The EP1816-0703 EtherCAT Box with digital inputs acquires binary control signals from the process level and transfers them electrically isolated to the controller. The signal state is indicated by means of LEDs. The signal connection is established via spring-loaded connectors, optionally available in 1- and 3-pin versions. Thanks to the compact plug level, the EP1816-0703 can transfer 16 signals from the field via EtherCAT in a very small space.
The sensors are supplied from the control voltage US. The load voltage UP is not used in the input module, but it can be optionally connected for forwarding.
The EP1816-0703 has three additional hexadecimal ID switches. In this way, an individual address from 0...4095 can be set, allowing unique identification regardless of installation position, as required by some device profiles for certain industries, such as the semiconductor industry.
The module is supplied without connectors.
