Plug In Style Liquid Level Control Relay
COMPACT PLUG IN STYLE RELAY
B/W Series 5400 Relays were developed especially for use as safe, reliable,
economical original equipment components in many different types of
commercial and industrial products.
Designed to operate from electrodes or probes contacting conductive liquids,
they are ideally suited to level control applications in such products as
vending, dispensing, ice-making machines, water softeners, dishwashers,
and coffee makers, plus many type of operating equipment in the food, drug,
dairy, brewing, distilling and chemical processing industries.
In addition, Series 5400 Relays have a low energy sensing circuit with a lock-
in holding feature that permits operation over a range of levels, or from
momentary contact pilot devices such as float, actuators, etc. Thus they are
equally suitable for use as original equipment components in many products
and systems that require monitoring and control of such process variable as
temperature, pressure, humidity, flow, voltage and current, etc.
OTHER FEATURES AND ADVANTAGES
• UL Recognized Component File No. E61377
• CUL File No. LR 33434
• Choice of direct or inverse operation to provide fail-
safe control. In direct operation, load relay is
energized when the low voltage ac sensing circuit
is completed. In inverse operation, load relay is
de-energized when the low voltage ac sensing
circuit is completed.
• LED indicates when relay is energized.
• Relays will operate reliably when mounted in any
position required to meet a complete range of
application design requirements.
• Relays will operate over ambient temperature
range from –10° + 131°F (-23° to 55 °C).
• User adjustable sensing resistance.
• Rugged octal plug-in housing.
• Heavy-duty
internal
construction.
