Product Description:
The EJ1809 EtherCAT plug-in module is essential for secure signal transfer and stable connection within networks. It is created by Beckhoff which has crafted an impressive standard in mechanical factories and several electrical industries.
The The << EJ1809 EtherCAT plug-in module’s electrical isolation of 500 volts between the E-bus and field potential is required for desirable signal separation in industrial automation. The housing unit consists of polycarbonate for supplying durable insulation composition. Its installation process takes place on signal distribution boards which enables stable connections through built-in mechanical coding features. The connection between the EJ module housing and signal distribution PCB relies on the combination of signal-specific pins and corresponding holes for mechanical coding. The coded system ensures that users avoid placing the wrong modules during installation. A security latching from it connects with the circuit board cut-out to enable vibration-proof use. An application-specific wiring level placed on the signal distribution board enables wire connection. The module attaches to the board through a 2 x 20-pin socket strip which assures continuous electrical linkage among both components.
The EJ1809 plug-in module design of 12 mm width has 66 mm height and 55 mm depth permitting it to fit into tight spaces. It also supports 16 digital inputs and follows EN 61131-2 with type 1 by 3 for defining “zero” signal voltage detection within negative 3 to positive 5 V. The “one” signal requires a voltage between 11 to 30 V according to specification category 3. The module operates under input currents of 3 mA according to EN 61131-2 type 3 specifications. The E-bus consumes almost 80 mA current while working which suits the system requirements effectively.
