Introduction
The IQ201 panel mount universal process indicator is a precision digital indicator for interfacing to and measuring most
process variables. The IQ201 is capable of measuring and processing variables such as mA, Volts, Potentiometers,
Frequency, Counting, Ohms, mV, Thermocouples, RTDs and also has built in functions such as an Event Timer, Real
Time Clock (RTC option required) and a manual analog output station (Analog out option required). The IQ201 also
includes a multiple output excitation voltage selection for sensor excitation of 2 or 3 wire transmitters, encoders,
potentiometers and many more.
Calibration of the analog process variables is simply done by either entering in the display range selection or by direct
sensor injection calibration.
The high bright 6-digit 14 segment LED displays make for easy setup and readability. A simple menu system with built in
help hints allows for easy configuration of display and sensor settings.
A universal mains switch mode power supply (85-264VAC) is provided as standard but an optional low voltage (10-
30VDC) isolated power supply or a high voltage (25-70VDC) isolated power supply can be installed.
RS232 communications is supplied as standard with the MODBUS™ RTU and MODBUS™ ASCII protocol. A simple
ASCII out protocol is also provided for serial printing and communicating to large displays. A second communication
RS485 interface can be added in conjunction with the standard RS232 interface.
The IQ201 also has an analog out or an isolated analog out option to generate a precision 0/4-20mA and 0-10V analog
output signal.
The IQ201 also includes advanced features such as user input linearisation, max/min recording, programmable front
push buttons, programmable digital inputs, security menu lockout, advanced digital filtering, plus many more to provide a
truly universal process indicator.
