The inputs are conditioned using low pass RC filters and 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 MintMT. Voltages below 2V are considered as 0V. The use of shielded cable for inputs is recommended.
Active high: The digital inputs will be active when a voltage of +24VDC (±20%) is applied to them and will sink a maximum of 8mA each.
Active low: The digital inputs will be active when grounded (<2V) and will source a maximum of 8mA each.
Note: Sustained input voltages above 28V will damage the inputs.
