G4IAC5 G4 Digital AC Input Modules, 90-140 VAC, 5 VDC Logic, 20 ms Turn-On/Off

Description

Opto 22’s G4 AC input modules are used to detect on/off AC voltage levels. Each module provides up to 4000 volts of optical isolation (transient) between field inputs and the logic output of the circuit. All AC input modules are designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and transient-free "clean" switching. Typical applications for AC input modules include sensing the presence or absence of voltage, and sensing contact closure from sources such as proximity switches, limit switches, float switches, selector switches, push buttons, toggle switches and thermostats. Input voltage range: 90-140 VAC or VDC. Input current at maximum line: 5 mA. Isolation, input-to-output (transient): 4000 V at 1 ms, 1500 V at 1 minute. Turn-on time: 20 ms. Turn-off time: 20 ms. Input allowed for off-state: 1.4 mA, 40 V. Nominal output supply voltage: 5 VDC. Output supply voltage range: 4.5-6 VDC. Output supply current at nominal logic voltage: 12 mA. Input resistance (R1 in schematic): 28 K ohms. Control resistance (Rc in schematic): 220 ohms. Output voltage drop: 0.4 V at 50 mA. Output current (sinking): 50 mA. Output leakage with no input: 100 microamps at 30 VDC. Transistor: 30 V breakdown. Operating temperature: -30 to 70 degree C. Storage temperature: -30 to 85 degree C.
