Onlinecomponents.com, an authorized distributor of Opto-22 products, feature the G4 DC input modules. The devices are used to detect on/off DC voltage levels. Each module can provide up to 4000 volts of optical isolation between field inputs and the logic output of the circuit.
All DC input modules except the G4IDC5K and G4IDC5D are designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and transient-free, “clean” switching. The G4IDC5K is a fast-switching module used to detect signals produced by photoelectric switches and TTL devices. The low-cost G4IDC5D is used for data acquisition.
The G4IDC5MA is a special module featuring a manual-on/ manual-off/automatic switch, ideal for diagnostic testing of control applications.
The G4IDC5-SW and G4IDC5-SWNC modules supply power to an external dry contact switch and sense switch closure (SW) or opening (SWNC).
