The ARP42S is a 120VAC DPDT alternating relay designed for applications requiring equal run time for two motors. It features a rotary switch that allows users to select between alternating operation or locking the relay to a specific load. The relay includes LED indicators to show the status of the output relay and which load is currently engaged.
This model can be mounted using an 11-pin socket and is compatible with both front panel and 35 mm DIN rail mounting options. It operates within a temperature range of -20°C to 60°C and has a mechanical life of 10 million cycles and an electrical life of 1 million cycles. The relay contacts are not isolated, and the unit requires continuous input voltage for proper operation. The ARP42S is suitable for applications where simultaneous operation of both loads may be necessary, as it supports duplexing functionality when both control switches are closed.
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.
