PRODUCT INFORMATION
Product Overview
The Honeywell 900B01-0001 is a four-channel Analog Output Module designed for ControlEdge controller systems. This module delivers individual current outputs ranging from 0 to 21.8 mA across each channel. It provides high galvanic isolation rated at 500 VDC between individual channels. Isolation from controller logic is rated at 600 VDC to prevent electrical interference.
The unit executes digital-to-analog conversions with a 12-bit operational resolution. Output updates occur synchronously with the execution cycle of the primary controller. Integrated diagnostics monitor internal calibration data, configuration states, and incoming 24 VDC power. Field wiring loops support resistive loads up to 750 ohms maximum per channel.
