The SNAP-AIRATE-HFi rate-input module and the SNAP-AOD-29-HFi module with pulse-width modulation (PWM) and time-proportional output (TPO) are designed for test engineers, technicians and others working with high-speed machinery, equipment test beds and other applications that monitor high-frequency analog signals and rapidly switch digital outputs in response to changing analog value. Both modules are used with Company's SNAP PAC System, which includes programmable automation controllers (PACs) and ethernet-based I/O systems. The SNAP-AIRATE-HFi analog input module connects to TTL, CMOS, and open-collector outputs, and is typically used for high-speed (up to 500 kHz) pulse scanning. The SNAP-AOD-29-HFi sends pulse-width modulated outputs to high-frequency transducers and can be used with test bed applications that simulate tachometer outputs.
