The AIFO-200 is an interface device used between an analog signal and a frequency-input device typically used in applications where a process is monitored by a transducer, PLC, PC, or some other device that provides a 0-10 VDC or 4-20 mA signal. With the AIFO-200, this signal is converted to a frequency and can be used to provide the lead signal to a closed loop controller, or as the input to an electronic counter, tachometer or PLC system. Zero and span potentiometers are provided to calibrate the output frequency to your requirements.

Digital Signal Conditioner

• DIN rail mount enclosure
• 0-10 VDC and 4-20 mA outputs
• Input frequencies to 10 kHz, 115 VAC standard,
220 VAC, 12 / 24 VDC optional
• LCD display for field adjustable calibration
• ETL approved to applicable UL and CSA standards

The SA420 interfaces with a wide variety of sensors and provides an analog signal directly proportional to the speed of a monitored shaft. The 0-10 VDC and 4-20 mA outputs can be sent to a chart recorder, digital display, PLC, loop controller, drive speed controller, or any other control or monitoring device. The wide voltage range and wave shape flexibility of the SA420 input circuitry allow it to translate signals from Hall Effect sensors, proximity switches, magnetic sensors, and a wide variety of other pulse generators, into analog outputs.
