AMETEK 5400 Plug In Style Solid State Relay User Manual

Series 5400

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.

Plug In Style Liquid Level Control Relay

COMPACT PLUG IN STYLE RELAY

B/W Series 5400 Relays were developed especially for us e 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 lockin 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 equipme nt components in many products and systems that require monitoring and control of such process variab le as temperature, pressure, humidity, flow, voltage and current, etc.

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 po wer 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 bet ween 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.
