The TimeMark 2611-120 is a duplex alternating controller for a 120 V AC/DC supply. Its float or pressure switches bring two loads on one after the other, and it drops them all together when the off switch opens; the lead load alternates every cycle, so the run time evens out.
Inputs: three control switches (STOP, LEAD, LAG) from L1. Selector switch: lead select: alternate, or lock the 1-2 or 2-1 sequence. Control switch fault detection. Supply tolerance: 90-130V (max 140V).
Output: 2 x SPST-NO (one per load), 10 A at 120 V AC resistive. Mounting: plug-in, on an 8-pin octal (TimeMark 51X120 socket) base. Indicator: 5 LEDs: STOP, LEAD, LAG switch status (red); LOAD 1, LOAD 2 (green). Approvals: UL Recognized (U.S. and Canada). It operates from 0 to +60 °C.
