Product Introduction

Model Explanation

• 1SAP214000R0001: ABB standard part number.

• TU508-ETH:

  • TU = Terminal Unit

  • 508 = Ethernet interface base for S500

Interface and Communication

• 2×RJ45 Ethernet ports: Support PROFINET, EtherCAT, Modbus TCP, EtherNet/IP.

• Spring‑cage terminals for field power and signal wiring.

• Backplane connector for S500 communication modules; internal bus and 24 V DC power distribution.

• Connects to AC500 internal bus for PLC‑to‑Ethernet data exchange; plug‑and‑play, no config needed.

Core Functions

• Secure mounting and reliable spring‑cage connection for S500 Ethernet communication modules.

• Dual RJ45 ports: Enable daisy‑chain Ethernet networking for distributed I/O.

• Tool‑free spring terminals: Fast wiring, suitable for vibration‑prone environments.

• Supports hot swap of communication modules to reduce downtime.

• Stable 24 V DC power and bus signal distribution; built‑in EMC protection for harsh industrial environments.

Application Scenarios

• ABB AC500 PLC + S500 I/O systems requiring Ethernet communication.

• Factory automation: production lines, packaging machinery, material handling (PROFINET/EtherCAT).

• Process automation: water treatment, HVAC, energy management (Modbus TCP).

• Distributed I/O networks: remote sensor/actuator connection via Ethernet.

• New AC500 deployments and legacy system upgrades with Ethernet connectivity.

Usage and Maintenance

• Mount on DIN rail in cabinet; ensure ventilation, dryness, no direct sunlight.

• Connect 24 V DC with correct polarity.

• Insert S500 Ethernet module into TU508‑ETH and lock.

• Wire field cables to spring terminals: open lever, insert wire, close lever.

• Connect Ethernet cables to RJ45 ports for network communication.

• Periodically check terminal connections, RJ45 contacts, and dust; clean as needed.

• Use only compatible S500 Ethernet modules; avoid over‑forcing spring structures.

• Troubleshoot: check power, connections, and Ethernet link status first; replace base if damaged.
