Description

Designed for decentralized automation tasks in rugged environments, the EPP1816-0008 EtherCAT P Box acquires binary control signals from the physical process level and transmits them with high speed and synchronization to the control system. The unit is equipped with 16 digital inputs configured in a highly dense arrangement, accessible via a standard 25-pin D-sub interface.

Operating as an EtherCAT P device, this module integrates both ultra-fast EtherCAT communication and power distribution (for both system/sensor supply Us and peripheral voltage Up) into a single, specialized cable. The inputs conform to the EN 61131-2 Type 1 and Type 3 electronic standards, ensuring broad compatibility with 2-wire and 3-wire proximity sensors, limit switches, and photoelectric sensors. Built-in Distributed Clocks functionality guarantees precise latching of input states relative to the master system time.

Features

  • 16 digital input channels packaged in a compact, field-mountable form factor.
  • Unified EtherCAT P interface integrating power and signal on P-coded M8 connectors.
  • Concentrated sensor connection via a 25-pin D-sub socket with UNC4-40 locking threads.
  • Short-circuit proof, integrated sensor supply derived directly from the Us control voltage.
  • Hardware-supported Distributed Clocks for microsecond-precise input sampling.
  • IP67-rated enclosure allowing mounting outside electrical control cabinets.

Applications

  • High-density sensor data acquisition in assembly and packaging machinery.
  • Decentralized input mapping in conveyor and material handling systems.
  • Automated production lines requiring field-level modular expansions.
  • Machine tool control and robotics end-of-arm tool feedback integration.

Installation Guidelines

  • Ensure the installation surface is flat and clean to guarantee a proper seal when mounting. Secure the housing using M3 screws through the integrated mounting holes.
  • Use only pre-assembled, shielded EtherCAT P cabling with P-coded M8 connectors to protect the physical layer and preserve the IP67 protection class.
  • When connecting sensors via the 25-pin D-sub interface, verify that the total load current drawn does not exceed the maximum sensor supply rating of 0.5 A.
  • Establish a reliable, low-impedance ground connection via the mounting profile or the designated grounding point on the module's body.
