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 energises
when the input signal exceeds the trip point and on under units the relay
de-energises 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.
The voltage relays monitor their own power supply so auxiliary power is not necessary. A green LED indicates a supply is present. The relays feature an adjustable power supply, allowing flexible selection of the connected nominal voltage.
