MTL3011 AND 3012 SWITCH /PROXIMITY DETECTOR RELAYS MTL3011 – volt-free contacts 

MTL3012 – solid state

These basically similar units both enable a safe-area load to be controlled by a proximity detector or switch located in a hazardous area, the MTL3011 having a relay output for general use, and the MTL3012 a floating solid-state on/off switch compatible with logic circuits. In both units a built-in phase-reverse control allows an alarm condition (output open) to be signalled for either state of the sensor. A line-fault detection feature opens the output in the event of short or open-circuit lines: intended for use primarily with proximity detectors, it can also be used with switches made to resemble them electrically by adding two resistors, or disabled by a link if not required.

Div 1, Group A, hazardous location

Location of proximity detector

Zone 0, IIC, T4–6 if suitably certified

Div 1, Group A, hazardous location

Voltage applied to sensor

7.7 to 9.0V dc from 1kΩ

Input/output characteristics

Output closed if >2.1mA* (<2kΩ) in sensor circuit

Output open if <1.2mA* (>10kΩ) in sensor circuit

Hysteresis: 200µA (650Ω) nominal

*NAMUR and DIN 19234 standards for proximity detectors

Phase reverse facility

Operation reversed by switch on top of unit

Power supply failure protection

Output circuit opens if supply fails

Broken/shorted lines protection

By built-in line-fault detection feature (LFD)

Output open if input current <100µA (broken line)

Output open if input current >6.5mA (shorted lines)

Note: to prevent false triggering of LFD, switch-type

sensors must be fitted with resistors as shown or LFD be

disabled by linking terminals 7 and 8
