SMART Transmitter Power Supply
Description
1-channel isolated barrier, 24 V DC supply (Power Rail), Input for 2-wire SMART transmitters and current sources, Output for 4 mA .. 20 mA or 1 V .. 5 V, Sink or source mode, Line fault detection (LFD), Housing width 12.5 mm, Connection via spring terminals with push-in connection technology, Up to SIL 3 acc. to IEC 61508pa. This isolated barrier is used for intrinsic safety applications. The device supplies 2-wire transmitters in the hazardous area, and can also be used with current sources. The device transfers the analog input signal to the non-hazardous area as an isolated current value. 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 DIP switches. A fault is signalized by LEDs and a separate collective error message output. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
