Characteristics of terminal blocks

Using the existing track-type terminal frame screw connection technology, and adding a circuit composed of electronic components, the transmission coupling of the photoelectric process is realized.

The core of automatic control is that the control unit must be reliably isolated from the sensors and actuators to avoid interference. Voltage matching, it can also be used as an interface element between process control peripherals and control, signal and regulator devices, and is suitable for different voltage and power ranges.

Optical isolation terminals have the advantages of low control terminal signal loss, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, not afraid of vibration, not affected by position and long life, so they are widely used in the field of automatic control.
