Structural Features: The unit features a compact 31mm width design. The front panel includes a detachable terminal block for field wiring and DIP switches or software settings for range selection.
Working Principle: The unit receives analog signals (voltage or current) from sensors. These signals are conditioned and converted into digital values by high-speed ADCs. The digital data is then transferred to the CPU via the backplane bus for processing.
Installation Requirements:
- Mount on CJ series CPU rack or expansion rack
- Connect field wiring to the detachable terminal block
- Use shielded cables for analog signals to reduce noise
- Separate analog signal cables from power lines
Usage Notes:
- Verify the input signal range matches the sensor output.
- Do not apply voltages exceeding the maximum rated input (±15 V).
- Ensure the unit is properly grounded to minimize noise interference.
