Working Principle:
The module continuously samples analog signals from connected field sensors. The internal analog-to-digital converter (ADC) transforms these continuous physical quantities into discrete digital values, which are then mapped to engineering units and transmitted to the AC500 CPU via the backplane I/O bus.
Installation Requirements:
- Mount securely on a standard 35 mm DIN rail.
- Connect the 24 V DC power supply ensuring correct polarity.
- Wire field sensors according to the 2-wire or 3-wire configuration guidelines in the hardware manual.
Usage Precautions:
- Always discharge static electricity before touching communication connectors.
- Do not touch the terminal base connectors or I/O bus while the system is powered.
- Ensure the CPU is in STOP mode when initially configuring the module parameters.
