Optoisolators - Logic Output

PS9121-F3-AX application field and working principle

The PS9121-F3-AX is a logic output optoisolator in the increasingly popular PS9121 range. This range utilizes filter-free solutions, capable of driving an LED at up to 300 VDC and 25 mA, allowing for a combination of high power and small size. This optoisolator has been designed for use in business, industrial, home automation and telecommunication applications.

The PS9121-F3-AX works with an AC or DC signaling system and includes built in protection features to help prevent arcing in the output LED. This is done by controlling the current input rate of the LED, as well as audible warning cancellation. Additional safety features include over-voltage protection, short-circuit protection, and transient protection.

The PS9121-F3-AX operates in a photo-transistor type configuration, with an LED in the input stage and a phototransistor in the output stage. The LED is powered by the input signal, wither DC or AC, and emits a light pulse that is detected by the phototransistor, resulting in an optically isolated output level. This opto-isolated output level can be used to control an external device such as a relay or motor.

The PS9121-F3-AX has a number of applications ideal for industrial uses such as for level sensing, conveyor controls, motor control and other similar applications. In addition, the opto-isolated output makes it an ideal choice for applications where a high degree of electrical isolation is required, such as in medical devices or in any application involving hazardous voltages.

This optoisolator can also be used in non-industrial fields, such as in home automation systems, where a reliable level of electrical isolation is needed. The PS9121-F3-AX is capable of providing a reliable optically isolated output even in extreme temperatures and environmental conditions, making it an ideal choice for use in these situations.

In short, the PS9121-F3-AX is an ideal optoisolator for a variety of business, industrial, home automation and telecommunication applications and can provide reliable optically isolated output even in extreme temperatures and environmental conditions.
