for the purpose of driving high energy loads.
This module serves as an interim digital interface
to switch high voltage devices at high currents
based on digital logic inputs. Each pair of output
contacts are individually isolated.
These modules are very easy to use. Removable
front-facing terminal blocks on the module’s
top and bottom greatly simplify field wiring.
Individidual channel LEDs indicate the output
state for convenient troubleshooting.
Rugged construction and high density design
combine for a very effective I/O solution. These
units are ideal for remote monitoring, distributed
control, or SCADA applications.
