NEX235 is a series of AHU controller, PID Controller, Temperature Indicator, On/off Controller, Indicator with alarms and Process controller with RPM indication manufactured by Radix.

Three universal analog inputs are included in NEX235; the input types are: 14 thermocouple inputs; RTDs inputs(Pt100/Cu53/JPT100); 0-50 mV, 0-10 V and 4-20 mA. As well as three analog outputs which are 4-20/0-20/20-4/20-0 mA. In NEX235 the sensor break protection and cold junction compensation is customized by the user (or is user programmable)..

The Process Controller NEX235 features two relays with NO-C-NC, NO-C contact types and includes a 12 VDC drive signal for an external SSR. The sampling interval is set to either 50 ms or 200 ms, depending on the program configuration and transmitter supply will be 22 V (nominal), 30 mA (maximum). The maximum load for current output is upto 500 ohms and voltage output is greater than 10k ohms in NEX235 Process controller. It includes a 3 x 4 digit, 7-segment 0.56" (14.2 mm), with red LED display.

The communication in the process controller NEX235 available is Modbus® RTU connectivity with Isolated RS485 and the user programmable baud rate comprises from 2400 to 57600. Bumpless Auto/Manual control is provided. NEX235 has a supply voltage of 85-265 VAC with frequency 50/60 Hz or 18~30 VDC. The Enclosure is certified flameproof for gas groups IIA & IIB with material aluminium alloy.

NEX235 process controller comes with size 355x85x165 mm with ingress protection IP66 (IEC) / NEMA 4X rating. 4 pushbuttons are provided to control the 2 setpoints, programming and alarm acknowledgement.
