The 1761-L10BXB is an Allen-Bradley Programmable Logic Controller (PLC). This controller is intended for implementing micro and small automation requirements with integrated 1K EEPROM memory which is internally allocated for 737 instruction words and 437 data words. This controller comes with a compact and small form factor design and supports DIN rail or panel mounting. The 1761-L10BXB is a compact controller that comes with a total of Ten (10) embedded I/O channels which are comprised of Six (6) 24 VDC inputs, Two (2) 24 VDC sourcing outputs, and Two (2) relay outputs. In addition, this controller comes with an RS232 communication interface that may be used with Allen-Bradley manufactured cables for establishing communication with the device. These cables include 1761-CBL-PM02 Series C, 1761-CBL-HM02 Series C, 1761-CBL-AM00 Series C, 1761-CBL-AP00 Series C, 1761-CBL-PH02 Series A, and 1761-CBL-AH02 Series A, Furthermore, compatible cables for connection of Operator interface Module includes the 2707-NC8 Series B, 2707-NC9 Series B, 2707-NC10 Series B, and 2707-NC11 Series B cables. The 1761-L10BXB is powered by an external 24 VDC supply voltage with an effective voltage range of 14-30 VDC with power supply usage of 5 Watts. It is capable of withstanding an inrush current of 4 Amperes at a duration of 30 Amperes. It is designed to perform up to 50,000 power cycles, minimum.

The Allen-Bradley 1761-L10BXB is a part of the MicroLogix 1000 family of controllers. It is a small programmable controller that can fit in a small panel space. For communication, it has a built-in RS-232C port for DF1 protocol, Point-to-point, DH-485, DeviceNet, and EtherNet/IP communication. These communication types support direct connection, half-duplex slave protocol for SCADA applications, program upload, and download, and peer-to-peer communication. It has more than 65 instructions for applications like a high-speed counter, sequencer, and shift registers. It can run programs and operate in up to 5 different languages. The 1761-L10BXB controller has 10 I/O with 24V DC sink/source 6 inputs, 2 contact outputs, and two 24V DC outputs. It has a real input power of 5W at 24V DC. It has a 1500V AC isolation voltage and a 1K-word EEPROM. Its program scan time is 2ms and its I/O scan time is 0.21ms. It has a maximum of 32 counters and 40 timers. The 1761-L10BXB comes with a master control relay safety feature. It is installed using a DIN rail or mounting screw method with adequate spacing in the enclosure for heat dissipation. It is intended for use in a category II non-hazardous industrial environment with a 0 - 55 deg. C (32 - 131 deg. F) operating temperature and a 20g maximum operating shock.
