2-wire temperature transmitter for DIN rails
2 galvanic isolated TC-inputs with cold-junction compensation
Signal pass-through time:
     without Butterworth filter ≤ 3 ms      with Butterworth filter ≤ 38 ms
Installation in zone 1 or 2 permissible
Intrinsic safety according to IEC/EN 60079-11
Error indication according to NAMUR NE 43
Green LED for Signal indication

Easy operation:
Power supply via rail or terminal
Simple assembling

Certified:
SIL2 according to IEC/EN 61508:2010
IECEx - Ex ib [ia Ga] IIC T4 Gb
ATEX II 2 (1) G Ex ib[ia] IIC T4

The 2-wire temperature transmitter MTP300i- SIL-K has been designed for the operation of intrinsically safe thermocouple circuits installed in the Ex area. Each TC-input terminal is equipped with a Pt100 sensor for the cold- junction compensation. The TC transmitter must be intrinsically safe supplied by a repeater power supply or ZENER barrier. Both thermocouple signals are galvanic isolated. The devices can be installed in zone 1 or 2 with the “n” (IEC/EN 60079-15) protection type.
