For wiring details and full specs, refer to Beckhoff EL3314 documentation.
New old stock; terminal has never been installed or powered.
Original Beckhoff red I/O Series box present; carton shows minor shelf wear and edge creasing from storage.
Module remains seated in factory window cut‑out, not removed for testing.
No printed manual included; technical documentation is available from Beckhoff online.
Suitable as a precision thermocouple input module for temperature monitoring and control in EtherCAT systems using EK1100 or Beckhoff embedded controllers.
Buyer should verify required thermocouple type and temperature range, and ensure EtherCAT configuration supports EL3314 terminals.
