1760-L20BBB-EX

The Allen-Bradley 1760-L20BBB-EX is a Pico Programmable Logic Controller (PLC). This miniature PLC device is ideally used for micro and small automation requirements as it comes with a small form factor and built-in I/O channels such as with Twelve (12) 24VDC inputs with Four (4) inputs (I7, I8, I11 and I12) configurable as 0-10VDC analog inputs and Eight (8) MOSFET output channels. This controller comes with embedded Real-Time clock (RTC), user display and keypad interface.

The 24 VDC input channels has an ON-state voltage signal of 15 to 28.8VDC for inputs I1 to I6, I9 to I12, and R1 to R12 while inputs I7 and I8 has 8-28.8VDC ON-state voltage signal. Conversely, the Off state voltage signal range is < 5.0V dc (I1 to I12 R1 to R12).

The configurable analog input channels such as inputs I7, I8, I11, and I12 are compatible for 0-10VDC input signal range. Each channel has 0.1VDC resolution with input impedance of 11.2K ?.

The output channels are rated 24VDC with permissible range of 20.4 to 28.8V dc and residual ripple of ?5%. It also comes with reverse polarity protection.

The 1760-L20BBB-EX has a nominal power supply requirement of 24VDC with permissible voltage range of 20.4-28.8VDC with residual ripple ?5%, nominal input current of 140 mA at 24VDC and nominal Power Dissipation of 3.5 Watts.

Pico controllers can be defined as an electronic control relay with built-in real-time clock functions, and counter, timer, and logic modules.

The 1760-L20BBB-EX Pico controller is capable of performing a variety of tasks particularly in the micro and small automation field. The 1760-L20BBB-EX Pico controller supports programming using Ladder programming language.

The 1760-L20BBB-EX supports DIN rail mounting that should follow the recommended spacing requirements. Additionally, it supports horizontal and vertical mounting orientation.
