Sensor

Inputs connected as follows:
The 'Input A' input is used for Frequency, RPM, Interval, Counter, Digital State and Mark output types. This can
take the form of a normally open or normally closed switch or relay contacts. The input resistor selection of pull
up or pull down can be selected to suit the input.
When in Quadrature output mode the 'Input A' and 'Input B' inputs are connected to the Quadrature outputs A
and B respectively.
The T24-PA can also be used with a repetitive sine, square or pulse wave signal source such as a signal generator
or RPM sensor. The amplitude should be between 0.8 V and 6 V peak.
A maximum of 50 mA can be drawn from 'Excitation' (User selectable for 3 V, 5 V or 12 V) to power a pulse
generating sensor.
Reset Count is a 'volt-free' contact input. This can be used to reset the count input to zero. To activate connect
'Reset Count' to GND.
