Product Description

The EL1904-0000 is a state-of-the-art Bus Terminal manufactured by Beckhoff Automation for the connection of several types of industrial sensors and actuators in a decentralized and efficient manner. This product is a TwinSAFE component designed for sensors with potential-free contacts for a 24 volts direct current. The terminal contains four inputs each of which is equipped with fail safe technology. The polycarbonate material used in the production of the housing of this product provide an unrivalled mechanical strength that is crucial in preserving the quality of the product for a long time.

Each digital input present on the EL1904-0000 is equipped with one Light Emitting Diode which provides information about the signal status at that particular input, also the typical time it takes to read and write information to the E-bus is about 4 milliseconds. The current consumption at the E-bus is approximately 200 milliamperes. Under ideal operating conditions, this product conforms to EN 61000-6-2/EN 61000-6-4 EMC immunity class, it also conforms to the EN 600068-2-6 vibration and shock resistance level.

Customers that purchase the EL1904-0000 can expect to use it at its best performance level for more than 20 years, also there is not need to carry out any elaborate proof test throughout this time period. Also, this product is a maintenance free device. It belongs to the IP20 protection class, and should be protected from the interference of dust, and any form of humidity. Also, it is recommended that the EL1904-0000 is installed horizontally on a 35 millimeters DIN rail before operation. Wake industrial provide customers that purchase this terminal from our store with a warranty that lasts for 12-month. For customers that require repairs, our engineers will complete any repair in 10 days or less.
