SY017: Recipe Batch Controller

 The SY017 is designed to provide a complete monitor and control solution for multi-recipe batching systems, with non-volatile memory storing up to 100 recipes. Weight measurement is achieved with an 18bit ADC, and the built-in excitation supply will drive up to four 350Ω load cells. An optional flow meter input is also available. The unit controls the switching of up to 17 valves, motors, pumps or contactors etc. using relays rated at 5A 250V AC or 5A at 30V DC. A 4-20mA output is available as an option for remote indicators or a variety process control applications. speedcontrol of mixers conveyors etc.

Batch and recipe entry is simple, either via the keypad or the optional serial interface. Each material can be controlled by weight, metered flow or by time.  Hand adding of ingredients is also supported, and any combination of these settings can be programmed to suit the user’s needs. 

In bulk bag handling systems the controller can warn of insufficient material to complete a recipe and allow the user to continue until bag runs out, pause while the bag is replaced, and resume at the operator’s prompt. 

A ‘ratio’ mode is available which allows an ingredient to be dispensed via the flow channel in the precise quantity required dependent on the measured weight of another ingredient.

Calibration figures are stored in non-volatile memory, protected by a PIN number and optionally a key-lock. Any change to the calibration increments a non-resettable counter. The SY017 meets the requirements of QSRMC.

The optional RS232 comms module allows direct printing of time-stamped batch tickets to standard serial printers. Full remote control of the SY017 is also possible via this interface, and with the SY012 data logger module fitted up to 4000 batch summaries can be retrieved.

For more complex systems the RS485 network comms module is available. The SY017 can be configured as either a master or slave device. SY019 units can be used as part of this network to expand the number of inputs/outputs, and custom software is available which allows graphical control of the whole system via a PC. The stand-alone functions of the SY017 then provide redundancy allowing batching to continue even if the PC’s operation is interrupted. This provides a safety advantage over a traditional PLC-based system; a 'belts and braces' approach as our customers up here in the North say!

The SY017 is also available ready-mounted into a panel along with a panel-mount ticket printer and vandal-proof die-cast keypad (see the SD007 pictured above).
