Analog Input/Output Modules | The appropriate accuracy for each task

The GIO212 is a module that can measure and output various types of signals. Each channel can be used as analog or digital output or input. With the standard signals current (0/4 to 20 mA) and voltage (±10 V), various sensors and actuators can be connected. A resolution of 16 bits allows measurement results from signals that do not completely use the measuring range (e.g. 0 to 5 V). Temperatures are playing a significant role in ever more processes, which is why this module supports Pt100/Pt1000 in 2-, 3-, and 4-wire measurement, as well as all standard type thermoelements. Similarly, the channels can be used as digital inputs, which can also be configured as interrupt input and digital 32-bit counters. The values of the pulse length or period measurement can be puffered in a FIFO (1022 values).

The quick digital 24 V output can be selected as Push-Pull, High-Side or Low-Side. The output can be controlled as simple output or as PWM / frequency output. The frequency mode allows the control of the stepper motor output stage via the output of the number of pulses or freely selectable profiles (FIFO).

Up to two signal types can be used simultaneously per channel. This allows up to 24 channels per GIO212. Analog sensors can be supplied via the digital output (short circuit-proof and monitored), actuator signals read back and digital signals monitored analog. Thus, this is a single universal module for countless applications instead of different modules for each signal type. A cost-effective solution that simplifies logistics and service.

Various modes can be combined and set easily via a configuration wizard in the SolutionCenter engineering tool.

The AIO208 and AIO216 modules enable the measuring or output of all standard analog signals. The AIO208 offers 8 channels and the AIO216 16 channels compactly in a single module. The standard signal types for current (0 to 20 mA and 4 to 20 mA) and voltage ranges (±10 V to ±10 mV) allow the connection of a wide range of sensors and actuators. A minimum 14-bit resolution makes it possible to also measure signals that do not fully utilize the measuring range (e.g. 0 to 5 V) with a sufficiently high resolution.

Temperatures are playing an important role in an increasing number of processes. These modules therefore also support Pt100/Pt1000 in 2, 3 and 4-wire measuring circuits, as well as all standard thermocouples. For each channel, a second channel with unused signal types can be used in addition to the primary configured signal type. For example, a current output can be assigned to a voltage input so that up to twice the number of channels per module are provided. This enables one module to cover virtually all analog signal measuring tasks instead of having to use many different modules for each signal type.

A cost-effective solution that simplifies logistics and servicing. Different modes can be combined and set simply using a configuration wizard in the SolutionCenter engineering tool.

All conventional analog signals are measured or emitted by modules AIO208/SI, AIO204/SI and AIO202/SI. AIO208/SI has 8 channels, AIO204/SI has 4 channels and AIO202/SI 2 channels isolated compactly and individually in one module. A wide variety of sensors and actuators can be connected using standard current (0 to 20 mA and 4 to 20 mA) and voltage range (±10 V to 100 mV) signal types. A 16-bit resolution also enables measurements from signals that do not make full use of the measuring range (e.g. 0 to 5 V) at sufficiently higher resolution. Temperatures are playing a major role in more and more processes, which is why these modules support Pt100 in 2-, 3-, and 4-wire measurement, as well as all standard type thermoelements.

Input and output are available on every channel. If, for example, the voltage input is used in most instances, the free output as a secondary channel can be used for the current output, for instance, so that double the number of channels are available per module.

This enables virtually all analog signal measuring tasks to be covered easily in a single module instead of using many different modules for each signal type. An economical solution that simplifies logistics and service as well as enabling the flexible use of reserve resources.

The temperature recording modules TI214/x provide 14 temperature measuring channels in a single module width. With the TI214 either Pt100/Pt1000 sensors in 2 and 3 wire technology or type J or K thermocouples can be connected to each measuring channel. The TI214/2 module allows for the connection of type N or S thermocouples. The sensor type can be individually selected for each channel. In this way, the most effective and cost-efficient solution can be implemented for the application. The average determination of the measured value can be set between 16 fold and 64 fold for easy an reliable interference suppression.

With the module version TI214 the temperature of the switching cabinet can be measured on the same module with an inexpensive Pt100 sensor, while for example the temperature control systems are fitted with thermocouples.

The new 3-wire measuring evaluation of the Pt100/Pt1000 sensor compensates the voltage error of both symmetrical cable runs and enables the precision of complex 4-wire measuring technology to be implemented in inexpensive 3-wire technology. The Pt sensors can also be connected in simple 2-wire technology and this is sufficient for many applications with short measuring lines.
