The ARP41 is an alternating relay designed for applications requiring equal runtime between two motors. It features an SPDT 8-pin configuration and a rotary switch to select alternation mode or lock operation to a specific load, with LEDs indicating relay status. The unit operates on 120VAC, with an electromechanical relay rated at 10A resistive at 120/240VAC and 1/3 hp. It supports front panel mounting with the BZ1 accessory or 35 mm DIN-rail mounting via the NDS-8 socket. Dimensions are 60.7 mm high, 45.2 mm wide, and 81.3 mm deep, weighing approximately 159 g. Input voltage tolerance is ±20% to +10% for 120VAC, with operation at 50/60 Hz. Isolation voltage is ≥1500V RMS, and mechanical life is 1 × 10⁷ cycles. It operates between -20°C and 60°C and is stored between -30°C and 85°C. No debounce time delay is present.
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. This versatile series may be front panel mounted (BZ1 accessory required) or 35 mm DIN rail mounted with an accessory socket. Operation Alternating: When the rotary switch is in the “alternate” position, alternating operation of Load A and Load B occurs upon the opening of the control switch S1. To terminate alternating operation and cause only the selected load to operate, rotate the switch to position “A” to lock Load A or position “B” to lock Load B. The LEDs indicate the status of the internal relay and which load is selected to operate.Note: Input voltage must be applied at all times for proper alternation. The use of a solid-state control switch for S1 may not initiate alternation correctly. S1 voltage must be from the same supply as the unit’s input voltage (see connection diagrams on datasheet). Loss of input voltage resets the unit; Load A becomes the lead load for the next operation.Duplexing (Cross Wired): Duplexing models operate the same as alternating relays and when both the Control (S1) and Lag Load (S2) Switches are closed, Load A and Load B energize simultaneously.The DPDT 8-pin, cross-wired option, allows extra system load capacity through simultaneous operation of both motors when needed. Relay contacts are not isolated.
