The M200 DC voltage trips are commonly used for monitoring battery voltage conditions but can be used in any application where the DC voltage level is critical. The user is provided with an adjustable set-point of 0-80% on under units and 40-120% on over units. The differential is internally set at 5%; no time delay is provided. As is common with all 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 state of the power supply.
