MTL1143 Transmitter Power Supply with Repeat Output
1 Channel, Smart for 2/4-wire transmitters
The MTL1143 is a Single Channel Analogue Input isolator with dual outputs. HART communication is provided for Smart two wire transmitters via Output 1. The transmitter can be interrogated either from the operator station or by a hand-held communicator (HHC). Power for this module is supplied via the power bus embedded in the DIN rail. The PBUS6.2 kit must be ordered separately. 10 x 2 way power clips are provided to power 20 modules. The MTL1991 is used to feed power onto the bus.
