LED Mini Crane Weigh Feeder Controller , Truck Scale Indicator RS232/RS485 Communication

Main Features:

• Suitable for Crane [Wheel Crane, Travelling Crane, Frame Crane, Bridge Crane and so on] Overload Protection. When the lifting weight exceeds the set values, the controller will output the signal of Sound-light Pre-alarm for Weight High Limit, Delay-stop for Weight Higher Limit and Emergency-stop for Weight Highest Limit to protect the crane.
• EMC design with high anti-jamming capability, suitable for industrial environment.
• 32-bit ARM CPU with 48MHz clock & high arithmetic speed.
• 5 Red LED digital tubes for English character and digit display.
• Menu&Shortcut mode operation.
• 24-bit High-precision and high-speed ∑-△A/D conversion module with 1/1,000,000 internal resolution and sampling frequency 640Hz.
• Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strong vibration on the load receptor, and the rapid response capability when the weight signal changes.
• Optional weighing input signal mV, V and mA for connecting ‘【mV】Output Type Loadcell’, ‘【V】Voltage Output Type Weighing Transmitter’ and ‘【mA】Current Output Type Weighing Transmitter’.
• Zero Upon Power Up, Zero Auto-tracking, Manual/Auto Zero and Zero Calibration available.
• Load Calibration and Data Calibration available.
• Auto-locking, Key-locking, Key-unlocking, Digital Setting&Calibration and I/O Testing functions available.
• 1 Normally open switch input [DI]and 2 Relay switches with normally open and normally closed contacts for outputting alarm signals.
• 1 Definable analog signal output [AO: 4~20mA / 0~20mA / 0~5V / 0~10V / …].
• RS232 and RS485 communication ports for connecting Host IPC/PLC and LED Remote Display.
• With the multitasking mode, the processes of weighing, alarm output and signal transmission will not be interrupted by parameter setting and the other operations.
