MODEL 261 series Alternating Relays  Solid-state Reliability  Heavy-duty Contact Rating  Optional Load 1-Load 2 Toggle  UL Recognized; CSA Certified SPECIFICATIONS DESCRIPTION MODEL 261 x (T) - xxx The Model 261 series Alternating Relay is designed Supply Voltage 12V AC/DC 24V AC/DC 120V AC/DC 240V AC/DC for duplex pumping systems where it is desirable to Voltage Range 10 - 14V 20 - 28V 90 - 130V 180 - 250V equalize pump run time. The solid state alternating Max Voltage 15V 30V 140V 260V circuit drives an internal electromechanical relay. A continuous power source and control switch are Supply Current 0.1A 0 . 05A 0 . 01A 0.01A required. Control Current 0.001A Operating Duty Continuous The control switch (float, pressure or other isolated Min. Cycle Time 100ms contact) is connected between the L1 terminal and the Contacts 10A at 120VAC resistive control terminal. Each time the control switch is opened Expected Relay Life Mech: 10 million operations the output contacts will change states. Indicator lights Elec: 100,000 operations at rated load on the case show the internal relay status. Operating Temp 240V models: - 40º to +131º F On the optional toggle switch versions, the toggle switch All other models: - 40º to +140º F is set to the NORMAL position. Setting the switch to Humidity Tolerance 0 - 97% w/o condensation Load 1 or Load 2 will lock the relay in position, Mounting 261D: 11-pin socket * preventing alternation. 261S or 261DX: 8-pin socket ** Enclosure Material ABS plastic 4.3 oz.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE. GENERAL SAFETY POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 261. ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING. THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL. Installation Instructions TYPICAL APPLICATION: 261D INSTALLATION 9 Connect wiring to the socket as indicated in the 10 11 following examples. 3 RL2 2 The Model 261 series Alternating Relays are extremely 1 RL1 6 versatile and can be used in many other configurations 4 besides those shown. Any type of switch (float, pressure, etc.) can be used as the control switch; 8 however, it must be connected as shown (from L1 to the control input) or the alternator will not function properly. On Toggle Versions: For normal operation (alternating L1 loads) set the toggle switch on the top of the case to the Control “normal” position. Setting the toggle switch to either “1” or “2” will lock the alternator in that position.
