8-channel digital input 3.3 V DC/5 V DC EJ1128

EJ1128 | 8-channel digital input 3.3 V DC/5 V DC

The EJ1128 EtherCAT plug-in module acquires the binary 3.3 V DC/5 V DC control signals and transmits them, in an electrically isolated form, to the higher-level automation unit. The inputs feature HCT CMOS technology, i.e. the resulting switching thresholds allow the use of sensors with HC CMOS outputs as well as TTL outputs.

The power for the module (5 V DC) can be supplied via the EJ9505 power supply module.
