9. Input/Output Specification
Digital Inputs
NPN/PNP
Jumper congures all inputs with either pull-up for NPN (contact closes
to 0V) type sensors, or pull-down for PNP (close to V+) type sensors
Logic Level 0: 0V to +1V maximum
Logic Level 1: +2.0V to +30V maximum
Latched Inputs:
Triggered by user programmable positive or negative edges, stays true
until acknowledged
Counter Inputs:
User programmable – counts positive or negative transitions, up to
250Hz count rate
16-bit (65335 count) or 32-bit (4.2 billion count) counters
Counter values persist over power-off periods
