LOGIC INPUTS
Multiple contact-closures or ‘open-collector’ logic outputs may be wired in parallel to a single Logic Input (see diagram below). Logic
Outputs and contact-closures should be rated for at least 5 Volts / 1mA operation. Low-current / dry-contact closures are recommended
for reliability. Active output driver circuits should not exceed a signal range of 0~5 Volts DC, and should have a minimum pulse width of
100 milli-seconds. Logic Input impedances are approximately 10k ohms.
