Radix has a large selection of mid-range and low-cost Programmable Temperature/Process Controllers. Our controllers accept a wide variety of inputs from RTD sensors, thermocouples as well as linear inputs such as such as 4 - 20 mA, 0 - 20 mA, 0 - 50 mV, etc. Large LED displays and LED lights on the controller indicate process variable, setpoint, and relay, communication status.These are easily visible to operators from a distance. Operators can easily program setpoints, alarms, control outputs on the controller via membrane keys on the front of the unit to trigger heating, cooling and high-low alarms. Our Programmable Temperature Controllers retransmit isolated current (4 to 20 mA, etc) or voltage (0 to 10 V, etc) outputs to protect downstream equipment and devices (such as PLCs)  from damage. These Controllers are also available in flameproof versions. Radix also offers full-featured PID controllers, differential controllers, blind temperature controllers, etc.
