The Allen-Bradley 1761-L32BBB is a programmable controller. Its power supply ranges from 20.4 to 26.4 Volts DC and it has 32 input and output points. It also comes with a compact size. The 1761-L32BBB needs little panel space compared to other similar programmable controllers. The 1761-L32BBB controller can connect to a peer-to-peer network with its RS-232 and DH-485 ports. It can also use the DeviceNet interface (DNI) for high-speed and reliable communications. The 1761-L32BBB can run ladder logic on a variety of software in its 1-KB memory.
The 1761-L32BBB’s hand-held programmer (HHP) has six languages built in. This controller is also fast with an execution time of only 1.56 milliseconds and a throughput of 1.85 milliseconds for running a typical 500 instructions program. The controller’s input options include AC, DC or analog inputs for the current and voltage and the output options include relay, TRIAC, MOSFET and analog outputs for the current and voltage. The 1761-L32BBB controller has 12 basic logic instructions, 43 applied control instructions and 14 advanced application-specific instructions for a variety of functions.
