Alternating

• Two-, Three-, and Four-Load Units Available
• Automatic Alternating or External Clocking
• LEDs Show Position Of Output
• Plug-in or Surface Mount
• In the Event of a Power Failure, Relays Will Return to Their Quiescent State and Continue Sequencing Loads One-at-a-Time

The Alternating Relay is used in multiple-load installations to assure equal run time on all loads. They also allow for the addition of more capacity in the event of excess load requirements. The Alternating Relay provides equal run time on two or more loads by alternating the sequence in which the loads are allowed to start up. In each case, the alternating action is initiated each time the control switch across designated terminals opens. The control switch may be a float, a thermostat, a pressure switch, or a timer contact.

• Provides equal run time for two motors
• Alternating or electrically locked operation
• Low profile selection switch
• 10A output contacts
• LED status indication

The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows selection of alternation of either load for continuous operation. LED'S indicate the status of the output relay.

• Alternates Between Two Loads
• Solid State Reliability
• Compact Size
• Debounce Time Delay
• SPDT or Cross Connected

Model ALT alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps.

• One or two switches
• Control Duplex Loads
• Range of Control voltages

These alternating relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads. This alternating action is imitated by a control switch such as a float switch, manual switch, timing relay, pressure switch, or other isolated contact.

• Optional low profile selector
• 10 Amp SPDT or DPDT Output

• Multiple Functions Available
• 0.1 Seconds~ 1000 Hours
• SPDT Output Contacts
• Microcontroller Circuitry
• UL; CSA; CE Approvals

The KRPS is a factory programmed module available in any 1 of 10 functions and measures only 2 inches square. The KRPS offers a wide range of fixed or adjustable time delays. Modules are manufactured and placed in stock. When an order is received, the function software is added making the modules complete. This approach provides fast delivery on all part numbers. The output relay contacts offer a full 10 A rating with complete isolation. Its microcontroller timing circuit provides excellent repeat accuracy and stability. Encapsulation protects against shock, vibration, and humidity. The KRPS Series is a cost effective approach for OEM applications that small size, isolation, accuracy, long life, and factory stock modules.

• High, low and out-of-sequence alarms
• Variable time delay/lag pump delay
• Separate pump stop
• Pump alteration with or without a non-alternating pump
• Jockey or emergency pump
• Deplex, triplex or quadplex pump modes
• Pump-up or pump-down functions
• External silence, reset and alternation configuation
• Five-channel relay

SymCom’s Pump Control™ Model PC-105 is a five-channel pump controller designed to handle multiple pump applications. Alternatively, it can operate as a 5-channel switch. The PC-105s control functions support all of the popular industry-standard multi-pump configurations. Using the built-in DIP switches, individual pumps can be disabled when taken out of service for repair or maintenance.

• Three Switch Input
• Control Triplex Loads
• Range of Control voltages

The ATP Series triplexors are used in three load applications requiring both the optimization of load usage by equalizing the run time of multiple loads and additional capacity in case of excess load requirements. All versions offer an indication of a switch failure; LEDS will flash if any switch closes out of sequence.

• Plug-in enclosures
• Input switch failure

• Duplexor that Detects Input of Float Switch Inputs and Determines Outputs
• Loads Remain Energized with Lag and Lead Switches Open
• ARD Series has 3 Position Selector Switch To Lock It Into Normal Duplexing Action, 1-2 Sequence or 2-1 Sequence
