Description
Order No.: 6ES7234-4HE32-0XB0 6ES7 234-4HE32-0XB0 6ES72344HE320XB0 SIMATIC S7-1200 analog I/O SM1234 Parameter: 4 AI/2 AO, +/-10 V, 14-bit resolution or 0 (4)-20mA, 13-bit resolution
Analog expansion modules provide the option for using further analog inputs/outputs in addition to the existing integral analog inputs/outputs.
This provides users with the following advantages:
Optimal adaptation
with analog signal modules, users can optimally adapt their controllers even to more complex tasks.
signal boards can be used where space is limited or if only a few additional inputs/outputs are required. Each S7-1200 CPU can be modularly expanded by a signal board. This does not increase the mounting space required for the controller.
Direct connection of sensors and actuators:
Up to 14 bit resolution and different input/output ranges permit the connection of sensors and actuators without an additional amplifier
Flexibility:
If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple
