PHD-22HD-2121
Tirohanga
He arai haumaru wehe i te taha rapu: PHD-22HD-2121, te whakaurunga me te putanga tairitenga, te whakauru rua me te putanga rua.
Ka taea e te arai taratahi te wehe me te tuku i te tohu 4~20mA ranei te tohu DC 4~20 mA i hangaia e te kaiwhakawhiti i te waahi kino ki te waahi haumaru. I te wa e rua-waea, toru-waea ranei te kaiwhakawhiti pūnaha, te arai haumaru whakarato mana mo te tuku.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake.
Ka tautoko tenei hua i te tohu HART me te whakaoho momotu.
