Connection
EL1124, EL1144, EL1134 | 4-channel digital input terminals 5 V DC, 12 V DC, 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.
