Siemens S7-200 PLC expansion modules

Siemens S7-200 PLC expansion modules have a unified modular design - not great at the moment, Siemens S7-200 PLC module,Siemens S7-200 module,S7-200plc but an unlimited number of customized solutions for the future. All this makes the SIMATIC S7-200 Micro PLC a very and economical solution for automation control in a compact performance range.

Analog expansion provides analog input/output functions, the points are as follows:

1, adaptability can be applied to complex control occasions

2, directly connected to sensors and actuators, 12-bit resolution and a variety of input/output range can be directly connected to sensors and actuators without the need for external amplifiers, such as EM231 RTD module can be directly connected to the PT100 resistance thermometer.

3, when the actual application changes, the PLC can be expanded accordingly and the user program can be adjusted very easily.
