Specications
The Model 350
is a heavy-duty voltage monitor. This product
should be used when high current relays or dual
contacts are required, or 480V controls are used.
Since the Model 350 uses heavy-duty relays, it
comes in fixed voltage range models rather than a
dual auto-ranging version like the Model 250.
The Model 350-200 has a 15A general purpose
contact. The Model 350-400 provides a SPDT (Form
C) relay rated to switch up to 600V, allowing the
use of 480V controls, eliminating the need for a
control power transformer to step the voltage
down to 120-240V. Several DPDT (two Form C
contacts) relay models are also available.
The Model 350 microcontroller-based family
of products are low cost yet highly advanced
solutions to heavy-duty problems. The Model
350 includes advanced single LED diagnostics.
Five different light patterns distinguish faults and
normal operating conditions. Other options such
as high voltage trip and adjustable restart delay
are available.
For more information see:
See Appendix A, page 68, Figure 7 for dimensional
drawing.
See Appendix B, page 75, Figure 20 for typical
wiring diagrams.
