EJ3318
The EJ3318 is an EtherCAT plug in module by Beckhoff, part of the EJ EtherCAT Plugins series, designed for precise temperature measurement. It supports 8 thermocouple inputs using 2-wire technique and offers 500 Volts isolation between the E-bus and field. With a typical filter limit of 1 kHz, resolution of 0.1 °C per digit, and measurement error within 0.3%, it operates from –20 to 80 °C. The module draws 190 mA from the E-bus, measures 12 x 66 x 55 mm, weighs 30 g, and meets IP20 protection, UL approval, and CE certification.
