Programmable Controller

TC48

TC48 is a mid-range programmable temperature controller; feature-rich and as well as cost-effective. 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 dual-display on the front of the temperature controller shows the difference in values of the setpoint and process value while 2 additional LEDs indicate the status of each of the two relays. Buttons on the front of TC48 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. TC48's electromagnetic relays trigger heating, cooling or full-scale high and low alarms. It also retransmits an isolated output signal to other devices such as a Programmable Logic Controller (PLC). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. TC48 is 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 output, to emulate a continuous actuator that can generate a control output between 0 and 100%. TC48 is failsafe for sensor break. The enclosure is a plug-in design, measuring 48x48x100 mm.
