New modules for the S7-1200

New modules expand the power of the S7-1200 CPU and provide the flexibility to meet your

automation needs:

● New CPU 1217C DC/DC/DC with high-speed differential points

● New and improved S7-1200 signal modules. The new signal modules (6ES7 2xx-xxx32-

0XB0) replace existing signal modules (6ES7 2xx-xxx30-0XB0). The new modules

provide:

– 4-20 mA range added to analog input and output modules

– Wirebreak detection when using 4-20 mA added to analog input modules

– Connector keying to prevent errors when plugging in field wiring connectors added to

modules with relay outputs

– Spare parts compatibility: you can employ the revised module in place of existing

modules without any changes.

● New spare parts available for use with S7-1200 CPUs

● New CPU 1217C Input Simulator (6ES7 274-1XK30-0XA0)

● New SM 1278 4xIO-Link Master (6ES7 278-4BD32-0XB0) functions as both a signal

module and a communication module, and allows connection of up to 4 IO-Link slaves (3-

wire connection) or 4 standard actuators or standard encoders

● New S7-1200 Potentiometer module (6ES7 274-1XA30-0XA0)

● New CM CANopen for S7-1200 is a plug-in module that allows you to connect CANopen

devices to the S7-1200 PLC. It can be configured to be both master or slave.
