Analog Output Module (4 Channels) - Honeywell ControlEdge 900 platform Hardware Planning And Installation Manual

Minimum Pulse Width: 2.25 μsec
n
Quadrature Counter: 32 bits signed
n
Quadrature Modes: For variable resolution there are three count
n
modes for the Pulse/Quadrature input: X1: rising edges of signal A
are counted (increment); falling edges of signal A (decrement) X2:
rising and falling edges of signal A are counted X4: rising and
falling edges of signals A and B are counted
Quadrature LEDs: Two LEDs indicate UP and DOWN direction of
n
counting.
