PID Temperature Controller - Economy Range - 48Wx48Hx61D

The NEX316 (48x48) PID Temperature Controller from Radix  is a cost effective & economical model in the Economy Range. It has an easy-to-read, large display and compact size. This PID temperature controller is used in applications such as food processing machines, plastic extruders and moulding machines, packaging machines, ovens and small furnaces. Its precise temperature control provides a reliable solution at an affordable price.

NEX316 accepts five types of thermocouples -  J, K, R, S, T - and Pt100 RTD inputs. All these inputs are user settable through keys (not factory selected). No DIP switch is used. Thus, if a user needs to change the input type from thermocouple J to Pt100 RTD, he can easily do so through the keys. This feature allows dealers as well as end-users to use one product instead of multiple instruments for different inputs. NEX313 has a high input accuracy : thermocouple : ± 0.25% of span ±1 °C, RTD Pt100 : ± 0.05% of span ±1 °C, and maintains high accuracy throughout the operating temperature of -10 to 50 °C. Sampling time is 200 ms. The ‘Digital Filter’ parameter removes the fluctuation when the inputs have electrical noise. Many parameters such as Input Bias and Input Limits allow the instrument to adapt to any application. Sensor break detection is automatic and the relay can be selected to be on or off during sensor break.

NEX316 has a dual-row, three-digit display. The upper row is a large,13.2mm (0.52”), bright red display, and the lower row is a 9.9mm (0.39”), bright green LED display. This makes it easily viewable from far. The dual display shows both the process value and control setpoint value in the run mode. The dual display makes it easy to configure parameters. 

NEX316 is an easy to use product with four user friendly keys. The programming and setting of parameters can be easily done by any layman or technician. The programming levels and parameters are designed such that any parameter can be found easily. The setpoint can be quickly and easily set without going into program mode.

NEX316 is a single-setpoint PID temperature controller with an advanced PID and fuzzy logic algorithm. All the PID parameters can be set by the user or can be autotuned Autotuning is preferred for precise control. The procedure for autotuning is simple, fast and gives good accuracy. The controller can be easily converted from PID action to On-Off action by setting a single parameter. When On-Off action is selected, all parameters related to PID action such as band, integral time, etc. are hidden to make it easy for the user . Similarly, NEX316 can be easily set for only time proportional mode.

NEX316 has both relay and SSR outputs available. This minimises the varieties of order codes for dealers as well as end-users. The end-user can select either output by just setting a parameter and wiring at the proper terminals.

NEX316 is compact with a depth of only 60 mm behind the panel. This makes it useful in tight spaces with limited depth.

Also available in the Economy series of PID Temperature Controllers are NEX313 (similar to NEX316 but with a single display) and NEX353 (similar to NEX313, but of size 96Wx96Hx35D mm).
