R7101 3HE 16TE 8-channel 19" Temperature Controller Module
The R7101 control module 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:

• Two position, three position, step or hot
  runner temperature control for each channel

• Start-up switch for hot runner
  (with external activation)

• Externally activated alternative setpoint

• Regulated temperature is maintained in
  the event of sensor failure

• Switching outputs: 24 V_DC for SSR

• Heat current monitoring with R7701 data concentrator and GTZ4121 current transformers

• Auxiliary voltage: 24 V_DC

Depending upon order configurations, the controller is equipped with the following characteristics:

• Self-optimization

• 4-channel differential control

• 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

• Switchable reference junction for thermocouples

• External setpoint

Special accessories:

• R7701 Data Concentrator for heat current monitoring with two R7101 controller modules

• GTR7401 Rack for mounting 5 controller modules, or 4 controller modules and 2 data concentrators

• GTR7601 connector cable from data concentrator to controller module
