Honeywell 900B01-0101 Analog Output Module

Configured for analog signal output generation in ControlEdge HC900 control systems, the Honeywell 900B01-0101 (900B01 Analog Output Module) provides direct electrical execution. The module delivers four isolated analog output channels and converts controller output values into field current signals for process control devices and final control elements.

Hardware Specifications

4-20 mA Output and Channel Isolation

The module generates isolated analog current outputs for communication with field instruments and control devices. The output range extends to 21.8 mA, allowing over-range operation beyond the standard 4-20 mA control span. Channel-to-channel isolation reduces the transfer of electrical noise between output circuits and supports independent signal transmission to connected loads.

Frequently Asked Questions

Q: How many analog outputs are available on the module?
A: The module provides 4 isolated analog output channels.

Q: What output signal range is supported?
A: Each channel supports a current output range from 0 mA to 21.8 mA.

Q: Is channel isolation provided between outputs?
A: Yes. The module is specified with 4 isolated output channels.

Field Installation Guidelines

• Install the module only in a compatible HC900 controller rack or base assembly.

• Verify output wiring polarity before energizing field loops.

• Route analog output cables separately from AC power wiring.

• Connect shielded signal cables according to the site grounding design.

• Confirm load resistance remains within the control system requirements.

• Check field device calibration after loop commissioning.

• Inspect terminal connections periodically for loosening caused by vibration.
