SMART Transmitter Power Supply KCD2-STC-Ex1.ES
- 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
- Up to SIL 3 acc. to IEC/EN 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 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.
