Programmable Controller


TC49SU is a mid-range programmable temperature controller; feature-rich and cost-effective at the same time. It accepts input from 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt100 3-wire RTD sensors and optionally, 0 - 10 V DC and 4-20 mA or 0 - 20 mA linear inputs. A large LED display on the front of the temperature controller indicates the process value while 2 additional LEDs indicate the status of each of the two relays. Buttons on the front of TC49SU allow operators to easily program up to 2 setpoints for the process value. With an error of only 0.1% of full-scale value, this is a temperature controller of superior accuracy. TC49SU's two electromagnetic relays trigger heating, cooling or full-scale high and low alarms. It also retransmits an isolated current or voltage output signal to other devices such as a Programmable Logic Controller (PLC) or Solid-State Relay (SSR). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. TC49SU is conventionally an ON-OFF controller that outputs a discrete signal, but can also be used in Time-Proportioning Mode which turns the actuator on and off for periods proportional to the desired control effort, to emulate a continuous actuator that can generate a control effort between 0 and 100%. This product features Radix's proprietary sensor-break indication technology.
