Impulse COUNTERS
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.
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
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.
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
