HiC2025ES, SMART Transmitter Power Supply

SMART Transmitter Power Supply, HiC2025ES 1-channel isolated barrier 24 V DC supply (bus powered) 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) Up to SIL 3 acc. to IEC 61508 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 separate fault output on the bus is signaled, if the input signal is outside the range of 3 mA ... 22 mA. This device mounts on a HiC termination board. The device supports the following SMART protocols: HART
