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.

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

Digital output module SM 1222 
Modules with 24 V DC outputs, relay outputs or relay outputs changeover.

Digital hybrid module SM 1223 
Digital hybrid modules offer digital inputs and outputs in one device with a small footprint.
