R66 Series Features • • • • For Duplex Loads Transient Protection LED Indicates Output Relay Status Compact 8−Pin Octal Plug−In Case (Includes RLY300 Series) Alternating, 10 Amp, AC, SPDT & DPDT Cross−Wired Contact Relays. D60 SPDT, 1 Form “C” .200 (5.08) Input Voltage L2 L1 4 Control Switch 5 6 3 2.900 (73.0) 2 7 1 8 Load A: Pin2 Load B: Pin8 OPERATION 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 initiated by a control switch, such as a float switch, manual switch, timing relay, pressure switch, or other isolated contact. each time the initiating switch is opened, the relay contacts will change state alternating the two loads. DPDT Cross−Wired 2 Form “C” 2.400 (60.96) Control Switch Closed Control Switch * Open 4 Lag Switch De−Energized De−Energized Alternating Relays with cross−wired contacts can operate as normal alternating relays when one control switch is used. If a second lag switch is used, the relay will simultaneously operate two loads on a first ON, last OFF basis.
