The Honeywell 900B08-0202 is an 8-channel analog output module for the ControlEdge HC900 system. It converts digital control signals from the HC900 CPU into precise analog current outputs, driving actuators such as valves, variable frequency drives (VFDs), and dampers. This module ensures stable process control and reliable performance in industrial automation environments.

Precision Control Modulation
The 900B08-0202 offers stable 4-20 mA signals for driving control elements with high repeatability, ensuring accurate response to PID algorithms and reducing process variability.
Failsafe Configuration
Each of the 8 channels can be programmed to hold the last value or transition to a safe output level during controller failure or communication loss, protecting critical equipment.
Integrated Diagnostic Monitoring
The module continuously monitors output integrity, detecting faults like open circuits (e.g., broken field wires) and reporting them directly to the HC900 CPU for immediate action.
Slimline Design
With a compact 2.2 cm width, the module offers high I/O density in the HC900 chassis, allowing engineers to deploy multiple analog output modules in a single rack for complex multi-loop control.
Does this module require an external power supply for the loops?
The 900B08-0202 typically draws power from the HC900 backplane. Ensure your power supply (e.g., 900P01) has sufficient capacity for all 8 channels at 20 mA.
Can I output voltage signals (0-10V) from this module?
No, the 900B08-0202 outputs only current signals (0-20 mA / 4-20 mA). For voltage outputs, use a different module designed for that purpose.
Is the 900B08-0202 compatible with older HC900 racks?
Yes, this module is compatible across the standard HC900 hardware range. Ensure the correct model number and revision are configured in Hybrid Control Designer.
What is the condition of the hardware?
We guarantee that the module is 100% Brand New, unused, and ships in its original Honeywell packaging to meet all manufacturer standards.
