The MTL4573 temperature converter changes low-level DC signals from THC or RTD sensors into a 4/20mA current. You can use it for sensors located in hazardous areas (Zone 0, IIC). Software configuration covers linearisation, ranging, and sensor failure settings. This model also supports thermocouple types J, K, T, E, R, S, B, N and Pt100, Pt500, Pt1000 RTDs.
The MTL4644D repeater power supply powers 2-wire or 3-wire 4/20mA transmitters. It repeats the current to drive two loads. This unit also supports HART communication on output channel 1. You get a fully floating DC supply with high accuracy and fast response.
