evaluation device WWA-1
The compact WWA-1 evaluation device is the versatile all-rounder for your scale! Equipped with an ultra-bright LED matrix display (easily readable even in poor visibility conditions), it offers either a precise weight display or optimal system integration thanks to numerous optional interfaces such as RS232, USB, Modbus RTU or radio. Perfect for industrial applications, logistics, or use in your weighing systems.
Highlights:
- Robust design: protection class IP66/IP68, dimensions 191 x 68 x 60 mm.
- Flexible display: 48x16 pixels, individually adjustable brightness in 10 levels, one or two lines.
- Versatile interfaces: From analog output to various bus systems – ideal for any system architecture.
- Measuring precision: Direct connection of up to 4 load cells or 16 via connection box.
- Power options: Operation with 230VAC, 12–24VDC or long-lasting LiFePo4 battery.
With innovative functions such as automatic zeroing, an animal weighing program, dosing programs and optional extensions such as LAN/WLAN, radio transmission, the WWA-1 impresses as a flexible and powerful evaluation device for the highest demands.
