BRX Do-More PLC High Speed IO
The BRX Do-More series of programmable logic controllers have built-in high speed inputs and outputs. Every CPU will have either 6 or 10 high speed inputs (HSI) available depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input counts per second that can be coming from devices connected to your PLC like an encoder. Every BRX CPU unit also has 2, 4, or 8 high speed outputs (HSO) available depending on the model. The outputs can send a frequency of pulses out up to 250Khz. Due to the speed of the IO, these functions available on the BRX PLC will operate asynchronously with the PLC scan time. We will be looking at sending an output of pulses at different frequencies from our BRX PLC and inputting these back into the high speed inputs of the PLC. So our output will be wired back into our input. We will then display the frequency of the input pulses and the count. As a system integrator, this ability to send and receive high speed inputs and outputs can prove very useful to you in the field when commissioning your automation system. Let’s get started with the BRX Do-More PLC High Speed IO. More information can be obtained at our website.

Here are just a few. - Standalone PLC with built-in I/O - Built-in Data Logging - Communication ability - Ethernet Port, RS232, RS485, USB - support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet) - Built-in Analog input and output - Integrated motion control - High-speed counters - Powerful instruction set (Video of Instructions in software) - Ability to expand the system with a variety of modules - Part of the Do-More series of PLCs which use the same free software. (Do-More Designer) - Integrated simulator in the software capable of external communications for testing The BRX series of programmable logic controllers consist of four different units. They differ depending on the Inputs and Outputs built into the unit and if it has an ethernet port. No I/O Micro PLC unit – (BX ME) 10 Point Micro PLC unit – (BX 10/10E) 18 Point Micro PLC unit - (BX 18/18E) 36 Point Micro PLC unit - (BX 36/36E) These CPUs (Central Processing Units) are also known as MPU (Multi-Processing Units) because of the communication capabilities. https://www.accautomation.ca
