

Safe-area output

One relay with changeover contacts

Hazardous-area input

Input conforming to NAMUR/DIN 19234 standards for proximity

detectors

Voltage applied to sensor

7 to 9V from 1kΩ ±10%

Input/output characteristics

Normal (reverse) phase:

output energised (de-energised) if Iin >2.1mA or Rin <2kΩ

output de-energised (energised) if Iin <1.2mA or Rin >10kΩ

Hysteresis: 200µA, typical

Line fault detection (LFD)

User-selectable, via switches on the top of unit. Line faults are

indicated by an LED. A detected line fault de-energises the relay.

Open-circuit alarm on if Iin<100µA

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

500W to 1kW in series with switch

20kW to 25kW in parallel with switch

Phase reversal

User-selectable, via switches on the top of unit.

Relay type

Single-pole changeover relay

Note: reactive loads must be adequately suppressed

Relay characteristics

Response time: 10ms maximum

Contact rating: 250V ac, 2A, cosø >0.7

Red: LFD indication (on when line fault detected)

Maximum current consumption

40mA at 20V

35mA at 24V

25mA at 35V
