Eaton CAN-16DO/0.5A-PK – 16-Channel Digital Output Module with CANopen

The Eaton CAN-16DO/0.5A-PK (catalog number 140254) is a compact, intelligent remote I/O module designed for distributed automation architectures. Part of Eaton’s XC series expansion modules, it communicates via CANopen protocol, making it easy to integrate with Eaton PLCs, motion controllers, or third-party master devices. With 16 digital outputs rated at 0.5 A per channel, it can directly drive small actuators, indicator lights, contactors, and relay coils.

Designed for Distributed Control

In modern machine design, placing I/O close to sensors and actuators reduces cabling and simplifies maintenance. The CAN-16DO/0.5A-PK is housed in a rugged IP20 enclosure suitable for control cabinet installation. Its spring‑clamp terminals (Push-in technology) allow fast and vibration-resistant wiring without special tools.

Key Features

• 16 Digital Outputs: Transistor outputs (PNP, 24V DC) with short-circuit and overload protection per channel.

• High Output Current: 0.5 A per channel, 4 A total per module (continuous).

• CANopen Interface: Supports CiA DS301 V4.0.1, with data rates up to 1 Mbit/s. Easy addressing via rotary switches.

• Diagnostic LEDs: Per-channel status indication and module power/communication error LEDs.

• Electrical Isolation: Between CAN bus and I/O channels for robust operation in industrial environments.

Technical Specifications

• Output Type: Solid-state (high-side switch), 24 V DC nominal

• Output Current: 0.5 A per channel, resistive load; total current limited

• Protection: Short-circuit, over-temperature, and reverse polarity protection (supply)

• Power Supply: 24 V DC (20.4...28.8 V) for module electronics and output load

• Communication: CANopen, galvanically isolated, terminating resistor selectable

• Connection: Push-in terminals for wire sizes 0.2...1.5 mm² (AWG 24...16)

• Dimensions (WxHxD): Approximately 50 x 120 x 70 mm

• Environmental: Operating temperature 0°C to +55°C, storage -25°C to +85°C

Applications

The CAN-16DO/0.5A-PK is widely used in:

• Material handling systems – controlling stack lights, solenoid valves, and motor starters

• Packaging machines – activating gluing units, cutters, and reject gates

• Automotive assembly lines – driving pneumatic valves and indicators

• Process control – remote on/off control of pumps and fans

Easy Integration with Eaton Systems

When used with Eaton’s XC-CPU or XV-102 PLCs, the CAN-16DO/0.5A-PK can be configured via the engineering software (e.g., CODESYS) using standard CANopen device description files (EDS). The module supports synchronous and asynchronous output modes, as well as heartbeat and node guarding for network reliability. Its compact size allows multiple modules to be placed side by side, creating a scalable I/O station.

With its robust design and compliance with industrial standards, the Eaton CAN-16DO/0.5A-PK (140254) provides a dependable solution for expanding the digital output capacity of any CANopen-based control system.
