NEX2xx is a series of full-featured PID controllers manufactured by Radix. With autotuning PID and fuzzy logic controls. These PID controllers are used in a host of industrial control applications for temperature, pressure, level, flow, humidity and other parameters. The NEX2xx series comprises DIN sizes 116, ⅛ , ¼ (48x48, 48x96, 96x48, 96x96). These PID controllers are also available in flame proof (explosion proof) versions for hazardous applications. Variants include 2-zone and 3-zone PID Controller, 2-zone and 3-zone Indicator with Alarms, PID Controller with Ethernet and Data logging, PID Controller with Wi-Fi and Data logging.

With two universal inputs NEX225 comprises input types: 14 thermocouple inputs; RTDs inputs(Pt100/Cu53/JPT100); RS485 MODBUS® RTU master input; 4-20 mA and 0-10 V. There are 6 digital inputs with potential free contact closure in NEX225 and 2 isolated analog outputs for control/retransmission. In the PID controller NEX225 the sensor break protection and cold junction compensation is customized by the user (or is user programmable). The control methods featured in this PID controller are Heat/Cool/Heat+Cool.

The NEX225 features 7 relays with Direct/Reverse action and 12 VDC drive signals for external SSR. Its sampling interval can be set to either 50 ms or 200 ms, depending on the program configuration. In this PID Controller NEX225 the maximum load for current output is 500 ohms and voltage output is greater than 10 Kohms. The PID controller features two large 7 segment displays, indicating Process Variables (20.32mm/0.8”) and the view mode shows maximum/minimum value of both the inputs. The communication in NEX225 includes MODBUS RTU connectivity with Isolated RS485 and the user programmable baud rate comprises from 2400 to 57600.

The NEX225 PID controller has a supply voltage of 85-265 VAC with frequency 50/60 Hz or 18-30 VDC. Bumpless Auto/Manual control is provided. This PID controller is compactly designed containing ingress protection Front IP66 (IEC)/NEMA 4X rating with housing material ABS plastic with grade UL94V-0 in size 96x96x60 mm. Some programmable parameters in NEX225 include soft start, remote setpoint input function, user selectable resolution, 4 PID groups, alarm acknowledgement, single ramp/soak time and autotuning function.

Other versions of NEX225 available : Process Controller with RPM Indication and Dual channel Indicator with Alarms. NEX225 is also available in a flameproof enclosure (I, IIA & IIB).
