1762-L40AWAR | Allen-Bradley | MicroLogix 1200 PLC with 24 AC Inputs and 16 Relay Outputs
The 1762-L40AWAR is an Allen-Bradley MicroLogix 1200 Programmable Logic Controller. It runs on 120 to 240 VAC supply. It has 24 AC inputs and 16 relay outputs. Relay contacts are rated 24-125 VDC and 120-240 VAC, with a 20,000,000 cycle mechanical life. One 8-pin mini-DIN port supports RS232 DF1, plus a dedicated programming port. Both ports speak DF1, DH-485, ASCII, and Modbus. The unit controls loads up to 1440 VA. It fits panel builders and plants that need a compact all-in-one controller for AC field devices.

FAQ
Q: Can the 1762-L40AWAR talk to power meters without a gateway?
A: Yes. The serial port supports Modbus master/slave. Point it at meters that speak Modbus RTU over RS232. Set baud, parity, and node address to match the meter. Use a shielded cable and keep runs short. This saves the cost of a protocol converter.
Q: My sensors pull low current. Will they read correctly on these inputs?
A: Check the OFF state leakage first. This unit produces at least 1.5 mA of OFF leakage. A two-wire sensor that stays on below that level can read as ON. Add a bleeder resistor or choose a sensor rated to sink more than 1.5 mA. Test one channel before you wire the full panel.
Q: What should I confirm before ordering a spare 1762-L40AWAR?
A: Check three things. First, your supply is 120-240 VAC. Second, your I/O count fits 24 inputs and 16 relay outputs. Third, your loads stay inside 1440 VA total. Send us your rack photo and wiring drawing. We verify the fit before shipment.
Q: Can I drive both 120V AC and 24V DC loads from the relay outputs?
A: Yes. Contacts are rated 24-125 VDC and 120-240 VAC. Keep each load within the contact rating and the 10A load current. Group wiring by voltage to reduce noise. Do not mix AC and DC on the same terminal block.
Q: How do you handle shipping and warranty on this unit?
A: We dispatch in 24 to 28 hours. We ship by FedEx, UPS, or DHL. Every controller carries a 12-month warranty. We test each unit before it leaves our warehouse. You can reach us at info@oiltechcontrols.com for order questions.
