Data Sheet

Programmable controller, 6 relays
Type CSTFR1

Electronic controller suitable for all HVAC/R software application needs.

CSTFR1 is an electronic programmable
controller especially dedicated to refrigeration
market and that allows full multiplexed cabinet
management. Thanks to the software
customisation possibility, it can be used in
several types of application. It’s also available
with optoinsulated Modbus RS485 serial
communication interface.

Features:

• 5 analog and 4 digital inputs

• 1 analog and 5 digital outputs

• Insulated power supply 110 / 230 V AC, 50/60
Hz

• Remote access to data through CANbus
connection for additional display (LCD
available) and keyboard

• Modbus RS485 opto-insulated serial interface

• Available only without display

• Dimensions 8 DIN modules
