MTL4544A 2 channel Transmitter repeater, passive input made in England isolated barrier
MTL4544A product specification as below
MTL4544A isolated barrier 2 channel Transmitter repeater, passive input
MTL4544A/AS –
MTL5544A/AS CURRENT REPEATER 4/20mA passive i/p for HART® transmitters The
MTLx544A provides an input for separately powered 4/20mA transmitters and also
allows bi–directional transmission of HART communication signals superimposed
on the 4/20mA loop current, so that the transmitter can be interrogated either
from the operator station or by a hand-held communicator (HHC). Alternatively,
the MTLx544AS acts as a current sink for a safe-area connection rather than
driving a current into the load.
