Batch weight controller stores 99
recipes
An extremely intelligent batch weight controller, which can store up to 99 recipes with up to 16 separate ingredients, is designed to read load cell signals making it a very accurate system.
The SY017 Multi-Recipe Batch Weight Controller from Synectic Design is an extremely intelligent batch weight controller, which can store up to 99 recipes with up to 16 separate ingredients As with all Synectic Design products, the SY017 is sophisticated yet simple to operate

Solenoids added to process control electronics
Synectic Design has announced a new link with a specialist UK solenoid valve manufacturer.
The SY017 uses an 18 bit ADC, Specifically designed to read load cell signals making it much more accurate than standard PLC ADC systems which are generally successive approximation types with poor noise rejection; the unit has a response of 16Hz.
The controller can accept inputs coming from either load cells or flow meters (or both); a remote stop/start button can also be connected.
The unit has a total of 17 output (6A/270V) relays - 16 can be used for ingredient control and the 17th can be used to discharge a hopper or start a mixer etc after a preset amount of time.

Ease of use for digital bridge amplifier
The SY034 digital bridge amplifier is the ideal tool for numerous measurement applications where ease of use and accuracy are important.
An example of this timing feature is for chemical processes were for example a wait or mixing is required, or steam added etc for a set period of time.
Each ingredient is controlled by a relay, with automatic in-flight compensation.
The operation of each relay in indicated via LEDs on the front panel.
The controller's memory can store up to 99 recipes, with a name for each ingredient.
Each relay can control the feed of an ingredient, or the relays can be operated in pairs switching on a pump and valve for up to 8 ingredients.
Companies currently using the SY017 include: Kingspan Group - they are the largest building components manufacturer in the world, SY017's are currently being used for chemical blending to produce polymer building systems.
Kingspan have had uninterrupted production since 1996 utilising their Synectic Batch Blending Systems; the units are used to dispense some chemicals in extremely small quantities, demonstrating the SY017's precision control abilities.
Another company that uses SY017s is Centura Foods (in Middlewich), they are makers of Bisto, Paxo and most supermarket own-brand stock cubes.
The SY017's at Centura Foods use the unit's self-computing batching facility, where it runs without the need for any manual input during a batching run (it doesn't even need to be told when hoppers have been refilled, or how much has been added).
The unit can also allow for a situation where one or more of the components of the mix run out (mid-batch), therefore eliminating any material wastage.
In a two ingredient recipe it can compute the ratio and complete a mix.
The unit uses a full numeric keypad for data entry or if an RS232 link is fitted, it can be remotely controlled from a computer.
With RS232 it can be programmed from a PC or personal organiser As the SY017 has a manual control front panel, the unit can be controlled, even if the remote computer is not operational.
The controller can also be built into a network via an RS485 connection.
Further expansion is available by connecting the unit to an SY019 multi I/O unit.
Options available with the SY017 include: a reduced system measuring flow only, or a full system offering the measurement of flow and weight; an RS232 serial interface for connection to PC, personal organiser or printer; an RS485 interface for networking capabilities and an internal data logger.
Synectic Design Ltd has been designing and manufacturing industrial process control and measurement instrumentation and systems since 1993 and are considered as leaders in the process electronics industry.
