SAI140 e fana ka lintlha tse 4 tsa papiso tse khethang ho tloha ho 4 ~ 20 mA le 0 ~ 10V ka litlhophiso tsa jumper ea onboard. Ke sample reiti makhetlo a 5/motsotsoana (litlhahiso tse 4).
E 'ngoe ea RS485 Serial Port (Terminal Block interface) e tšehetsa protocol ea Modbus RTU.
Lintlha:
Mofuta oa mantsoe : Integer e sa ngolisoang
Qeto: likotoana tse 16
Taelo ea mantsoe : High byte ka pele, Mofuta o tlase ka morao.
Boleng bo nepahetseng ho tsoa ho kenyelletso ea analog e lokela ho ba boleng bo fumanoeng bo arotsoe ke 1000.
