Available in 55mm x 112mm or 100 x 112mm DIN rail casesApplicationFor over protection, under protection and combined under & over protection available in AC current AC voltage & frequency versions. Millivolt trip, DC voltage trip, Reverse Power, Phase sequence & Phase balance relays also available in our extensive range of protection relays..Selection GuideM200-TAUD.C. volts or mA under tripM200-TAOD.C. volts or mA over tripM200-TACD.C. volts or mA combined tripTypical ApplicationsThe M200 DC transducer trips have endless applications, as the name implies they are designed to take inputs from transducers and transmitters, providing a relay operation, when the transducer signal deviates outside the preset limit. Any of the M100 series transducers can be used with the transducer trip.A typical application is to control power using a M100-WA with 4-20mA signal fed to a M200-TAO. For example the output goes with a preset limit of 80%, the TAO relay will close, setting off an alarm or shutting down a process. Either D.C. voltage or D.C. current inputs can be used. As is common with all the M200 relays, on over units the relay energises when the input exceeds the trip point. 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 condition of the power supply.Technical SpecificationsINPUTRated value In0<20mA or 4-20mAVoltage1 voltRated value Un1 < 50 volt or 1.5 voltImpedance10k Ohm / voltOverload2 x In 1.5 x Un continuous10 x In 2 x Un for 3 secondsSETPOINTRange overAdjustable 40% to 120% for both voltage or current input.Range UnderAdjustable 0 to 80% for both voltage or current inputRepeatabilityBetter than 0.5% of full spanTime delayAdjustable 200mS to 10 secondsDifferentialFixed 5%AUXILIARYA.C.
