Switch input relay chuahnak he aa thenmi himnak khamnak, cu nih cun ttihnung hmun ah switch pehtlaihnak asiloah naih tein a ummi switch hna in himnak khamnak chungin chuahnak relay he himnak hmun ah a thleidan i a kuat. Line palhnak hmuh khawhnak cu module cunglei ah LED hmangin tuah khawh a si. Module i dial switch cu in-phase asiloah hnulei uknak luhternak le chuahnak chiahnak caah hman a si, cun line palhnak hmuh khawhnak ralrin peknak riantuannak kha on le phih khawhnak caah hman a si.
Hi thilri nih hin a dang tein mei a herh, a dang tein mei a herh, luhternak le chuahnak terminal hna he.

Bialehnak: 1. PHD-12TF-277 nih luhternak tthen 2 aa tel lo
2. Power rail i power supply cu thim khawhmi riantuannak a si.
Hmantu hna nih order an tuah tikah power supply mode kha an langhter a hau.
Cahmai 89 i aa pehtlaimi kha zoh.
Line palhnak hmuh khawhnak (LFD)
Hmantu hna nih module cunglei ah "ON" lei kha an thim khawh palhnak hmuh khawhnak riantuannak kha tuah khawh awk le ralrinnak langhter awkah LED ceunak sen. Hmun ah luhternak current>7mA, short circuit alarm (SC);
Hmun ah luhternak current pehtlaihnak luhternak nih palhnak hmuh khawhnak rian a herh (hri a kiak, a tawi circuit), 22k Ω resistor cu a donghnak pahnih ah aa tluk tein pehtlaih a si lai switch, le 680 Ω resistor cu a hnu hnu in pehtlaih a si lai (as switch pehtlaihnak II caah hri suaimi ah langhter a si).
