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
