Used for wind turbine condition monitoring, hydraulic system tracking, and environmental data acquisition, enabling consolidation of multiple sensors into a single backplane slot for compact cabinet designs.
Does it support 2-wire and 4-wire sensors?
Yes. 2-wire sensors typically require an external 24V loop supply; the module measures the signals with high precision.
Can voltage and current signals be mixed?
Yes. Each channel can be individually configured via Bachmann SolutionCenter, allowing simultaneous monitoring of different signal types on one module.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
