Module Features & Control

Four fully isolated output channels prevent interference between connected field devices.
Wide output range (0-21.8mA) supports standard 0-20mA and 4-20mA signaling with overhead.
Configurable failsafe operation ensures predictable system behavior during communication loss.
Integrated output current verification provides closed-loop confirmation of commanded output.
Slew rate control allows limitation of output change speed to protect sensitive actuators.
Redundant factory calibration stored in non-volatile memory ensures long-term accuracy and reliability.
Diagnostics continuously monitor module health, flagging calibration or power supply issues.

Installation & Configuration

Install in a compatible Honeywell HC900 rack (e.g., 900R04-0300).
Do not exceed the maximum load resistance of 750 ohms per channel to ensure proper current output.
Use appropriate cable gauges for the required loop current and distance.
Configure each channel's output range (e.g., 4-20mA) and failsafe value via HC900 software.
Set the slew rate parameter to match the response time of the connected final control element.
Verify output current with a calibrated milliammeter during commissioning.
