SMART Transmitter Power Supply
Description
This signal conditioner provides the galvanic isolation between field circuits and control circuits. 1-channel signal conditioner, 24 V DC supply (Power Rail), Input for 2-wire SMART transmitters and current sources, Signal splitter (1 input and 2 outputs), Dual output 0/4 mA .. 20 mA or 0/1 V .. 5 V, Terminal blocks with test sockets, Up to SIL 2 acc. to IEC 61508pa. The device supplies 2-wire transmitters, and can also be used with current sources. The device transfers the analog input signal to the control side as two isolated output signals. Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data. The output is selected as a current source, current sink, or voltage source via switches. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
