Why the 1763-L16BWA Belongs on Your Shortlist
Small-scale automation demands a controller that fits tight panels, handles mixed signals, and keeps running. The Allen-Bradley 1763-L16BWA from the MicroLogix 1100 series delivers exactly that. This programmable controller packs 10 digital inputs, 2 analog inputs, and 6 relay outputs into a compact housing measuring 3.5 x 4.33 x 3.43 inches. With an LCD display and dual communication ports, it gives operators local visibility and network reach without extra hardware.

| Memory | Non-Volatile Battery Backed RAM |
| Display Type | LCD |
| Dimensions | 3.5 x 4.33 x 3.43 inches |
Four of the ten digital inputs are high-speed, which matters when you count pulses from encoders or flow meters. The two analog channels accept 0-10VDC signals with 10-bit resolution, covering pressure, level, or temperature transmitters. Six individually isolated relay outputs handle switching loads directly, reducing external relay clutter.
Where This Controller Earns Its Keep
Oil and gas operations often need compact control at wellheads, metering skids, and small pump stations. The 1763-L16BWA fits these spaces. Its 24V dc sinking or sourcing inputs interface cleanly with field devices, while the relay outputs switch alarms, solenoids, or small motors. The Ethernet port supports SCADA and HMI connectivity for remote monitoring.
Water treatment and packaging lines also benefit. The analog inputs read tank levels or pressure transmitters, and the high-speed counters track production totals. With support for up to four expansion modules, you can grow I/O count as the process expands.
Integration and Wiring Notes
This controller offers one RS-232/485 port and one Ethernet port. When wiring into plant networks, confirm cable types and any needed gateways with your supplier. The analog channels work with 2-wire, 3-wire, and 4-wire transmitters, but the controller does not supply loop power. Belden #8761 cable is recommended for analog runs, with the drain wire grounded properly.
Relay outputs are rated for 10A load current with a mechanical life of 10,000,000 cycles. Turn ON and OFF time is 10 msec. The unit operates from -20 to 65 degrees Celsius at 5 to 95% non-condensing humidity.
Before You Buy
Verify your input power matches the 120 to 240 Volts AC range. Confirm your sensor types align with the 0-10VDC analog inputs and 24V dc digital inputs. Check that six relay outputs cover your load count. If you need more points, plan for expansion modules. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
