PHD-12TF-288
Overview
Isolated safety barrier keng detection side: PHD-12TF-288, digital input ampo output, metung a input ampo dual output.
^ Ing makabukud a barrier malyari neng i-convert ing proximity switch ampo ing contact input keng delikadung lugal keng transistor output signal ampo i-transmit ne keng ligtas a lugal. Ing output transistor pilatan ning ec atin yang selection switch ning "inverted phase/normal phase" , dagdag pa, atin yang input signal short circuit o open circuit alarm indicator, ing circuit mamye yang input sensor power supply.
^ 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 maputi ya, kabang normal yang operasyun ing sulu yellow ya.
* Bus power supply, lawan me ing appendix para kareng detalye.
