Product Description:

The EL1862-0010 is a digital input terminal produced by Beckhoff as part of the EL EtherCAT Terminals series. In an EtherCAT I/O rack, the unit captures discrete sensor states and forwards them to the controller through the internal bus, allowing compact signal aggregation inside industrial automation panels. It occupies a single 12 mm wide slice and converts field-level 24 V signals into the serial process image used by the EtherCAT protocol, supporting high-speed machine control. Its narrow form factor helps preserve rail space when many I/O points must fit beside couplers, power terminals, and motion components.

The module provides 16 inputs, each referenced to common ground and mapped as one bit in a 16-bit process image. Sensors operate at a nominal field level of 24 VDC, and internal circuits isolate these channels from the logic side by up to 500 V. Mechanical installation is straightforward because the housing snaps onto a 35 mm DIN rail, and the enclosure meets the IP20 protection class for sheltered switch cabinets. Signals arrive through a flat-ribbon cable terminated on two 10-pin male headers set at a 0.1-inch pitch, so preassembled harnesses can simplify wiring. Typical per-channel input current is 3 mA, which keeps the load on connected sensing devices low.

The terminal’s internal electronics draw an E-bus current of 100 mA, while the separate 24 V field supply requires only 45 mA. A built-in RC network establishes a 3 ms input filter that removes contact bounce before state changes are passed to the controller. The channels use ground switching, so sensors share the same reference conductor, and the device can be mounted in any orientation because of its variable installation position. This layout works well with typical 24 V industrial sensors and switches that need stable signal transfer on a dense EtherCAT terminal stack.
