Product Description:

Introduced by Beckhoff, this EL2642 EtherCAT terminal has reed outputs for both its channels. The terminal deploys two-wire connection technology. This products design reveals potential-free contacts. The device features a 0.5 A current rating and a 48 VAC/VDC voltage rating. This unit has been designed to function like a 1 x 4 multiplexer. It portrays double input connections. The terminal uses reed relays to perform the function of switching elements.

This product is designed without distributed clocks. The device supports an ohmic-type load. This unit is CE Certified and is encased in a polycarbonate high-density housing. It has an inbuilt temperature measurement feature. The terminals reed switch depicts constant contact resistance. This product can measure even sensitive signals with its fast scanning operation. The device comprises two LEDs in its housing. This unit can withstand a 1 A peak current for 100 ms. Its reed relays have a fast switching cycle. The terminals inputs and outputs portray an analog nature. This product features multi-channel acquisition of analog signals. The device-associated switches depict electrical isolation. This unit delivers a simple and flexible switching of several test states in production-integrated test stations. Its switches can be integrated into a compatible EtherCAT system.

The terminal design supports a long service life for the reed relays. This product allows multiple sources or sensors to connect to an analog input channel. The device has no protection against a short circuit. This unit has no address or configuration setting. It deploys a cage clamp connection. The EtherCAT terminals power contacts and E-bus have a current consumption of 20 mA and 60 mA respectively.
