Working Principle: The module receives digital values from the PLC CPU via the backplane bus. A 12-bit digital-to-analog converter (DAC) on each channel translates the digital word into a proportional analog voltage or current. The output stage uses precision op-amps and current-sinking/sourcing transistors to drive the load. Channel-to-logic isolation is achieved through opto-isolators, ensuring noise immunity and protecting the CPU from field-side faults. The software configuration (voltage vs. current mode) is set via the CPU programming software (Proficy Machine Edition or CIMPLICITY). Installation Requirements:
- Must be installed in an IC200-compatible chassis (IC200CHS002 or similar)
- Requires a 5V DC power supply module (such as IC200PWR102B) in the same rack
- Terminal wiring: Use shielded twisted pair cables for analog signals
- Ground the shield at one end only to avoid ground loops
- Maximum cable length: 300 meters (depending on cable quality and noise environment)
- Ensure proper ventilation; maintain at least 10mm clearance above and below the module
Usage Notes:
- Never exceed 24V DC on voltage output channels — this will permanently damage the module
- When using current output mode, ensure the loop resistance does not exceed 600 ohms
- Calibrate outputs annually or after any firmware update
- Avoid running analog signal cables parallel to high-power cables (maintain minimum 150mm separation)
- Use software filtering (moving average or low-pass filter) to reduce noise on critical applications
