Features:
- Generates sixteen user-scalable 0–21 mA outputs for ControlEdge 900 control strategies.
- Separates field circuits into four groups while isolating all outputs from controller logic.
- Stores calibration data and reports current-flow feedback for individual output supervision.
Honeywell 900B16-0202 receives output values from the controller and converts them into field current loops.
Each four-channel group shares an isolation domain without isolating the four outputs from one another.
Selectable loop power and a 36-position terminal block define how the module is wired in the rack.
The Honeywell 900B16-0202 ControlEdge 900 Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Four-Channel Isolation Structure
- Group Assignment: Channels 1–4, 5–8, 9–12 and 13–16 form the four isolation groups.
- Channel Commands: Outputs inside a group share its isolation domain but retain separate current commands.
- Isolation Boundaries: Each group remains isolated from the other groups and from controller logic.
Rack or External Supply Paths
- Power Selection: The module switch chooses rack-supplied 24 V DC or an external field source.
- External Supply: External loop power enters through the dedicated terminal pair on the 36-position block.
- Rack Limit: Internal-power use is limited to two modules per rack because of backplane loading.
Output Monitoring and Failsafe Behavior
- Current Feedback: Current-flow feedback tells the controller whether current is present on an output.
- Diagnostic Records: Module and channel diagnostics supervise calibration and configuration records.
- Failsafe Values: Configured failsafe values are applied if controller communication is interrupted.
Field Wiring Arrangement
- Terminal Block: The Euro-style terminal block provides paired connections for all sixteen outputs.
- Supply Terminals: Terminals 35 and 36 carry the external 24 V DC supply when that mode is selected.
- Pair Numbering: Output-pair numbering follows the four-channel isolation-group structure.
