EL3182 Beckhoff I/O Modules & Remote I/O

Part number EL3182 from Beckhoff, listed in I/O Modules & Remote I/O. KKM Solutions quotes this part with pricing and availability confirmed per order.

The Beckhoff EL3182 terminal is a high-performance module within the EL EtherCAT Terminals series, designed for reliable analog signal isolation and conversion. As an optocoupler with a phototransistor output , it provides galvanic isolation of up to 3750 Vrms between input and output circuits. Its primary application is to protect control systems from voltage transients and ground loops by transmitting analog signals via optical coupling. This optocoupler terminal leverages a robust 80 V collector-emitter voltage rating and a versatile current transfer ratio of 50%–600% , enabling precise signal reproduction across varying load conditions. The terminal demonstrates a typical switching time of 4 µs , facilitating rapid response in high-speed automation tasks. Maximum power dissipation is rated at 150 mW , and the device can withstand input reverse voltages up to 5 V . The soldering temperature tolerance of 260°C for 10 s allows secure PCB assembly without compromising internal components. These technical details, combined with the use of an LED input type and a phototransistor output, deliver accurate isolation and high signal integrity for analog input channels. Beyond its core isolation function, the EL3182 is certified to UL, cUL, and VDE standards, underscoring its compliance with stringent safety and reliability requirements. The module’s design accommodates numerous industrial environments, offering stable operation even at maximum forward current and elevated temperatures. With a maximum output current of 150 mA per connector, the terminal ensures durable channel protection against overcurrent conditions. Its compact form factor and high dielectric strength simplify integration into dense control cabinets. By combining high-voltage isolation, rapid switching, and broad industry approvals, the EL3182 enhances system safety and efficiency, making it an ideal choice for modern EtherCAT-based automation installations.
