Operating on the \u003cstrong\u003eEtherCAT P\u003c\/strong\u003e protocol, this unit combines high-speed communication and 24 V DC power supplies (system\/sensor supply Us and peripheral voltage Up for loads) onto a single, standardized M8 connection cable. The highly flexible configuration allows each channel to operate as either a 3.0 ms filtered digital input (conforming to EN 61131-2, type 1\/3) or as a 0.5 A digital output, significantly reducing cable complexity and structural overhead in modern automation topologies.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Because the M8 P-coded connector carries system power (Us) and actuator load power (Up) simultaneously, total current through a single run must not exceed 3 A. If using inductive loads on multiple output channels, always calculate the cumulative peak current to avoid triggering an under-voltage error on the Up line, which will fault the box diagnostics.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo guarantee IP67 integrity, unused M8 ports must be sealed with IP67-rated protective caps. When terminating the M8 P-coded network connectors, use a calibrated torque wrench set to 0.4 Nm to prevent physical thread damage and ensure watertight gasket sealing. In high vibration settings (e.g., dynamic robotic arms), loop and secure the EtherCAT P network cable with a minimum bend radius of 10x the cable outer diameter to prevent continuous physical strain on the internal solder joints of the M8 socket.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Prior to physically installing, replacing, or configuring any device in an EtherCAT P topology, isolate the main power source and ensure that no voltage is present on either the Us (System) or Up (Load) lines.
