Pepperl-fuchs HID2031 Current Driver, Part no:121478. 1-channel isolated barrier, 24 V DC supply (bus powered), Current output up to 750 Ω load, Low power dissipation, Housing width: 18 mm, Number of channels: 1-channel, Transfer direction: to the field, Rated voltage: 20.4 ... 30 V DC bus powered via Termination Board, Signal: 1 x 4 ... 20 mA, Field device: 1 x positioner, Field device [2]: 1 x I/P converters, Field device [3]: 1 x visual alarm, Signal: 1 x 4 ... 20 mA.
Function
This isolated barrier is used for intrinsic safety applications. It repeats a 4 mA ... 20 mA input signal from a control system to drive I/P converters, valve actuators, and displays located in a hazardous area.
An open field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by control systems.
This module mounts on a HiD Termination Board.
