Atlas Copco 4230‑1705‑80 I/O Expansion Module

The Atlas Copco 4230‑1705‑80 (also known as 4230170580) is a dedicated I/O expansion module designed to augment the input/output capabilities of Atlas Copco tightening controllers, such as the Power Focus and Tensor series. This module provides additional digital and analog channels, enabling connection to a wider range of external devices like proximity sensors, solenoid valves, analogue pressure transducers, and stack lights. It is an ideal solution for complex workstations that require more than the standard built‑in I/O.

Technical Features

The module offers a mix of inputs and outputs that are fully configurable via the host controller’s software. It connects to the main controller through a high‑speed backplane or cable, depending on the model. The 4230‑1705‑80 is designed for easy installation and automatic recognition by the controller, with no additional drivers required.

Electrical Specifications

• Supply Voltage: 24 VDC (derived from controller or external)

• Digital Inputs: 8 x isolated, 24 VDC, sink/source selectable

• Digital Outputs: 8 x solid‑state, 24 VDC, 0.5 A per channel

• Analog Inputs: 2 x 0‑10 V or 4‑20 mA (software‑selectable)

• Analog Outputs: 2 x 0‑10 V (max 10 mA)

• Interface to Controller: SPI or CAN (depending on firmware)

• Protection: Short‑circuit protected outputs, input reverse‑polarity protection

• Operating Temperature: 0 °C to +55 °C

• Dimensions: 105 x 90 x 40 mm, DIN‑rail mount

Configuration and Integration

Once connected, the host controller automatically detects the module and assigns I/O addresses. Using ToolsTalk or the controller’s built‑in interface, engineers can map each channel to specific functions—e.g., start signal, part‑present sensor, or quality output. The module supports both cyclic and event‑triggered data exchange, allowing real‑time control and status feedback.

Wiring and Diagnostics

Terminal blocks are pluggable for easy wiring replacement. Each channel has a dedicated LED for status indication: green for input active, yellow for output energized, and red for fault. The module also provides diagnostic information, such as overcurrent or open‑circuit detection, which is reported to the host controller and can be used for error handling.

Compatibility

This I/O expansion module is compatible with all current Atlas Copco controllers that support external expansion, including PF3000, PF4000, PF6000, and TC‑4000 series. It can be used in combination with other expansion modules (e.g., additional I/O or communication) to build a fully customised control system.

Application Examples

Typical applications include multi‑tool stations where each tool needs its own start/stop button and OK/NOK indicator; automated lines with part present sensors and reject gates; and testing rigs where analogue pressure or flow readings are required for joint validation. The module also enables connection to external PLCs for coordinated sequences.

Installation Guidelines

Mounting is performed on a standard DIN‑rail; the module should be placed close to the host controller to minimise cable lengths. Wiring should follow the supplied terminal assignment chart, and shielding is recommended for analogue signals. The module comes with a quick‑start guide and a full manual available online.

Reliability and Maintenance

Built with solid‑state components and no moving parts, the 4230‑1705‑80 offers high reliability. It requires no regular maintenance beyond visual inspection and connection tightening. In case of failure, the module can be replaced without affecting other parts of the system.

Benefits for System Integration

By adding this I/O module, engineers can significantly expand the functionality of their tightening stations without changing the main controller. This reduces overall system cost and footprint, as only the needed I/O is added. The module’s fast response time (typically < 1 ms) ensures that signals are processed without delaying the tightening cycle.

Conclusion

The Atlas Copco 4230‑1705‑80 I/O expansion module is a practical, cost‑effective solution for enhancing the connectivity of Atlas Copco tightening controllers. Its rugged design, flexible I/O configuration, and seamless integration make it an essential accessory for advanced assembly automation.
