Machine Protection Systems

Most machinery protection systems on the market require the user to identify a range of modules to fulfil a fairly standard machine protection requirement.

Typical plug in modules are required to configure the system, add alarm relay interfaces, include analogue outputs for the DCS, provide a communication interface, etc…….. but not with Sentry G3.

The best way to consider the Sentry G3 concept is to look at all the features that are available in a typical machine protection rack fitted with all the various plug on card options……. Sentry G3 compresses all these functions into a single module.

1. No communication card is required……. the module has direct dual redundant modbus connections.
2. No alarm relay card is required……. the module has built in alarm relays with programmable logic.
3. No analogue output card is required…….the module offers two analogue outputs per channel, each can be configured for either current or voltage.
4. No rear of rack transducer interface cards required…… program the Sentry G3 module exactly to the sensor interface requirements.
5. No additional display module is required…… Sentry G3 has its own inbuilt intuitive display.
