2.6 EL1124, EL1144, EL1134 - Introduction
Four-channel digital input terminals + 5 / 12 / 48V
DC
The EL1124 (5V
DC
), EL1144 (12V
DC
) and EL1134 (48V
DC
) digital input terminals acquire the binary control
signals and transmit them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT
Terminals contain four channels that indicate their signal state by means of light emitting diodes. These
versions have different input voltages.
