Connection
Assembly
• 1-channel isolated barrier
• 24 V DC supply (bus powered)
• Analog input, digital input,
analog output, digital output
• No configuration required, device is self-adapting
•HART transparency
• Low power dissipation
• 3-way isolation
• Up to SIL 2 acc. to IEC 61508
Function
This isolated barrier is used for intrinsic safety applications.
The device can transfer the following signals:
- as an analog input: 0/4 mA ... 20 mA
- as an analog output: 0/4 mA ... 20 mA
- as a digital input: signals from NAMUR sensors or
dry contacts
- as a digital output: max. 45 mA
The device requires no configuration and adapts itself
automatically to the function of the active input/output of the
connected process control system.
The device permits the bi-directional pass-through of the
HART communication.
The device is designed primarily for use with universal I/O
cards (e. g. Honeywell Universal Process IO).
This device mounts on a HiC Termination Board.
