Features
• 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

Function
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.
It transfers the analog input signal to the safe 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 acc. to NAMUR NE44 and a
separate collective error message output.
Test sockets for the connection of HART communicators are
integrated into the terminals of the device.
Application
The device supports the following SMART protocol:
• HART
