The CAL 9900 series PID temperature controller is a microcontroller based unit for precise control with easy installation, suitable for support both heating and cooling applications. PID controllers offer proportional control over basic on/off controls allowing for a far more versatile and application friendly process control.

The 9900 series from CAL offer push to tune as well as auto tuning algorithms for fast accurate set up with the ability to tune all five control parameters automatically. The auto tune function within the controller allows the unit to tune during warm up. Alternatively, the Push-to-Tune function within the controller allows for tuning in more difficult applications. This allows tuning to be achieved even when the thermal conditions are substantially different.

Built in standard 1/16 DIN size, the 9900 series PID controllers are easy to mount in any DIN system and are suitable for use with DIN adapters to fit 1/8 and 1/4 DIN units. Along with its industry standard dimensions, the 9900 series are all IP54 rated suitable for use in areas with average levels of dust as well as being protected from water spray from any direction.

The four large control buttons teamed with the units large LED display make for an easy to use, easy to install and easy to commission unit offering reliability as well as easy in almost any application.

• 1/16 DIN (48 x 48mm) unit for easy installation
• Application versatility with heat-cool strategy
• Auto-tune or Push-to-tune at setpoint
• 5A output relay on main control output
• Dual output versions can plug into 11-pin base

The 991.12C features two relay outputs and uses a 230 V ac power supply.
