SCR sensors working with AC Voltages
SCR Series Sensors
An issue was found with AC voltages below 22.8VAC
Any SCR units that have been shipped since 1 March 2012 will be fine with the full AC supply range (as per their datasheet), however we had an issue with older units that require the AC supply to be above 22.8 Volts to ensure there are no problems.
DC supply voltages operate correctly on all SCR sensors.
