Flameproof Controller

TEC302 (Flameproof)

TEC302 is a programmable temperature or process controller housed in a heavy-duty enclosure certified flameproof for gas groups I, IIA & IIB with IP65 rating - completely dust proof and a good level of protection against water. It can be wall-mounted or pipe-mounted. TEC302 is factory-programmed to receive input from one of 3 input groups: Group 1, which has Pt100 RTDs (standard), Group 2, consisting of 4-20 mA, 0-20 mA and 0-10 V DC linear inputs or Group 3 which contains Pt100 RTDs, 8 types of thermocouples (B, E, J, K, N, R, S, T) as well as 0-20 mA and 4-20 mA linear inputs. A large LED dual-display on the front of the controller shows the difference in values of the setpoint and process value while 1 additional LED indicate the status the single relay. Buttons on the front of TEC302, accessible through the flameproof enclosure, allow operators to easily program 1 setpoint for the process value. With an error of only 0.1% of full-scale value, this is a controller of superior accuracy. TEC302's electromagnetic relay triggers 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) or Solid-State Relay (SSR). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. TEC302 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.
