In early 2018, Weintek released a high efficiency control solution: HMI+CODESYS+I/O Module, which has received positive feedback from customers. To make it a more viable solution for diverse industrial applications, Weintek has developed new iR Series module products: Analog I/O module and Temperature module. With these modules, users can capture analog signals (voltage, current, temperature), compute with HMI or controllers, and then output signals to control other units in the system. By providing a suite of useful features which works with minimal settings, iR Series can take care of the complex jobs that used to require PLC programming, and as a result can help save considerable amount of development time.
iR Series Analog Modules come in four models designed for different needs.
iR-AI04-VI Analog Input (4 channels)
iR-AQ04-VI Analog Output (4 channels)
iR-AM06-VI Analog Input (4 channels)+Analog Output (2 channels)
iR-AI04-TR Temperature Input (4 channels)

Features
- Analog Input Modules Configurable Channel Mode
- Each channel may be configured as input voltage or current mode (-10~+10V,
- 5V~+5V, 1~5V, -20~20mA, 4~20mA) for different applications.
User-Defined Conversion Rate
Built-in digital-to-analog conversion with user-defined range eliminates the need for writing complex conversion program in PLC.

Temperature Input
ModuleSupports most of the Thermocouple and RTD on the market Thermocouple J,K,R,S,T,E,N,B,C,L,U,TXK/XK(L),TBP/BP(A-1),TBP/BP(A-2),TBP/BP(A-3),M RTD PT100, PT1000, LG-N1000, Ni100, Ni1000, Cu50, Cu100 Voltage ±2V, ±1V, ±0.5V, ±0.25V, ±125mV Resistance 0-3000Ω、0-300Ω
- User-Defined Temperature Table
Apart from the temperature tables of common Thermocouple and RTD, users can defined their own temperature reference tables so that even when the sensor type is not in the built-in list, the user can still define corresponding temperature table and use the temperature module to collect temperature values from the sensors.
- Input Filter
The built-in filter enhances signal quality to achieve better control.
- Disconnection Detection
A channel alarm will be generated when input sensor disconnection is detected.

Case: Air Conditioning
In an air conditioning system, temperature modules can be used to detect the ambient temperature. The detected value is used by PID controller of PLC, which calculates and produces desired output via an Analog Output Module to the inverter and the compressor to maintain stable indoor temperature. The built-in digital filter can stabilize temperature readings, and the temperature module can generate disconnection alarm when a disconnection occurs for the onsite personnel to handle the situation.

Bonus: EasyRemoteIO
EasyRemoteIO is a PC software that allows users to configure and monitor all iR Series products. It is user-friendly and can help users to quickly learn the operation of iR Series products.
