Modular controller
HC900 Honeywell Process Solutions

The HC900 controller provides a cost-effective platform for combining loop and logic control. The HC900 is ideal for unit process applications that require a combination of analog process control functions and discrete control actions. When networked with the Experion system for supervisory control, the HC900 controller provides an ideal unit controller for standalone processes, skid-mounted systems and other periphery operations in a process facility.

The HC900 controller offers a blend of analog process, logic and sequencing control algorithms. There are no preset limits on the number of times a function block type may be instantiated in a controller (limit based on memory availability and required scan rate). Features include:

- 1,920 I/O points
- Compact 4, 8 or 12 I/O slot rack sizes
- Open Ethernet network connectivity
- Peer-to-peer data exchange
- Automated loop tuning
- Setpoint programmers
- Setpoint schedulers with multiple ramp/soak outputs andultiple 64-step sequencers
