Product Description:

The EL4012 EtherCAT terminal provided by Beckhoff operates like a terminal with analog outputs. This terminal is supplied with an electrically isolated power up to the process level with a 12-bit resolution. The product’s signal state is indicated by LEDs. This device relies on a 24 V supply to power its output stage. The unit comprises dual channels in a single housing. It shares its ground potential with a 0 VDC supply. This terminal features horizontal installation as the optimum installation position, although it can be installed vertically as well.

The product triggers analog output signals in the 0 mA to 20 mA range. This device incorporates distributed clocks with less than or equal to 1 µs precision. The unit has two green Run LEDs that highlight four different operating states. It also comprises two shield connections. This terminal portrays electrical isolation of the power supplied to it. The product’s input data is monitored with other data in a synchronous pattern. The device is associated with less than 100 ns accuracy across the system. The unit portrays an improvised mechanical load capacity. Its mounting error is less than +/-0.1% from 0 °C to 55 °C with respect to the fill scale value.

This EtherCAT terminal features protection against short circuit. The product has eight terminal points in the connector in its housing. This device features two positive power contacts and two negative power contacts. The unit’s ESD protection and protection class can be ensured only with an appropriate bus end cap termination at the right end. Its shield lines must be in the de-energized state at the connection time.
