EL3318
Product Description
EL3318 is a Beckhoff EL EtherCAT Terminal with eight inputs for temperature and millivolt measurement. It supports B, C, E, J, K, L, N, R, S, T, and U sensors, as well as direct mV signals, with type K selected as the default sensor type. The inputs use 2-wire connection technology, and open-circuit recognition detects broken or disconnected sensor wiring. The maximum cable length is 30 m.
The terminal has an electrical measuring range of ±75 mV and 16-bit internal resolution for converting input signals into process data. Its preset temperature resolution is 0.1ºC, allowing temperature values to be reported in tenths of a degree. The process image occupies 16 bytes of input data and 8 bytes of output data for communication with the EtherCAT controller.
Bus-side isolation is rated at 500 V, providing electrical separation between the field connections and bus electronics. The differential destruction limit is ±15 V, while the ground destruction limit is ±50 V. Its ground potential limit is ±30 V. The IP20 protection class provides protection against contact with fingers and similarly sized solid objects but does not protect against water. The housing measures 12 mm in width, 100 mm in height, and 68 mm in depth.
