Temperature control unit
GMC Instruments
The R0300 multi-channel controller with DDC algorithm is suitable for temperature regulating processes at injection molding, extrusion, textrusion, packaging, and film blowing machines, as well as in ovens.
The standard version includes the following functions:
* Digital display for actual value and setpoint
* Display of system deviation as 2-color bar graph
* Differential and follow-up control for 2 control channels only
* Externally activated alternative setpoint
* Regulated temperature is maintained in the event of sensor failure
Depending upon order configuration, the controller is equipped with the following characteristics:
* 2 or 4 control channels
* Two position, three poisiton, step, continuous-action or hot runner temperature control
* Hot runner start-up switch
* Relay or transistor output
* Self-optimization
* Two limit contacts: MIN and MAX, absolute / relative, make / break contact
* Sensor input for thermocouple types J / L, K, S / R or PT100 (2/3-wire) or standard signals: 0/2..10V and 0/4..20mA
* RS 485 / TTY communications interface (20 mA)
* Auxiliary voltage: 24V AC, 110V AC, 120V AC, 220V AC, 230V AC, 240V AC
