Dear all, Could anyone know about permitted transfer distance for current signal 4-20mA of Transmitter? I am using pressure transmitter SITRANS P220, the distance from transmitter to PLC module is about 450m, is it possible to connect current signal of transmitter directly to PLC module? In case of using repeater, which one should be chosen and how many repeater needed? Please refer attachment for P220 specification. AttachmentP220.pdf (1151 Downloads) |
