PHD-11TD-21

Overview

Isolated safety barrier keng detection side: PHD-11TD-21, analog input ampo output, metung a input ampo metung a output.

^ Ing makabukud a barrier malyari yang mag-isolate at mag-transmit king 4~20mA signal o DC 4 ~ 20 mA signal a gewa ning transmitter king delikadung lugal papunta king ligtas a lugal. Nung ing transmitter adwa ya o atlung kawad a sistema, ing safety barrier mamye yang kuryenti para keng transmitter.

^ Ing produktung ini mangailangan yang panlual a 20-35VDC a suplay ning kuryenti.

^ Ing produktu ayni suportan ne ing HART signal ampo ing disconnection alarm.

* Tandanan: nung kailangan me ing aliwang parameters na niting produktu, pakisabi me ing kekaming technical support. nung ing output aliwang parameters ya, mipalabas ya keng bilang 9, ampo ing specific a parameters mipalabas ya kaybat ning model number.

Overview

Ing analog input isolated safety barrier mamye yang isolated powersuplay para kareng adwang - ampo atlung wire transmitters kareng delikadung lugal.

Ing 4~20mA signal a gewa ning transmitter o current source mipadala ya ibat keng hazardous area papunta keng safe area output, inya sa’t mag drive ya ing load keng safe area. Para kareng adwa - o atlung wire transmitters o current source signals, ining safety barrier susuportan ne ing bidirectional a komunikasyun ning Hart digital signal a maka-superimpose keng 4~20mA signal ampo atin yang wire breakage alarm function.

Ing produktung ini mangailangan yang independenting power supply, a maki makabukud a powersupply, input, ampo output terminals.
