Opto 22 G4IDC5 G4 DC Input, 10-32 VDC, 5 VDC Logic, 4000 Volts I/O Isolation, 5ms Turn-on/off Time, 25 mA Input Current

Opto 22's G4 DC input modules are used to detect on/off DC voltage levels. Each module provides up to 4000 volts (transient) of optical isolation between field inputs and the logic output of the circuit. Typical applications for DC input modules include sensing the presence or absence of voltage and sensing contact closure from sources such as proximity switches, limit switches, selector switches, push buttons, photoelectric switches, and TTL-compatible devices. This module is designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and transient-free, "clean" switching.
