SI99: Signal Isolator

- Intrinsically safe isolation without
  power supply

- Eliminating ground-loop

- 2 channels available

- High accuracy and stability
General Features and Benefits: 

Intrinsically safe isolation without power supply

Eliminating ground-loop

2 channels available

High accuracy and stability

            The WISCO Signal Isolator SI99 is a WISCO Industries product designed to break the galvanic path between a transmitted signal source and a receiving device, such as a controller or recorder. The Signal Isolator solves the problem of transferred signal distortion due to ground potential differences. The Signal Isolator is highly effective in eliminating unreliable or inaccurate signal transfer by providing total current-to-current signal isolation. The Signal Isolator derives its operating potential from the existing input loop current and, therefore, does not require a dedicated power supply. The Signal Isolator is placed in series with the drive signal and provides and output current that is proportional to the input signal current.

            When a signal isolation device is installed it is important to consider the voltage drop or additional line resistance that will be placed in the system. Any additional load tends to reduce the line or drive potential and may exceed the source rating. The effect of voltage drop within the system must be calculated to ensure that drive capability is not exceeded. The Signal Isolator features a maximum fixed voltage drop of 2.5 VDC (4.2 V for 10 - 50 mA) which remains constant over the entire temperature range of 0 °C to 50 °C

            ลักษณะการใช้งานของ Signal Isolator

            1) ป้องกันการเกิด Ground Loops ซึ่งเป็นสาเหตุ ทำให้ค่าวัดไม่คงที่ หรือผิดจากความเป็นจริง

           2) ป้องกันความเสียหายที่จะเกิดขึ้นกับ PLC หรือ DCS เนื่องจากสัญญาณรบกวนที่เกิดขึ้นทางด้าน Transmitter เช่น ฟ้าผ่า หรือจาก A.C. Line โดยตัว Signal Isolator ทำหน้าที่เหมือนกำแพงที่ป้องกัน ไม่ให้สัญญาณเหล่านี้ ส่งเข้าไปทำความเสียหายให้ PLC หรือ DCS ได้
