MTL3012 SWITCH /PROXIMITY DETECTOR RELAYS Brand New with Good Discount 

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.

SPECIFICATION

Number of channels

One, fully floating

Location of switch

Zone 0, IIC, T6 hazardous area

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

OTHER APPLICATIONS

The MTL3012 can be used in some flowmeter applications. The

frequency response of dc to 2kHz and its ability to accept proximity

type inputs make it ideal for positive displacement (PD) meters and

some turbine meters.
