Controllers

Gefran offers a series of solutions for all applications requiring accurate and safe PID control. Actions needed to address today’s challenges in various sectors of industry.
Gefran offers a wide range of products that are scalable in both performance and features. PID controllers are designed with a special focus on ease of use and configuration. 

BASIC SERIES

THE ESSENTIAL CONTROLLER

Four different models for multiple temperature
control applications in industrial processes.
Simplicity and practicality are combined with the experience of PID control.
  • Operator interface with double LED display
  • Universal input • Hot, cold and hot/cold PID settings with automatic tuning
  • Interrupted, total and partial load alarm
  • Loop Break Alarm
  •  Up to four relay outputs, logic for SSR
  • Analogue control and retransmission outputs
  • RS485 serial communication in Modbus RTU 
  • Dimensions 1/16, 1/8, 1/4 DIN

PERFORMANCE SERIES
