The inputs are conditioned using Schmitt trigger buffers. If an input is configured as edge triggered, the triggering pulse must have a duration of at least 1ms (one software scan) to guarantee acceptance by Mint. The use of shielded cable for inputs is recommended.
Active high: connect +24VDC to the input and 0V to pin 9 (CREF).
The digital inputs will be active when a voltage of +24VDC (greater than 12VDC) is applied to them and will sink a current of approximately 11mA each.
Active low: connect +24VDC to pin 9 (CREF) and 0V to the input.
The digital inputs will be active when grounded (<2V) and will source a maximum of 11mA each.
Note: Sustained input voltages above 28V will damage the inputs.
