BECKHOFF EL1124 4-Channel Digital Input Terminal 5 VDC
Product Code:EL1124
Description
The EL1124 digital input terminal acquires the binary control signals and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal contains four channels that indicate their signal state by means of light emitting diodes.
