Universal weight controller is a weight controller for industrial control field. It integrates weight display, analog signal output, Modbus-RTU communication, large screen communication, switching input and relay output. High-speed 24-bit A/D converter and 16-bit D/A converter are adopted. All interfaces are processed by photoelectric isolation. Fully consider the complexity of electromagnetic interference on the industrial site, and carefully design the software and hardware, which is suitable for the application of industrial sites in building materials, chemical industry, grain, metallurgy and other industries.

1.2 The main feature points

◆Built-in anti- EMC interference circuit, strong anti-electromagnetic interference ability, stable data, suitable for industrial field applications.

◆ Three calibration methods: weight calibration, calibration parameter modification, sensitivity input calibration (weightless calibration).

◆  Can choose RS232 or RS485 two ways, support Modbus-RTU communication multi-word continuous reading and writing function.

◆ You  can set the analog output type: 0 to 20mA , 4 to 20mA , 0 to 5V, or 0 to 10V .

◆  Relay output mode can be set : sorting, fixed value, quantitative, decrement, batching, peak and other modes.

◆  Supports jog feeding when the actual feeding weight is out of tolerance.

◆  Support the host computer to calibrate the controller.

◆ The  number of cycle ingredients can be set to support the function of infinite cycle ingredients.

◆  Accumulation of batching times and reading function of the actual batching weight on the host computer.

◆  Supports a series of operations such as communication zero setting, peeling, starting and stopping of ingredients.

◆  Stainless steel anti-corrosion panel and full metal shielded shell.

◆  24BIT S - △ type A / D conversion, the maximum A / D pulses: 1,000,000 .

◆ AD rate: 15 times / second, 30 times / second, 60 times / second, 100 times / second, 200 times / second.

◆  Three calibration methods: weight calibration, calibration parameter modification, sensitivity input calibration (weightless calibration).

◆  . 7 bit 0.56 inch LED digital display , 10 segments beam indicated . 7 th LED indicators.

1.3 Technical parameters

◆  excitation voltage: 5.0VDC , can be driven . 8 only 350 W is an analog sensor.

◆  Range signal range: 1.5 ~ 40mV .

◆  Zero signal range: -40 to 38.5mV .

◆  Analog current output: Max 500 Ω.

◆  Analog voltage output: Min 10 K Ω.

◆  Relay contact capacity: AC3A/ 250V , DC3A/ 30V .

◆ The  highest sensitivity: 0.3uV / d .

◆  Non-linear: better than 0.01% FS .

◆  Supply Voltage Range: AC 200 is ~ 242V , frequency 49 ~ 51Hz , maximum power consumption 8 watts. The     controller needs a good ground wire, and should not share a power source with equipment that easily generates   power noise, such as motors, relays, or heaters.

◆  Operating temperature: -20 ℃ ～50 ℃, Humidity is 10 % to 95 %, non-condensing.

◆  Storage temperature: -30 ℃ ～60 ℃, Humidity is 10 % to 95 %, non-condensing.
