SBC 2000 Family of Controllers

SBC-2000 Family of Weigh Feeder Controllers… for Acrison “Weight-Loss” Weigh Feeders


Acrison’s compact, state-of-the-art SBC-2000 Family of Weigh Feeder Controllers has been designed with an emphasis on performance, small size, reliability and ease of use.  In operation, they provide robust, highly accurate control of Acrison’s internationally respected dry solids and liquid “Weight-Loss” Weigh Feeders.  SBC-2000 Controllers include virtually all of the features and functions previously available in Acrison’s MD-II-2000 and C/BC-702 Controllers, while adding many new features as well.

Available in three distinct models, SBC-2000 Controllers have identical weigh feeder control capabilities:

SBC-2000 CM – controls a single Acrison Weigh Feeder in conjunction with a separate variable speed motor controller. It is designed primarily for applications that use a central computer, PLC or DCS for monitoring and control, and do not require a local operator interface.  (An optional local keyboard display unit is available.)

SBC-2000 DSP and SBC-2000 DSP/C – For applications that require a local operator interface, the Model SBC-2000 DSP integrates a Model SBC-2000 CM Controller with a monochrome LCD graphics display and a Lexan membrane keypad. The Model SBC-2000 DSP/C Controller includes a metallic console designed with a TFT color graphics display and piezo electric keypad.

SBC-2000 MFC – consists of one or more (20 maximum) SBC-2000 CM or DSP Controllers plus an 15”, 17" or 18" Color Touchscreen for total remote monitoring and control of multiple weigh feeders that may not have central computer control.

Minimized Hardware Design – provides high reliability and economy of space (one 19” card rack can hold up to 20 weigh feeder control modules)
Minimal Controller to Feeder Connection Points – results in fewer connectors with better long-term reliability (a mother board is not used)
“Hot Swap” Design/Front Accessible Modules – permits easier maintenance by allowing SBC-2000 CM Modules to be replaced without turning power off
Low Power CMOS Logic with Over-Spec Power Supplies – provides cool running electronics for longer product life (redundant power supply available for extra high reliability)
Electrically Isolated Serial and Digital I/O – are standard on all controller models
UL, CSA and IEC (CE) Certifications – apply to all controller models
Native Ethernet / IP and Modbus TCP
