The NEX211 PID Controller (48x48x61 mm) has one universal input. Input types include 8 thermocouples, RTDs (Pt100, 3-wire), 4-20 mA (DC current) and 0-50 mV; 0-10V (DC Voltage). The 4 to 20 mA input does not require any external resistor to be fixed at the terminals. This improves the accuracy greatly, apart from eliminating the inconvenience.
NEX211 has 1 isolated analog output (DC current - 4 to 20 mA, DC voltage - 0 to 10V) for control as well as retransmission. They can also be used as a setpoint output. The NEX211 PID controller has 2 relays with direct/reverse control action. Alarms in the NEX211 can be reset through user key or digital input.
Control modes in NEX211 include : PID, ON/OFF and Heat+Cool. The PID controller NEX211 has MODBUS RTU communication with isolated RS485. Baud rates can be programmed from 2400 to 57600 baud.
The NEX211 PID Controller features a large display for Process Variable (16.3mm/0.64”) and Setpoint (9mm/0.354”), and has backlit LEDs with labels for ease of use. Additional features of NEX211 include: soft start; bumpless auto/manual transfer; autotuning function; user friendly keyboard interface with password protection; and programmable sampling time of 200ms. The NEX211 PID temperature controller has a supply voltage of 85-265 VAC with frequency 50/60 Hz or 20-55 VDC. NEX211 PID Controller is housed in a 48x48x61 mm enclosure made of UL94V-0 ABS.
