Do-more BRX Series PLCs

Do-more BRX Series PLCs utilize advanced control technology developed to tackle both straightfoward and complex applications in no time. This PLC series is loaded with hardware and software features that provide an extensive toolbox to satisfy even the most demanding projects. With four different form factors to choose from, built-in high-speed I/O (on select models), numerous IIoT features including an embedded Rest API, interchangeable communications port, on-board analog I/O, and many I/O expansion modules available, BRX PLCs are ideal for any application.

• The BRX M series is a simple (no built-in I/O) controller that can be used for a variety of purposes, including machine data logging and Ethernet networking.
• The BRX 10-point series includes all the standard features plus 10 built-in discrete I/O points (AC, DC and relay options available). With the exception of models with relay outputs, all of the on-board discrete I/O can be configured for current-protected high-speed functions up to 250 kHz.
• The BRX 18-point series has all of the benefits of the 10-point series plus an additional 8 discrete I/O points for 18 total. 14 of the 18 I/O points (on non-relay models) can be utilized for high-speed I/O applications up to 250 kHz.
• The BRX 36-point series takes I/O count one step further with 36 onboard discrete I/O points, 18 of which (on non-relay models) are capable of protected 250 kHz high-speed I/O.

BRX PLCs with built-in high-speed I/O can be used as an all-in-one PLC/motion controller. BRX "No I/O" CPUs or PLC units with no onboard high-speed I/O can also be used for motion control applications simply by adding one or more of the HSIO high-speed expansion modules.

• BX-HSIO1 - 250kHz high-speed input/output module (sinking single-ended output(s))
• BX-HSIO2 - 250kHz high-speed input/output module (sourcing single-ended output(s))
• BX-HSIO4 - 2MHz high-speed input/output module (sinking/sourcing /TTL, diferential and single-ended output(s))

All BRX PLC models, using built-in or expansion high-speed I/O, can be used to track rapid encoder pulses, drive stepper motors, or can be configured for other counter/timer, axis/pulse, pulse-width-modulated or table-driven functions:

• Timer/Counter: BRX PLCs can be configured to count input pulses, or measure the time between pulses, up to a 2MHz maximum pulse rate.
• Axis/Pulse: BRX PLCs can control up to 27 independent axes of motion or 7 groups of coordinated motion with additional virtual axes for internal control and following applications.
• Pulse Width Modulation (PWM): The high-speed outputs can also be used to generate a carrier frequency with varying pulse widths.
• Table-driven: Tables of preset values can be used to turn the high-speed outputs ON and OFF based on the pulse count values of one high-speed input.

Do-more Designer software includes many easily configured function blocks for several common motion profiles. Choose the one you need and fill in the blanks for your particular application. If you need a custom profile, the AXSCRIPT instruction allows you to create your own sequence of axis commands.
