Digital Inputs
Technical Information
There are four digital inputs on the I/O board. One of the inputs is dedicated for
the Enable and cannot be configured. The other three inputs can be configured.
Digital Input 1 is 24VDC and Digital Inputs 2 and 3 can accept a 12…24VDC
signal. There is a 24VDC power supply on the I/O board to supply power for
those inputs.
Digital Inputs 2 and 3 are high speed digital inputs with a maximum input
frequency of 350 kHz.
