Key Differentiators: The IS230TPROH2C is a dedicated PROFINET termination board providing integrated shield termination and surge protection specifically designed for the IS220PPROH1A communication module. It offers enhanced protection against EMI and ESD in industrial environments. Unlike universal terminal boards (IS230TBTCH1B), the IS230TPROH2C is optimized for PROFINET applications with dedicated shielding connections. Compared to direct connections (without a termination board), the IS230TPROH2C provides significantly better noise immunity and maintenance convenience.

Selection Suggestions and Precautions

Selection Criteria

  • Choose the IS230TPROH2C for Mark VIe PROFINET applications requiring reliable field termination for the IS220PPROH1A communication module.

  • For applications using alternative communication protocols (PROFIBUS, Modbus TCP), use the appropriate termination board (IS230TPRFH2C, IS230TMBTH2C).

  • Ensure proper network topology (line or ring) is supported by the IS230TPROH2C.

  • Verify the cable type (CAT5e or CAT6 shielded) is compatible.

Critical Precautions

  1. Shield Termination – Properly connect cable shields to the dedicated shield termination points on the IS230TPROH2C. Ground shields at the terminal board end for PROFINET networks, following GE recommended practices.

  2. Cable Quality – Use CAT5e or CAT6 shielded twisted‑pair cables with the IS230TPROH2C. Shielded cables are strongly recommended to prevent EMI interference in industrial environments.

  3. Cable Length – Maintain Ethernet cable length within PROFINET specifications (maximum 100 meters per segment). Use switches or repeaters for longer distances.

  4. Network Topology – The IS230TPROH2C supports line (daisy‑chain) and ring (MRP) topologies. For ring topology, enable MRP and configure the redundancy manager on one switch.

  5. Terminal Connections – Use proper wire stripping length (approximately 7–8 mm). Recommended torque: 0.5–0.6 N·m. Over‑tightening may damage terminals; under‑tightening may cause intermittent connections.

  6. ESD Handling – Use grounded wrist straps when handling the IS230TPROH2C to prevent static damage.

  7. IP Configuration – The IS230TPROH2C is a passive termination board; IP configuration is performed via the IS220PPROH1A module.

  8. MRP Configuration – For ring topologies, configure MRP properly to ensure fast recovery (< 200 ms) from network breaks.

  9. Obsolescence – The IS230TPROH2C is in active production with long‑term support. For future projects requiring additional features, evaluate the IS230TPROH2D when available. Keep spare boards for critical communication applications.
