Product details
Product Description
BECKHOFF EL3602 is a high-precision 2-channel analog input terminal. It handles voltage signals in ranges ±10 V, ±5 V, ±2.5 V, and ±1.25 V. The 24-bit resolution ensures accurate digitization. It transmits data electrically isolated to the automation device. The EtherCAT Terminal uses differential inputs with common internal ground. LED indicators show the signal state for each channel.
