AMETEK 5400 Plug In Style Solid State Relay - Manual (Page 2)

TYPICAL APPLICATIONS
Diagrams at right illustrate basic details of typical
application in which Series 5400 Relays are used as
original equipment components to provide fail-safe
control by de-energizing the load in event of power
of relay failure.
In Diagram 1, Type 5400-C Relay is used in direct
operation to provide automatic pump down control
for dehumidifiers, sumps or any other product
requiring control of a liquid at a given high-level set
point.
In Diagram 2, Type 5400-D Relay is used in inverse
operation to provide pump-up control for
carbonators, humidifiers, purification stills, etc.
where liquid must be kept above a low level set
point.
In Diagram 3, Type 5400-A Relay is used in direct
operation to provide high-level alarm.
In Diagram 4, Type 5400-B Relay is used in inverse
operation to provide low-level alarm.
ACCESSORIES
The 5400 relays require a standard 8 pin octal base
for mounting. In addition a hold down strap is also
available to secure the 5400 the relay to the octal
base in vibration environments.
INSTALLATION NOTES
Because Series 5400 Relays feature a low voltage,
low current sensing circuit, inexpensive small
gauge lead wires may be used between relays and
electrodes, sensors, or pilot switching devices.
Shielded cable is not required, and lead wires do
not have to be isolated from other wiring. Also, in
many level control applications, a common
electrode is not required so long as a good,
dependable metallic ground return from the relay to
the liquid is provided. The length of the control
wires, between the electrodes and the Series 5400,
are dependent on two factors, the control wire
configuration and the sensitivity setting, see
reference chart to the right.
