GENERAL DESCRIPTION
The RLY7 is a three phase solid state relay that switches load currents up to
25 A. The unit features a zero voltage turn-on detector to minimize radiated RFI
when switching. An internal snubber guards against false triggering of the
output related to high dv/dt applications. A low level DC control signal of 4 to
32 VDC is all that is needed for the switching operation. This unit, highlighted
by the inverse-parallel SCR output, provides a greatly increased operational life
over a mechanical relay by avoiding the usual relay contact problems such as:
arcing, bouncing, and mechanical failure.
The RLY7 can be directly controlled by logic/SSR drive output or sourcing
output of Red Lion Controls products.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit.
