Page 9: Introduction
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. -
Page 10: Mounting And Wiring
• 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. Fig. 2: Spring contacts of the Beckhoff I/O components 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: •... -
Page 11: Mounting And Demounting - Terminals With Front Unlocking
• Attach the cables. Demounting • Remove all the cables. • Lever the unlatching hook back with thumb and forefinger (3). An internal mechanism pulls the two latching lugs (3a) from the top hat rail back into the terminal module. EM2042 Version: 2.1.0... -

Mounting and wiring • Pull (4) the terminal module away from the mounting surface. Avoid canting of the module; you should stabilize the module with the other hand, if required. Dimensions Fig. 3: EM2042 Dimensions Version: 2.1.0 EM2042... -
Page 13: Positioning Of Passive Terminals
The passive terminals have no current consump- tion out of the E-Bus. To ensure an optimal data transfer, you must not directly string together more than 2 passive termi- nals! Examples for positioning of passive terminals (highlighted) Fig. 4: Correct positioning Fig. 5: Incorrect positioning EM2042 Version: 2.1.0... -
Page 14: Connection
Fig. 6: EM2042 X1: Signal connection, digital outputs, D-Sub 25 The EM2042 digital output module transmits the binary control signals from the automation unit on to the actuators at the process level. The 16 outputs deliver load currents of up to 0.5 A, although the total current from all the outputs must not exceed 4 A. -
