Programmable Controller


EC48S is a cost-effective programmable temperature controller. It accepts J-type (Iron/Constantan) and K-type (Chromel/Alumel) thermocouples as well as Pt100 RTD inputs. A large LED dual-display on the front of the process 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. Operators easily program 1 setpoint via membrane keys on the front of EC48S. With an error of only 0.1% of the full-scale, this is a process controller of superior accuracy. Typically, readings have a maximum error of ± 1 °C. The controller has 1 electromagnetic relay that triggers heating or cooling. EC48S 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.
