Which family should you consider?
| Requirement | Family | Note |
|---|---|---|
| Compact single PID loop | CM10 | 1/8 DIN, straightforward and comprehensive. |
| Universal controller / cascade / profiles | CM30 | 1/4 DIN, balancing I/O and functionality. |
| Dual loops and advanced strategies | CM50 | 1/2 DIN, large display and extended functions. |
| Controller installed directly in the field | CMF310 | IP66/NEMA 4X, wall or pipe mounting. |
| Indication / totalisation / alarms only | CM15 | Not a PID controller. |
| Up to 24 process signals, touchscreen | RVG200 | Paperless recorder with security and remote access. |
| Field-mounted recorder with up to 7 inputs | SM500F | IP66/NEMA 4X, wall, pipe or panel mounting. |
| Paper records / traditional applications | Commander C series | Still part of ABB's current range. |
FAQ
Frequently asked questions
What is the difference between a controller and a recorder?
A controller closes a loop and adjusts an output to maintain the process at its setpoint. A recorder acquires and stores data. Some Commander instruments combine both functions.
When should I use a standalone controller instead of a PLC or DCS?
For one or a few local loops, a simple operator interface, independence from the central system or retrofits without PLC/DCS changes.
Is CM15 a controller?
No. CM15 is a universal indicator with totalisation, alarms, maths, logic and communications, rather than part of the CM10/30/50 PID controller family.
Is C1900 obsolete?
No. ABB continues to list C1900, C1300, C1950 and C1960 in its circular-chart recorder portfolio.
