HID2030 SMART TRANSMITTER POWER SUPPLY

Description

HID2030 SMART TRANSMITTER POWER SUPPLY

Features

• 2-channel isolated barrier
• 24 V DC supply (bus powered)
• 2-wire SMART transmitters or current sources
• Usable as signal splitter (1 input and 2 outputs)
• Dual output 4 mA … 20 mA or 1 V … 5 V
• Line fault detection (LFD)
• Up to SIL2 acc. to IEC 61508

Function

This isolated barrier is used for intrinsic safety applications. It provides a fully floating supply to power 2-wire SMART
transmitters in the hazardous area, and repeats the current to drive a safe area load. It is also used with 2-wire current
sources.
Digital signals may be superimposed on the analog values in the hazardous or safe area, which are transferred bidirectionally.
A separate fault output on the bus is signaled if the input signal is outside the range 0.2 mA … 24 mA. The fault conditions can
be monitored via a Fault Indication Board. This module mounts on a HiD Termination Board.

Application

The device supports the following SMART protocols:
• HART
• BRAIN
• Baily (only SST-02 communication, e. g. BCN series)
• Foxboro
