Right for your needs, high-performance, and space-saving
The input and output modules feature high channel density and maximum efficiency: The minimum variation between parts makes ordering, services, and spare parts inventories much easier.
The modules are also available in different versions to suit individual requirements. In addition to the standard modules, high-feature versions offer expanded functions and more powerful performance.
The narrow 25 mm modules with no parameterization or diagnostics are available at a particularly low price.
Digital Input Modules
The modules have high channel density and low parts variance. As a result, ordering, logistics and spare-parts inventory are considerably simplified.
High Feature modules with enhanced functionality are only available with the 35mm form factor. Modules with a width a width of 35 mm can be equipped with a front connector using screw terminal or push-in technology, the connector has to be ordered separately.
The narrow 25mm modules use a front connector with push-in technology which is included in the scope of delivery. The modules have the same mechanical structure as the 35 mm modules. They also offer the same operability and the same accessories. Moreover, the pin assignment in the wiring is unchanged. This means that circuit and wiring diagrams can be universally used.
The narrow, low-cost modules do not have any parameter assignment or diagnostics, so integration in the engineering is significantly easier.
The narrow 25 mm modules can be mixed with the 35 mm modules as required.

There is a new 35mm hybrid module offering 32 inputs (sinking/sourccing) as well as 32 output (sinking).
It can be used side by side with the 25 mm modules in one station as required.
The perfect combination of precision and convenience
Analog input modules are designed to record process signals, such as pressure or temperature, as 16-bit digital values. Depending on the measurement type of the module, they also enable measurement of current, voltage, and resistance, and the connection of resistance thermometers and thermocouples.
Analog output modules convert a 16-bit digital value into a current or a voltage and output this to the process. They are suitable for controlling proportional valves or small servo drives.
Analog input modules (AI)
Analog input modules record process signals such as pressure or temperature and forward them in digitalized format (16 bit format) to the control. They are suitable for measuring current (2-wire and 4-wire transducers), voltage, and resistance, as well as for the connection of resistance thermometers and thermocouples (measurement types depend on the module).

Expanded functions for analog outputs
- Oversampling (for SM 532 AQ 8XU/I HS)
The use of the oversampling function requires an isochronous configuration.
For analog output modules, the preset transmit clock is divided into up to 16 time-equidistant subcycles. A data packet is transferred by the controller to the module and written to the process divided into n equidistant subcycles. The read or output values are transferred in the user data of the analog module. This increases the address space of the module.
A major advantage of Oversampling is that no faster CPU-Cycle is required for recording the high temporal resolution measurements. - Isochronous mode (for SM 532 AQ 4XU/I HF)
With the "Isochronous mode" system property, measured values and process data can be acquired with a fixed system clock. The signal processing until switching on the output terminal occurs in the same system clock. Isochronous mode thus contributes to high quality of the controller and therefore to greater manufacturing precision. Possible fluctuations of the process response times are significantly reduced. Time-assured processing, i.e. the high deterministic response, can be used for a higher machine cycle.

SM 534 AI/AQ 4xU/I/RTD/TC / 2xU/I ST
The analog input/output module SM 534 offers 4 analog inputs and 2 analog outputs at a very small footprint and is therefore suited for use in the tightest spaces.
The four inputs support measurement of voltage, current, resistance, resistance thermometer and thermocouples. Resistance or resistance thermometer measuring is limited to two channels, output signals are current or voltage.
The narrow 25 mm module with Standard functionality uses push-in technology, the front connector as well as the components for shielding like power supply element, shield bracket, and shield terminal are included in the scope of delivery.
