Power Supply Unit
Designed for Integration for Power Supply in Hazardous Areas WM-Ex
For use in automated processes in hazardous environments (Zone 1; Class I, Div. 1).
WMH-Ex
For use in automated processes in hazardous environments (Zone 1, 21; Class I, II, III, Div. 1) – connectable without terminal.
Modular
Free places for additional slot cards to connect an additional interface at ACM200.
Industrial Housing
Is constructed of stainless steel and certified IP66. The housing will withstand harsh environments, and includes integrated mounting brackets to simplify installation.
APS768x & ACM200 New solution for connecting WM-Ex & WMH-Ex in the hazardous area Customer benefits • Transmission distance between the weighing sensor and the data processor (PLC) has increased from 100 m to 400 m which ensures enhanced safety for the application. • The modular design allows being flexible and expandable not only to power the application terminal and the weighing platforms which have intrinsically safe outputs, but also to exchange data.
