The CN3420 Series Process Controller is a highly versatile, single loop controller in 1/4 DIN format that has been designed to be exceptionally easy to set up and operate.
Universal input and an integral transmitter power supply ensure that the CN3420 has the capability to measure a wide range of process signals such as temperature, pressure, flow and level.
The unit features enhanced performance with analog, logic and relay control outputs, all fitted as standard, and an option to add further I/O capabilities such as additional relays, remote setpoint, analog retransmission and digital input, as needed to suit your application.
The configuration of the CN3420 is achieved by moving the security switch and entering a simple code from the front panel keys or via our CN34-SW PC configuration package. There are no passwords, no input links, no complications.
With NEMA-4X/IP66 front panel and superior RF immunity standard, the CN3420 has been designed to control reliably in the harshest of today’s industrial environments.
