MTL5014 SWITCH/ PROXIMITY DETECTOR INTERFACE With Good Price In Ready Ship

MTL5014 SWITCH/

PROXIMITY DETECTOR INTERFACE single-channel, dual-output, with phase reversal and line fault detection 

The MTL5014 enables two safe-area loads to be controlled by a single switch or proximity detector located in the hazardous area. The safearea interface has two changeover relays: output 1 and output 2. The output 1 relay reflects the status of the input and may be configured to operate in reverse phase. The output 2 relay may be configured either to repeat (slave) the output 1 relay, or to act as a line integrity monitor. A selectable line-fault-detect (LFD) facility enables an openor short- circuit fault to be detected in the field wiring.

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: 250µA typical

Phase reversal

User selectable

Relay type

Single pole, changeover contacts

Note: reactive loads must be adequately suppressed

Relay characteristics

Response time: 10ms maximum

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

 40V dc, 2A, resistive load

Contact life expectancy: 3 x 105 operations at maximum load

Line fault detection (LFD)

User selectable: Off or On

A detected line fault de-energises Output 1 relay

Open circuit alarm on if Iin< 100µA

Short circuit alarm on if Iin > 6.5mA

Note: For contact input, resistors must be fitted

500Ω to 1kΩ in series with switch

20kΩ to 25kΩ in parallel with switch

Output 2 mode

User selectable: Slave or LFD mode

In LFD mode, a line fault de-energises Output 2 relay

Open circuit alarm on if Iin < 100µA

Short circuit alarm on if Iin > 6.5mA

See note above on use of resistors

In Slave mode output 2 repeats output 1
