MINT – IO
REF NO: m25A/om/101
Issue No: 11
4. IO modules:
4.1 mINT
– 16DI – Digital Inputs with counters:
4.1.1 Description:
The IO-16DI module is a 16 channel digital input module. The inputs are
isolated from the logic by bi-directional O/pto-couplers. The common is
connected internally to either the (-) volts or (+) volts. The inputs have internal
counters associated with them. These counters are 32 bit Counters allowing a
count value from 0 to 4294967295. The count value can be cleared by writing
a zero to the associated registers or preset to any other value using the same
method.
