Auxiliary Relay Contacts
The auxiliary relay contacts, pins 6 & 7, provide a way to cascade units or to
provide confirmation feedback to a central controller. When the switched
receptacles are on, the aux relay contacts are closed. There is a 1 second delay
before the aux relay closes which gives time for the SurgeX Inrush Current
Elimination (ICE™) circuit to operate. This short delay in combination with the
SurgeX ICE™ makes it unnecessary to sequence the power to several large loads
(such as amplifiers) because of inrush current. SurgeX RT products, when
cascaded, can turn on a bank of large amplifiers with no inrush current, and
therefore no risk of blowing a circuit breaker.
To cascade two or more RT products, connect the aux relay contacts of one unit to
the contact closure input of the next unit. To provide confirmation feedback,
connect the aux relay contacts to an input on the central controller.
The relay contacts are rated for 1 amp at 30 V DC.
