MTL831C MTL Instruments  Analog Transmitter

The MTL831C Analog Transmitter can transfer a number of hazardous area input signals to the safe area down a data highway consisting of a single shielded, twistedpair cable. It is intrinsically safe and can therefore be mounted in Zone 0 hazardous areas or hazardous locations.
The MTL831C can monitor up to 16 inputs from THC or millivolt sources or 2, 3 or 4-wire RTDs or potentiometers. A data highway is provided that can carry both signal and power over distances up to 2km, depending on the application, the cable and the (noise) environment. Shielded twisted pair is highly recommended. At the other end of the data highway, an MTL838C Receiver translates the information transmitted from the MTL831C. One or two MTL831Cs may be connected to a single MTL838C.
The MTL838C provides a *Modbus® serial data output representation of the inputs together with status information. When the MTL831C transmitter is mounted in the hazardous area, the data highway must be protected by an MTL5553/MTL5053 Isolator/Power Supply mounted in the safe area.
