R0300 Compact Digital Temperature Controller, 96 x 96 mm, 2 / 4-Channel
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 position, 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
