Beckhoff EL2502 original PWM output

The Beckhoff EL2502 is a 2-channel PWM output terminal for the EtherCAT I/O system. Based on the Beckhoff naming convention, the "EL" prefix indicates an EtherCAT terminal, and "2502" identifies the PWM (pulse-width modulation) output function and channel configuration. It provides PWM output signals for controlling proportional valves, heaters, lamps, and other devices requiring duty-cycle control, connected to the EtherCAT network via the terminal bus.
