SMART Transmitter Power Supply
Description
This signal conditioner provides the galvanic isolation between field circuits and control circuits. 2-channel signal conditioner, 24 V DC supply (Power Rail), Input 2-wire and 3-wire SMART transmitters and 2-wire SMART current sources, Output 0/4 mA ... 20 mA current sink/current source, Terminals with test points, Up to SIL 2 acc. to IEC 61508pa. The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire SMART current sources. It transfers the analog input signal as an isolated current value. Digital signals may be superimposed on the input signal on the field side or on the control side and are transferred bi-directionally. The device provides a sink mode or a source mode output on the control side terminals. The device has an internal resistor. Use this resistor if the HART communication resistance in the control circuit is too low. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
