Product Description:

The ES2022 belongs to the ES EtherCAT Terminals series manufactured by Beckhoff. It is a two-channel digital output module designed for 24 V DC control circuits in distributed I/O systems. When mounted on a DIN rail and linked through the EtherCAT backplane, it switches actuators quickly while sharing the E-bus and power contacts with adjacent terminals in an automation line.

The terminal is supplied with a nominal load supply of 24 V DC, and each channel can source up to 2 A/channel, allowing direct connection of solenoid valves or indicator lamps without external relays. Internal electronics draw only 100 mA from the E-bus, so the bus coupler can support many terminals before reaching its supply limit. Mechanical dimensions of 100 mm in height, 68 mm in depth, and a compact 12 mm width conserve cabinet space and help maintain convection airflow. Output stages energize in just 40 µs, minimizing delay between the controller command and field device activation. A 4-wire connection scheme separates the two load channels from the 24 V supply and ground conductors, which simplifies troubleshooting and keeps polarity assignment clear.

The power rail can carry up to 10 A through the integrated supply contacts, so several high-current loads may be daisy-chained without additional feed-in points. If a wiring fault occurs, the output stage limits the short-circuit current to <70 A and turns off within 200 µs; the stored energy released during shutdown remains below <1.7 J/channel, which helps protect connected devices. Two independent outputs, reverse-voltage protection on the supply pins, and a pluggable wiring level allow the terminal body to be removed without disturbing the field wiring, which helps preserve conductor placement in densely packed control cabinets.
