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
