Expanding the CPUs by using additional I/O s

simatic s7 1200 signalboard 172


The central processing units of the SIMATIC S7-1200 are designed as Compact CPUs with integrated I/Os. Their modular design can be used to increase the configuration limits or to adapt the controller to new tasks: through mounting a Signal Board on the CPU or adding separate signal modules.

Signal modules can be connected to the right of the CPU to further extend the digital or analog IO capacity. CPU 1212C accepts up to two, CPU 1214C, CPU 1215C and CPU 1217C both accept up to eight signal modules.

Signal boards can be added to the CPU to increase the number of digital or analog inputs and outputs, RS485 communication, and battery board to the controller for your application requirements without increasing the controller's footprint.

This provides users with the following advantages:

  • Optimal adjustment:
    With signal modules which can be mixed as desired, users can adapt their controllers exactly to the relevant task. Modules with 8, 16 and 32 input/output channels are available.

  • Flexibility:
    If the task is extended subsequently, the controller can be upgraded with one of these signal modules. Updating of the user program in TIA Portal is extremely simple.


Signal Boards

animation signalboards

Signal boards are connected directly to the front of the CPU. They can be used where space is limited or if only a few additional inputs/outputs are required.

Analog inputs for SIMATIC S7-1200

sm1234 ai aq 150

The SM 1231 analog input signal modules convert analog signals from the process into digital signals for internal processing by the SIMATIC S7-1200.

  • With extremely short conversion times

  • For connecting analog actuators and sensors up to 14 bit resolution and different input ranges without additional amplifiers.

  • For solving even more complex automation tasks. Updating of the user program is extremely simple.

RTD-Module SM 1231 
The SM 1231 RTD modules enable temperatures to be measured with high precision using resistance-based temperature sensors. 
The most popular resistance-based temperature sensors can be used. They are connected directly to the module without amplifiers and all RTDs must be of the same type. The sensors can be connected with 2, 3 or 4 cables.

Thermocouple modules SM 1231 
The SM 1231 thermocouple modules enable temperatures to be measured with high precision using established thermocouples. In addition, low level analog signals in the ±80 mV range can be recorded. Four thermocouples each of types J, K, T, E, R, S and N can be used. They are connected directly to the module without amplifiers. 
For maximum possible measurement and repeat accuracy, the thermocouple modules should be mounted in locations with low temperature variations.

Hybrid module SM 1234 
Analog hybrid modules offer digital inputs and outputs in one module with a small footprint.

Energy Meter Module SM 1238
The Energy Meter Module SM1238 is the ideal entry into machine-level energy management. 
The space-saving expansion module is just 45 millimeters wide, and can be used to record energy flows simply and precisely, directly on the machine. The measurements are processed directly in the CPU, and visualized with a Basic or Comfort Panel. The SM1238 Energy Meter module records measured electrical values, such as voltages up to 480 V AC, in a 1 or 3-phase network with a direct connection but without a transformer. The user can freely adjust the diagnostic parameters for over and undervoltage, overload, tolerance value and tolerance time. An external 1 or 5 ampere current transformer with a conversion factor of up to 10,000 is used to measure the current.

Digital inputs as supplement to the integral IO of the CPUs

sm1221 dc 150

The SM 1221 digital input signal modules convert the level of the external digital signals from the process to the internal signal level of the S7-1200.

  • For flexible adaptation of the controller to the task at hand. This avoids superfluous investment. Modules with 8, 16 and 32 input/output channels are available.

  • For subsequent extension of the system with additional input. If the task is extended subsequently, the controller can be upgraded with one of these digital modules. Updating of the user program in TIA Portal is extremely simple.

The portfolio comprises 12 different modules.
