■Accessories

Connection modules

Actuators and sensors are connected using commercially-avail- able 5-contact M12 plugs on the connection module. The con- nection module is plugged onto the electronics module, and screwed to the latter. The following connection modules (to be ordered separately) are available for the above-mentioned elec- tronics modules:

• CM IO 4x M12 (for EM DI and EM DO)

• CM IO 8x M12 (for EM DI)

Depending on the selected connection module, each plug for the 8-channel digital input module has one or two channels:

• 4 x M12 round plug connections with 2 channels per plug (double assignment)

• 8 x M12 round plug connections with 1 channel per plug (single assignment)
