User¨s Manual - Series MAG983-X
The MAG983-X is a series of impulse counters with 6
digits for panel mounting. The main input channel for
impulse counting is defined as «INPUT1», and the
additional input channel defined as «INPUT2» has a
variable function depending on the model selected. All
units can «RESET» from frontal push button and also
from rearside terminal for mechanical contact.

Impulse COUNTERS
Model MAG983-1
Impulse counter with Inhibit Control
«INPUT1» Input for impulses
«INPUT2» Control for Inhibit
Note .- «INPUT2» at negative logic, activates inhibit
Model MAG983-3
Impulse counter with Add/Substract inputs
«INPUT1» Impulses to ADD
«INPUT2» Impulses to SUBSTRACT
Model MAG983-2
Impulse counter with Add/Substract control
«INPUT1» Input for impulses
«INPUT2» Control for ADD/SUBSTRACT
Note .- «INPUT2» at negative logic SUBSTRACTS
Model MAG983-4
Impulse counter for Quadrature (Encoder)
«INPUT1» Impulses from encoder CHANNEL-A
«INPUT2» Impulses from encoder CHANNEL-B
The reading of the instruments can be scaled activating
scale factors, together with the position of the decimal
point. By default, all units are configured as :
1 impulse = +1
Signal type NPN
Without decimal points
If a different configuration is needed, request your needs
with the order, or see instructions on section 8 for self
configuration.
