Designed for the Procontic and early Advant series, this module acts as a bus master or slave interface to ensure real-time transmission of digital and analog signals across distributed automation networks. Its compact, rail-mounted design and low power consumption make it an efficient solution for expanding legacy industrial control architectures without requiring significant cabinet space.

Model Comparison
The DT602 (GJR2911200R1) is a dedicated interface unit, whereas similar models like the DT601 often lack the enhanced diagnostic capabilities found in the 602 series. While the GJR2911200R1 is the standard industrial version, some “R” variants may differ in their coating (e.g., tropicalized for high humidity). Compared to the newer CI590 modules from the AC500 series, the DT602 is specifically built for legacy CS31 bus architectures, meaning it utilizes older RS-485 physical layers that are not directly compatible with Ethernet-based fieldbus protocols without a dedicated gateway.
Operation Tips
- Address Configuration: Ensure the station address is correctly set via the rotary or DIP switches before powering the system; duplicate addresses on the CS31 bus will cause communication collisions.
- Termination Resistors: Always check that the last module on the CS31 bus line has its termination resistor enabled to prevent signal reflection and data corruption.
- Shielding: Use shielded twisted-pair cables for the bus connection and ensure the shield is properly grounded at the entry point to minimize electromagnetic interference.
- Hot-Swapping Warning: Avoid removing or inserting the DT602 module while the bus is active or the power is on, as this can cause temporary bus failure or damage to the internal logic circuits.
