MTL1142隔离器，MTL1142隔离器，MTL1142隔离器模拟量输入隔离器，适用于变送器，输入信号4-20mA，输出信号4-20mA，满足有源、无源输出，并且带HART协议采集。

The MTL1142 is a Single Channel Analogue Input isolator with current source or current sink output (switch selectable). HART communication is provided for Smart two wire transmitters. 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 separay. 10 x 2 way power clips are provided to power 20 modules. The MTL1991 is used to feed power onto the bus.
