PID controller that can be plugged into a static relay
For multi-zone systems controlled using RS485 Modbus
Description
PID DRR450 controller: multi-zone regulation directly on the static relay
The DRR450 from Pixsys is a PID thermoregulator without an LCD display, designed to be plugged directly into a single-phase static relay (SSR). Each heating zone thus has its own controller, which is controlled and monitored remotely via the serial connection.
Reduced wiring and assembly time
The direct connection to the power module eliminates the control wiring between the controller and the SSR. The 22.5 mm module mounts on a DIN rail, which allows for the alignment of numerous zones in a compact cabinet.
Integrated charge current measurement
The built-in current transformer monitors the current consumed by the resistance and triggers an alarm in case of a break or defect, valuable information for machines with multiple heating zones.
Control via RS485 Modbus RTU
Each DRR450 communicates in Modbus RTU slave mode, up to 128 nodes on the line. The commands, measurements and alarms are managed by the automation system, the operator’s panel or supervision.
A second programmable output
In addition to the SSR control, a second 24 VDC output is available for an alarm or for the hot/cold dual PID function.
Typical applications
Injection presses and multi-zone extruders
Hot ducts and heated molds
Packaging and thermal welding machines
Fours and tunnels with multiple zones controlled by an automatic system
