PH D-22T F-2727
Overview
Isolated safety barrier keng detection side: PHD-22TF-2727, digital input ampo output, dual input ampo dual output.
Ing makabukud a barrier malyari neng i-convert ing proximity switch ampo ing contact input keng delikadung lugal keng relay contact signal ampo i-transmit ne keng ligtas a lugal.
Ing output relay atin yang selection switch ning "ON/OFF" a sitwasyun. Dagdag pa, atin yang input signal short-circuit o open-circuit alarm indication, ing circuit mamye yang kuryenti para keng input sensor.
Ing produktung ini mangailangan yang panlual a 20-35VDC a suplay ning kuryenti.
Ing signal status indicator maka set ya keng red ampo yellow a sulu para ipabalu ing working status ning output relay, nung para ya keng alarming kanita ing sulu mapula ya, kabang normal yang operasyun ing sulu yellow ya.
* Bus power supply, lawan me ing appendix para kareng detalye.
