Can an opto-isolated input be analog?
The opto-isolated inputs are digital. To answer the larger question, optocouplers can be analog in the current domain; The “DC current transfer ratio” (CTR DC) describes the current gain/attenuation provided by the coupler. You need more answers to believe, ok.
Can an opto isolator be used with a PIC 12f683 output ( PIN5 )?
Can an opto isolator be used with a pic 12F683 output (pin5 ! The voltage at the pin is > < 2.5v. I want it to switch ON a 2n3904 transistor. Adopting to finite voltages like .2v and 1.6v will depend on the datasheet of your specific optocoupler and other external components you use to manipulate those values.
Can a optocoupler be used as an output device?
When I supplied power to the LED side of the optocoupler (pins 1, 2, 3), I would see the dimly lit LED turn OFF. The LED would turn back on again when I removed power from the LED side of the optocoupler. Optocouplers can be used as either input or output devices.
Which is the output pin on the 7447 decoder?
In the 7447 BCD to 7-segment decoder chip, pin 4 is BI’/RBO’. That pin acts both as input and output. I would like to understand how exactly the internal circuitry works to make this possible.
How many channels are there in the opto isolated module?
The module consists of 16 nos. of Opto isolated input channels, which are wired to the field inputs (Potential Free Contacts). The 16 Channels are divided into 2 groups of 8 Channels each.
How is the DCS output isolated from the PLC?
The inputs are isolated using Opto-coupler & 24 VDC Output is generated for the PLC/DCS Inputs when corresponding field contact is closed. The Channel status is indicted with green LED, which switches ON when corresponding input contacts is closed.
How does the can fim-16 digital input module work?
CAN – FIM – 16 provide ISOLATION between Digital Field inputs & PLC/DCS Modules. The module consists of 16 nos. of Opto isolated input channels, which are wired to the field inputs (Potential Free Contacts). The 16 Channels are divided into 2 groups of 8 Channels each.
