Note: analog interface is composed of precision electronic components, wiring errors or continuous overload input,
which will cause permanent damage to device.
The input signals in this analog transmission channel through the optical fiber transmission, will be reductive out in the channel
corresponded to the analog output interface.
1)
Each channel for the analog inputs can select three signal modes, including (4-20) mA, (0-5) VDC, and (0-10) VDC input. Ai
- is the reference earth wire for each input signal, while Ai + is the positive signal wire for each input signal.
2)
Each channel for the analog outputs can also choose corresponding three signal mode, including (4-20) mA(Please choose
four-wire input method when connecting to PLC) ,(0-5)VDC and (0-10)VDC output. Ai - is the reference earth wire for each
output signal, while Ai + is the positive signal wire for each output signal.
Note:
output current at the receiving end A- can not be “0”, current load and receiving end need to be powered
independently when necessary and add current signal isolator between the two devices.
3)
The (4-20)mA analog fiber optic converter support four-wire system standard, please note the wire connection method while
connecting with two-wire system transducer, no support connect power to fiber optic converter terminal Ai+, Ai-, or will
damage the machine. Please refer below two-wire and four-wire transmitter wiring.
