Common faults of signal isolators include the following:
1. Unstable signal transmission: the output signal is intermittent, fluctuates greatly, or is inconsistent with the input signal. This may be caused by circuit
aging, poor contact, interference, etc. 2. No output signal: The input signal is normal, but the isolator has no output signal. It may be that the internal circuit is damaged, the power supply fails, or the component fails.
3. Accuracy deviation: There is a large deviation between the accuracy of the output signal and the nominal accuracy, which may be due to temperature drift, performance degradation caused by long-term use, etc.
4. Power supply problems: The power indicator light does not light up, the power supply voltage is unstable or the power supply is short-circuited, etc., which affects the normal operation of the isolator.
5. Decreased anti-interference ability: external interference cannot be effectively suppressed, causing the output signal to be affected by noise.
6. Shell damage: It may affect the protective performance and electrical insulation performance of the isolator.

Power failure: Power problems with the signal isolator may cause it to not function properly. A power failure may be due to a problem with the power supply itself or it may be caused by a faulty power line.
Signal input failure: The signal input port of the signal isolator may malfunction, resulting in the inability to receive signals correctly. This may be caused by a faulty connection line, damaged input interface, etc.
Signal output failure: The signal output port of the signal isolator may malfunction, resulting in the failure to output the signal correctly. This may be caused by connection line failure, damage to the output interface, etc.
Common faults of signal isolator
Fault Indicator Issues: Signal isolators are often equipped with a fault indicator light, but if there is a problem with this light, it may result in the failure of the device to be properly diagnosed.
2. Signal interference problem: The signal isolator is sometimes interfered by external signals, causing problems with the output signal. This may be caused by electromagnetic interference, ground interference, etc.
Circuit board failure: The circuit board of the signal isolator itself may also fail, such as damaged capacitors failed resistors , etc.
The above are the common faults of signal isolators that we often encounter.
