2-channel pulse width output 24 V DC EJ2502

EJ2502 | 2-channel pulse width output 24 V DC

The EJ2502 output modulates the pulse width of a binary signal and outputs it electrically isolated from the E-bus. The mark/space ratio is prescribed by a 16 bit value from the automation unit. The output stage is protected against overload and short-circuit. The EJ2502 has two channels that indicate their signal state via LEDs.
