The M200 DC transducer trips have endless applications. As the name implies they are designed to accept inputs from transducers and transmitters, and provide a relay operation when the transducer signal deviates outside a pre-set limit Any of the M100 series transducers can be used with the transducer trip. A typical application is to control power using a M100-WA5 with a 4-20mA signal fed to a M200- TAO. For example the output goes above a pre-set limit of 80%, the TAO relay will close, setting off an alarm or shutting down a process Either DC voltage or DC current inputs can be used. As is common with all the M200 relays, on over units the relay energizes when the input signal exceeds the trip point and on under units the relay de-energizes when the input signal goes below the trip point A red LED indicates the state of the relay, whilst a green LED indicates the condition of the power supply.
