■ Overview
The following digital electronics modules can be used for con-
necting actuators/sensors in the context of SIMATIC PCS 7:
Digital input modules
• EM 8 DI DC 24 V High Feature
- Digital electronics module with eight inputs
- Suitable for standard switches and proximity switches
(BEROs)
- Rated input voltage 24 V DC
- Diagnostics "Short-circuit of sensor supply to ground" per
channel
- Diagnostics "Open-circuit" per channel
- Process alarm
- Parameterizable input delay
Digital output modules
• EM 4 DO DC 24 V; 2 High Feature
- Digital electronics module with four outputs
- Suitable for solenoid valves, DC contactors and indicator
lights
- Output current 2 A per output
- Rated load voltage 24 V DC
- Diagnostics "Short-circuit of outputs to ground" per channel
- Diagnostics "Short-circuit of outputs to P" per channel
- Diagnostics "Open-circuit in outputs" per channel
- Diagnostics "Load voltage missing" per module
- Parameterizable substitute value
■ Technical specifications
For detailed technical specifications of the digital electronics
modules, see:
• Catalog IK PI
• Mall/CA 01 under "Distributed I/Os / ET 200pro"
B) Subject to export regulations: AL: N, ECCN: EAR99H
■ 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)
