JUMO Quantrol - Compact Controller
The Quantrol series is available in the DIN format 48 mm x 48 mm. It is used for two-state and three-state control applications as well as for the control of regulating valves or SCR power controllers via a continuous controller output.
The universal analog input for RTD temperature probes, thermocouples, or current/voltage signals is user programmable. The setpoint value, the actual value, and all parameters are displayed on LED displays (red/green). The values can be displayed in °C or °F as preferred. The switch position of the relays or logic outputs is displayed using yellow LEDs. Different functions can be assigned to these outputs. An analog output 0 to 10 V or 0(4) to 20 mA can be configured as a continuous controller output, actual value output, or setpoint value output. Using the binary input, the device settings and operation can be locked, a ramp or the timer can be activated, or autotuning can be initiated. The voltage supply is optionally AC 110 to 240 V or AC/DC 20 to 30 V.
The controller has a ramp function with adjustable gradient for constant setpoint change. In addition, a special firing curve for small pottery kilns can be used which allows controlled starting and time dependent firing. The user can enter setpoint values, gradient, and firing time directly at the device.
The device can be connected to host systems or devices using the RS485 serial interface. Instead of operating the device from the front, the user can also program the controller using the setup program and USB interface; this requires no additional voltage supply for the controller. The Quantrol series, like all JUMO controllers, is also equipped with reliable JUMO autotuning.
