Product Precautions
Honeywell 900B16-0202 is a ControlEdge HC900 analog output module with sixteen user-scalable 0–21.0 mA channels. Its outputs are isolated in four groups of four and include output-current feedback and stored calibration data.
- Sixteen independently scalable current outputs
- Four isolated groups of four output channels
- Output-current feedback with calibration diagnostics
- Selectable internal or external 24 VDC field power
Before replacing 900B16-0202, record all sixteen channel ranges, terminal numbers, load assignments and the internal/external 24 V power selection. Restore the approved configuration and verify commanded versus measured current for every used output.
Important Notice: Verify 900B16-0202 from the physical marking and current manufacturer documentation before installation or configuration.

Apter Power 900B16-0202 Product Technical ReferenceHoneywell ControlEdge HC900 I/O Modules Specifications 51-52-03-41Important Notice: Use these model-specific records together with the current manufacturer publication and the installed-system documentation.
Control-valve positioning
Drives sixteen 4–20 mA final-control elements from HC900 control strategies.
Process setpoint transmission
Sends isolated current references to drives, analyzers or remote instruments.
Multi-loop analog control
Groups four channels per isolation domain for compact process-control cabinets.
Redundant calibration recovery
Uses nonvolatile factory and field calibration records for controlled maintenance.
Read the applicable Honeywell instructions before work. Verify 900B16-0202 and the installed system configuration.
1
Verify the complete 900B16-0202 marking and installed HC900 rack position.
2
Record all sixteen channel ranges, terminal assignments and connected loads.
3
Place every affected control loop in the approved maintenance state.
4
Confirm the internal/external power DIP selection before wiring field power.
5
Do not exceed 750 ohm load or the published current and voltage limits.
6
Observe the four groups of four isolation boundary; channels within a group are not isolated from each other.
7
Use the documented 900TCK-0001 terminal block and verify terminal torque and polarity.
8
Command and measure every used output, then confirm diagnostics before control-loop release.
Technical notes
Before replacing 900B16-0202, record all sixteen channel ranges, terminal numbers, load assignments and the internal/external 24 V power selection. Restore the approved configuration and verify commanded versus measured current for every used output.
