Product Description:

The EL4032 analog output terminal is produced by Beckhoff within the EL EtherCAT Terminals series. As a two-channel voltage output module, it attaches directly to an EtherCAT I/O node and delivers analog setpoints from the controller to field devices such as actuators or proportional valves. By converting digital process values from the bus into precise voltage levels, the terminal supports decentralized motion or process control without additional gateway hardware.

This terminal draws power for its internal electronics through the EtherCAT E-bus, eliminating separate logic wiring. The field supply for the output stage is 24 VDC, so the control cabinet source that feeds sensors can also energize the channel drivers. Each terminal provides 2 single-ended outputs with a nominal conversion depth of 12 bits. This resolution provides 4,096 discrete voltage steps for fine control of downstream devices. The terminal switches the channels in a multiplexed sequence, allowing both outputs to share the precision converter while keeping the bus data width compact. Distributed Clocks support aligns sample timing with sub-microsecond accuracy, and the process image occupies two 16-bit words that map directly to the PLC.

The housing spans 35 mm on the mounting rail and supports variable installation orientations to fit tight panels. Its IP20 enclosure rating requires installation inside a cabinet while permitting tool-free insertion into adjacent terminals through the integrated contacts. Output current returning through the shield conductor is limited to 100 mA, while the common zero-volt conductor can carry up to 500 mA. These current limits help maintain predictable voltage levels under load and prevent ground loops. A single-ended ground reference simplifies wiring for actuators that share a common negative conductor. Fixed screwless terminals also simplify field wiring and reduce the need for installation tools.
