2.2 Introduction
Fig.1: EM2042
The EM2042 Terminal Module combines 16 digital outputs in a Sub-D plug connector in a compact design.
The binary control signals are transferred (electrically isolated) to the actuators at the process level.
Like the standard Bus Terminals, the terminal modules are integrated in the I/O system.

3.1 Instructions for ESD protection
NOTE
Destruction of the devices by electrostatic discharge possible!
The devices contain components at risk from electrostatic discharge caused by improper handling.
• Please ensure you are electrostatically discharged and avoid touching the contacts of the device directly.
• Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling
with the devices.
• Each assembly must be terminated at the right hand end with an EL9011 or EL9012 bus end cap, to en-
sure the protection class and ESD protection.

3.2 Recommended mounting rails
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the terminals of the
EL66xx and EL67xx series can be snapped onto the following recommended mounting rails:
• DIN Rail TH35-7.5 with 1mm material thickness (according to EN60715)
• DIN Rail TH35-15 with 1,5mm material thickness
Pay attention to the material thickness of the DIN Rail
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the terminals of
the EL66xx and EL67xx seriesdoes not fit to the DIN Rail TH35-15 with 2,2 to 2,5mm material
thickness (according to EN60715)!
