Branch Expansion PLCVelocio's Branch Expansion PLC The Branch Expansion PLC is a member of the Velocio's groundbreaking series of programmable logic controllers. These PLCs introduce revolutionary new concepts, capabilities, performance and ease of use features to the automation market. They constitute a generational leap over the staid products that have comprised the PLC world for years. A key feature of the Velocio PLC line is distributed operation. By placing IO and optionally, program intelligence, right at every point of application, historical problems with accuracy, reliability, safety, installation cost, maintenance and others, are radically reduced or eliminated. Branch Expansion PLCs expand the tree for a distributed system. Each Expansion unit contains up to 30 points of IO and can contain its own program. vLink communications ports on the Branch Expansion communicate autonomously, upstream to the Branch or Expansion unit above it in the tree, and downstream to the next level of Branch Expansion PLCs. Three levels - Interactive, graphical full system debug functionality - Software reusablity of Branch Expansions are permissible in a system. application, each Branch Expansion PLC, that is configured as IO, is expansion IO for the next level PLC above it that has a program. If the application places a program in a Branch Expansion, Branch Expansion units that are below it in the tree and configured as IO serve as its expansion IO. Branch Expansion PLCs are programmable, using Velocio's vBuilder software. They connect to a PC through vLink communications and any Branch and Branch Expansion PLCs above them in the tree. Through a single USB communication link to a PC an entire system of Velocio PLCs can be programmed, debugged and deployed. Branch Expansion PLCs feature integrated local IO. Up to 12 digital inputs, 12 digital outputs and 6 analog inputs are available. In addition to basic input/output capabilities, the Branch Expansion can be configured for high speed digital pulse counting for either simple pulse or quadrature inputs. It can also be configured for high speed stepper motion pulse and direction control. This PLC, which fits in a shirt pocket, is a building block of the most advanced, flexible, easiest to develop and deploy automation technology available anywhere. • Machine control • Process control • Entire manufacturing line control • Building automation • Distributed system control • Motion system control • Machine to Machine applications - 6 Analog Inputs Distributed IO Expansion Distributed Processing Platform • vLink Communications with host • Two vLink Expansion Communications ports • vLink communications up to 100 meters (328 feet) • Smallest physical footprint of any PLC • Software features at or beyond those of the most advanced PLCs and Programmable Automation Controllers (PACs) • Program development via vBuilder - Graphical program development - Flow Chart Programming - Ladder Logic Programming - Distributed Processing - Integrated deployment and debug of distributed processing systems Exp 11 : 6 digital in, 6 digital out, 2 vLink ports Exp 22 : 12 digital in, 12 digital out, 2 vLink ports Exp 221v5 : 12 DI, 12 DO, 6 Analog in (0-5V), 2 vLink Exp 221v10 : 12 DI, 12 DO, 6 Analog in (0-10V), 2 vLink Exp 221c : 12 DI, 12 DO, 6 Analog in (0-20mA), 2 vLink Automatic communications between system modules Greatly enhanced and efficient development process Reduced systems cost Reduced development time Improved reliability Automatic machine to machine operations Total system deployment and debug

vBuilder Software Like all Velocio PLCs, Branch Expansion can be custom programmed for your application's requirements, using Velocio Builder (vBuilder). vBuilder is an application that is distributed free of charge, for use in developing programs for Velocio PLCs. vBuilder is the most powerful, flexible, intuitive, easy to use graphical program development software available in the industry. That includes the packages from the industry titans, that will cost you hundreds to thousands of dollars. We're sure that you'll love it. In vBuilder, you can develop applications using either Flow Chart,...

Branch Expansion Inputs and Outputs Each Branch Expansion PLC can directly connect to 6 or 12 digital inputs, 6 or 12 digital outputs and 0 or 6 analog inputs. There are up to 5 IO ports. Each IO port has an 8 pin pluggable terminal block connector. Each of these port connectors connect to 6 points of IO. digital analog signal direction The layout of Branch Expansion IO ports (looking from the top of the Branch Expansion), is shown here. Digital Inputs : Any connection to DC voltage between 3 and 30 VDC is sensed as a ‘1’. Any connection to ground (or voltage below 0.8VDC) or an open connection...

0 Analog Inputs : Branch Expansion PLCs are available with 6 analog inputs (1 port). Expansion analog input interfaces are available for either 0-5VDC, 0-10VDC or 0-20mA. Analog inputs are normally used to connect to transducer outputs. Such transducers measure some physical parameter, such as pressure, temperature, liquid level, position, pH level, or other such continuously variable measurement. The signal output should be connected to a signal input on the Branch Expansion analog port and the transducer return or ground reference line must be connected to the PLC ground pin, next to signal...

Wire Connections to the PLC Pluggable Terminal Blocks Branch Expansion units come with pluggable terminal blocks, like the one shown on the on the right. Connect your wires using the larger circular holes on the top row of the orientation shown. Looking at the connector, in the orientation shown from left to right, the eight wire positions are ground, six signal positions 1 through 6, and either a no connect (analog), VDC (output) or 5VDC from the 5V power input to the PLC (input). If you have solid wire, you simply need to strip the insulation back about 1/8 inch, insert each wire into the proper...
