UNI900A2 Loss In Weigh Feeder Controller Batching system with 32 bit high speed MCU
CE, EMC ApprovalUNI900A2 is specifically designed for loss-in-weight applications. Once UNI900A2 starts the operation, the flow rate is calculated by measuring the decrease in material weight from the weighing hopper, and compared to the time it takes for this decrease.
Features
◆ 32-bit high-speed MCU, which can accurately track
target flow with really small dead zone and realize
high-accuracy flow control
◆ Advanced model control algorithm can accurately
predict the effect of every control value, so as to
adjust the control value in advance with fast response
and small overshoot
◆ Multi belt scales can compose a master-slave batching
system through CAN interface
◆ Adopts incremental control method without fluctuation
when auto/manual switches
◆ Auto non-linear adjustment
◆ Standardizes weighing signal into mill volt
◆ With volumetric measurement mode
◆ All function can be customized
◆ Complete aluminum shell mold, strong and durable
◆ 8-ch isolation switch inputs, 8-ch relay outputs
◆ RS232/485 interface, CAN interface (optional),
DP interface (optional) and CC-Link (optional)
◆ 1-ch 4~20mA signal input, 2-ch 4~20mA outputs
(the 3rd ch output of 4-20mA optional)
