MTL3046B REPEATER POWER SUPPLY, 4/20mA for ‘smart’ transmitters.

The MTL3046B performs a similar function to the MTL3041, but is tailored for use with ‘smart’ transmitters whose digital communication signals are superimposed on a standard 4/20mA analogue signal.

The unit provides a minimum of 15V at 20mA to energise the transmitter while at the same time repeating the current accurately in

a separate circuit to drive a load in the safe area. The transmitter can be calibrated, interrogated or tested from the host computer, or by using a hand-held communicator connected in either the safe or hazardous area. The MTL3046B is a development of the MTL3046, which it replaces, and it is compatible with the majority of ‘smart’transmitters available.
