ML-OI-AX-DI, Option board to add four more digital inputs/counters

data logger counter & totalizer The ML-x17 data logger is standard provided with 3 digital inputs, but some applications might require some more.

The ML-OI-AX-DI option board adds four more digital inputs that can be used to monitor on/off states and/or totalize pulse counts up to 10kHz.

A little coin cell battery makes sure that counter values are kept in case of power outage to the board. The totalizers can manualy be set to 0 or any other value through the terminal interface of the ML-x17.

Note: To record pulse rates (e.g. a wind speed), on-time or trigger actions, please use the digital inputs of the ML-x17 instead.
