External Event Input
> Event sensor: Two-wire interface suitable for measuring mechanial and electrical contact closures.
> Maximum input frequency: 1Hz (1 pulse per second)
> Lockout time: 500ms
> Minimum pulse width: 1ms (hardware debounce
> Input/output impedance: 100k
> Edge detection: Falling edge, contact closure, or Schmitt-trigger buffer
>Preffered swith type: Normally open. For maximum battery life, the event input should be used with its prerred swithc type. The logger will work with normally closed switches, but battery life will be compromised.
> Open circuit input voltage: Battery voltage; nominally 3.0 V
> Maxmum input voltage: Battery voltage +0.3V
> User connection: 24 AWG, 2 leads: white (+), black (-) |
