A static grounding verification system for industrial applications requiring multi-point grounding monitoring, designed to check multiple grounding lines simultaneously, confirm true grounding and improve site safety control in complex operations.
Earthing Pro MUL is designed for industrial applications where multiple grounding lines need to be monitored at the same time.
Earthing Pro MUL is a configurable multi-channel grounding monitor with four independent channels as standard and expansion to 16 channels.
Larger systems can be engineered with the factory.
It is intended for multi-bay loading, railcar terminals, multi-container filling, powder-processing equipment, fluid-bed systems and installations containing several conductive components that must be supervised from one system.
In complex loading and transfer operations, more than one grounding point often needs to be monitored.
When multiple pieces of equipment, loading bays or grounding loops must be confirmed at the same time, standard single-channel or dual-channel systems may not be sufficient.
Earthing Pro MUL monitors multiple grounding lines simultaneously, helping confirm that all required grounding conditions are safe before operation begins and improving both safety and site management efficiency.
Connect each field clamp to its assigned conductive object or grounding point.
The intrinsically safe detection module in each junction box independently monitors its loop to ≤10 Ω.
Every channel provides independent red/green status and drives its dedicated relay output.
Selected channels can be combined into a customer-defined common-permissive condition.
Channel values and fault states are transmitted to the centralized LCD in the safe area.
Common fault, communication fault, broken-wire and watchdog monitoring support the configured non-permissive response.

It is used for industrial loading and transfer operations where multiple grounding lines need to be monitored at the same time.
Earthing Pro MUL supports more channels and is better suited for more complex sites with more grounding points to monitor.
Yes. Earthing Pro MUL is suitable for different channel configurations based on site requirements.
Yes. Earthing Pro MUL can provide interlock output for integration with pumps, valves or control systems.
Four channels are standard and up to 16 are supported. Larger systems and the required relay/group logic can be engineered with the factory.
The LCD overview presents configured devices and clamps, operating mode, live resistance, green Normal status, red Grounding Alarm or NO TRUCK status, and summary counters for connected devices and active alarms. The display is installed in a control room or another safe area.
Yes. Each channel has an independent measurement, status and relay output. Selected channels can also be combined into a common-permissive condition.
The system supports common-fault, communication-fault, broken-wire and watchdog monitoring for the configured safety response.
