MTL1143信号分配器，MTL1143信号分配器，MTL1143信号分配器一进两出模拟量输入隔离器，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 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 separay. 10 x 2 way power clips are provided to power 20 modules. The MTL1991 is used to feed power onto the bus.
