• Opto 22 G4 I/O module.
An Opto 22 G4 I/O module is a device designed to provide high noise rejection,
the ability to safely connect high voltage equipment (either AC or DC) to your
Matrox camera using opto-isolation, and transient-free "clean" switching.
• PNP-compatible PLC devices.
PNP-compatible PLC devices include all forms of external devices that are
programmable logic controllers with PNP transistor types. A PNP-compatible
PLC device has an input that is enabled when it receives a voltage (sourcing input).
• Pulse.
A pulse is a sudden change of a signal's state (for example, from OFF to ON).
• Pulse-width modulator.
Pulse-width modulator (PWM). A specialized timer that generates a pulse-train,
whose duty cycle is proportional to the intensity of a connected light (such as, a
ring LED).
• Transistor-transistor logic (TTL) devices.
Transistor-transistor logic devices expect the connected device to provide the
necessary voltage. Note that a TTL device can be used as either an input or an
output device.
• Wire-terminal.
A wire-terminal is a connector designed to receive a single wire that will carry a
signal. For example, an output wire-terminal is designed to receive a wire that will
carry an output signal to your third-party device.
