All-O-Matic SL-90DC PRO Slide Gate Opener, 24V DC Brushless with Battery Backup

PRO means the ALL-BLDC PRO control board. It adds an LCD menu with on-board diagnostics, digital force and auto-close adjustment, wireless primary/secondary pairing, partial open, programmable aux inputs, a 7-day timer, a cycle counter and a USB port for firmware updates and diagnostic data. The motor, gearbox, 1,600 lb / 50 ft rating and dimensions are the same as the earlier SL-90DC.

FP stands for foot pedal. The mechanical foot-pedal release is standard on the SL-90DC. To open by hand, step on the pedal, latch it to the side and push the gate. A kill switch stops the motor from running while the pedal is down, even with power on.

It is rated for slide gates up to 1,600 lb and 50 ft long. For heavier gates, All-O-Matic's SL-100DC PRO is rated to 2,000 lb and the SL-150DC PRO to 3,000–4,000 lb.

Two 12 V 7Ah batteries are included. All-O-Matic rates them at about 150 cycles on a 1,000 lb gate and up to two weeks of standby. A DIP switch picks fail-safe (the gate opens before the battery runs flat) or fail-secure (it runs until the battery is low, then stays closed). An AUTO OPEN setting opens the gate about 40 seconds after a power loss, for fire-department requirements.

Yes. The board has a SOLAR input with an MPPT regulator. It needs at least a 24 VDC, 40 W panel and can charge from up to 80 W. With two 14Ah batteries, a receiver and two monitored sensors, All-O-Matic estimates about 20 cycles a day. The panel and the larger batteries are not included, and systems over 80 W need an external charge controller.

Yes, one AOM Red Eye photoelectric sensor comes with the SL-90DC PRO. UL 325 requires monitored protection for every entrapment zone, and the operator won't run automatically without it, so many driveways need another photo eye or an edge. The board takes normally-closed or 10K monitored devices from most brands.

Any monitored normally-closed device powered from the MON +24VDC terminal works, and the PRO board also accepts 10K-terminated devices. The manual has wiring for Enforcer, Allen-Bradley, Omron, EMX and Miller Edge models. AUX INPUT 1 and 2 can be set as extra MON_OPEN or MON_CLOSE inputs when one device per direction isn't enough.

No. It takes an external 3-wire receiver on the terminal strip outside the control box, or a 4-wire 12/24 VDC receiver. The radio power jumper ships set to 12 VDC, so move it to 24 VDC for receivers that need 24 V.

There is no built-in Wi-Fi or app. The PRO board's wireless feature only links two operators (primary/secondary), and its USB port is for firmware and diagnostic data. Phone control needs a third-party controller wired to the board's inputs; All-O-Matic has a video on the Nexx NXG-200.

The rated operating range is -40°F to 160°F. Batteries lose capacity in the cold, so solar or high-cycle sites in cold climates should use larger batteries, as the manual advises.

115 or 230 VAC single phase, set with a voltage switch on the EMI board, on a dedicated 20 A circuit with a proper earth ground. Size the wire run using the current-draw and wire charts in the manual to avoid voltage drop.

It is pad-mounted on a concrete footing (about 24" x 24" in the manual drawing) with four 1/2" x 3-1/2" red-head anchors, set 4" above grade where possible. It can be front- or rear-mounted relative to the gate. A pedestal can be used instead of a pad; it is sold separately.

Yes. The ALL-BLDC PRO supports wireless (8 channels) or hardwired primary/secondary linking, and accessories can connect to either operator. Leaf delay can be set for one direction.

The PRO board supplies up to 750 mA at +12 VDC and 750 mA at +24 VDC for loop detectors, keypads and similar devices. If your accessories draw more, add a separate power supply.

7 years residential and 5 years commercial on circuitry, motor, gearbox and workmanship. Labor and shipping are the owner's cost. The registration card must be mailed within 30 days, or coverage drops to 1 year on parts only.

The SL-45DC PRO is a smaller unit (800 lb / 30 ft) with a planetary gearbox, push-open release and a 5-year residential warranty, and it is listed for UL Classes I & II only. The SL-90DC PRO doubles the capacity (1,600 lb / 50 ft), adds the foot-pedal release, is listed for Classes I–IV and carries 7 years residential / 5 years commercial.

Padlock tabs come only with the SL-45DC. For the SL-90DC, a lock kit is sold separately.
