Surge and lightning
protection is becoming
a large consideration
for all Process
Control installations.
Lightning strikes,
static discharges and
induced voltages from
power lines are all
typical sources of
high voltage
transients and
overloads. Any low
voltage circuitry can
easily be damaged or
destroyed by these
voltages and so
Industrial Interface
have designed a range
of products to protect
Process Control
equipment form these
effects.
These devices
incorporate
three-stage protection
encompassing gas
discharge tubes,
voltage clamping
diodes and metal oxide
varistors. This hybrid
protection ensures
that any surge
currents are directed
instantaneously to
ground, while clamping
voltages on the output
terminals to suitable
levels. Once the surge
has subsided the
device will
automatically return
to normal operation. This design, combined with conservative ratings on the MOV's make these devices the maintenance-free alternative to existing surge protection devices. The following lists the options and datasheets available:
