ALTERNATING RELAYS SPDT & DPDT u For duplex loads u Can be used with one or two Control Switches u Control voltages of 12, 24, 120 & 240V AC u Compact plug-in design utilizing industry-standard 8 or 11 pin octal socket u 10A SPDT or DPDT Output Configuration u Optional low profile selector switch to lock in one sequence u 2 LED’s indicate relay status u 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 output relay contacts will change state, thus alternating the two loads. Two LED indicators show the status of the output relay. The Alternating Relays listed on this page can be used with one or two control switches & are available in either SPDT or DPDT output configurations (see "Typical Installations" on Page 53 for more information). For products with DPDT Cross-Wired output configurations to be used with one, two or three control switches, see Page 54. Each version is available with an optional three position selector switch. This allows the unit to alternate the two loads as normal, or lock the relay to one load or the other. By locking the Alternating Relay to one load, the other load can be removed for service without rewiring the first load for continuous operation. The selector switch has a low profile to prevent any accidental changes in status. with appropriate socket OUTPUT CONTACTS SPDT w/o Selector Switch SPDT w/ Selector Switch DPDT w/o Selector Switch DPDT w/ Selector Switch CONTROL VOLTAGE PRODUCT NUMBER 12V AC 24V AC 120V AC 240V AC ARP012A6 ARP024A6 ARP120A6 ARP240A6 8 Pin Octal 70169-D 12V AC 24V AC 120V AC 240V AC ARP012A6R ARP024A6R ARP120A6R ARP240A6R DIAGRAM 17 12V AC 24V AC 120V AC 240V AC ARP012A2 ARP024A2 ARP120A2 ARP240A2 11 Pin Octal 70170-D 12V AC 24V AC 120V AC 240V AC ARP012A2R ARP024A2R ARP120A2R ARP240A2R DIAGRAM 18 n See Page 58 for Sockets & Accessories. 800-238-7474 www.macromatic.com whats-up@macromatic.com 52 WIRING/SOCKETn ALTERNATING RELAYS SPDT & DPDT Application Data & Dimensions Application Data Voltage Tolerances: +10%/-15% of control voltage at 50/60Hz.

When the Control Switch closes, it energizes the first load (M1). The red LED marked “LOAD A” glows. As long as the Control Switch remains closed, M1 remains energized. When the Control Switch opens, the first load (M1) is turned off and the Alternating Relay toggles to the LOAD B position. When the Control Switch closes again, it energizes the second load (M2). The red LED marked “LOAD B” glows. When the Control Switch opens, the second load (M2) is turned off, the Alternating Relay toggles back to the LOAD A position, and the process can be repeated again. On relays with DPDT contacts, two pilot lights can be used for remote indication of LOAD A or LOAD B status. To eliminate any bounce condition of the Control Switch, the addition of a second switch (OFF) along with two auxiliary contacts is recommended as shown in Figure B.
