2 Product overview
2.1 Introduction
Fig.1: KM2042
The KM2042 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.

KM204210 Version: 2.0.0
3 Mounting and wiring
3.1 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
Note
Pay attention to the material thickness of the DIN Rail
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the ter-
minals 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)!
3.2 Mounting and demounting - terminals with front
unlocking
The terminal modules are fastened to the assembly surface with the aid of a 35 mm mounting rail (e.g.
mounting rail TH 35-15).
Note
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting
rail. At the installation, the locking mechanism of the components must not come into con-
flict with the fixing bolts of the mounting rail. To mount the recommended mounting rails un-
der the terminals and couplers, you should use flat mounting connections (e.g. countersunk
screws or blind rivets).
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation,
disassembly or wiring of the Bus Terminals!
Mounting
• Fit the mounting rail to the planned assembly location.
