Squirrel Data Logger Module M28A

Inputs:

• 8 Pulse count or 8 Frequency/Count
• Pulse count:
•      Counts all voltage or volt-free signals over the programmed interval
•      Maximum rate for voltage signals (4 to 15 volts) is 2KHz, pulse width =5µs
•      Maximum rate for volt-free contacts is 100Hz (contact debounce active)
• Frequency/Count
•       Frequency - counts all pulses over one second, presented as frequency
•      Count - presents the sum of pulses measured over the logging interval
•      Voltage signals only (4 to 15 volts), maximum frequency is 65 kHz, pulse width = 5µs

Connectors:

• Use the 4 way ST plug per 2 x inputs.
