Product Name: BECKHOFF EL3208 8-Channel Input Terminal
Product Brand: BECKHOFF
Product Code: EL3208
Product Artikel: BECKHOFF EL3208 8-Channel Input Terminal
The EL3208 analog input terminal allows eight resistance sensors to be connected directly. The EtherCAT Terminal circuit can operate sensors using the 2-wire technique in a compact 12 mm housing. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.1 °C. Sensor malfunctions such as broken wires are indicated by error LEDs.
