Product Information
Description
Electro-Sensors' SA420 Digital Signal Conditioner provides an analog signal directly proportional to the speed of a rotating shaft. The 0-10 Vdc and 4-20mA output signals can be sent to a digital display, PLC, chart recorder, loop controller, drive speed controlleror other control/monitoring device. The wide voltage range and wave shape flexibility of the SA420's sensor input circuitry enables it to translate input signals from Hall Effect sensors, proximity switches, magnetic sensors, and a wide variety of other pulse generator devices, into analog outputs. The standard SA420 system includes the SA420 DIN rail mount module, a 906 sensing Head and a 255 Pulser Disc. Electro-Sensors' products bring efficiency and safety to your operations by preventing machine damage, product waste and costly downtime.
