Function

Safe input/output

It provides 8 safety inputs for connecting safety devices and supports current immersion configuration.

It provides 8 solid-state safety outputs for driving safety loads (such as relays and actuators), and supports current source output configuration.

Four test outputs are used for sensor or load testing to ensure the functional integrity of the input device.

DeviceNet Security Protocol:

Communicate with the Safety controller through the DeviceNet network using the CIP Safety protocol to provide high-speed and reliable safety data transmission.

Support distributed I/O architecture to reduce wiring complexity.

Self-diagnostic function:

It is equipped with an internal self-diagnostic function, which is executed regularly when the module is powered on and during operation to detect internal errors.

In the event of a fatal error, the module status indicator light turns red, and the safe output and input data are automatically turned off to ensure system safety.

Configuration lock

Support configuration lock function to prevent unauthorized configuration changes and enhance system security.

Status monitoring

High security level:

Complies with SIL 3 and Category 4 standards and is suitable for applications that require high safety integrity.

Support dual-channel logical monitoring for security devices to detect time differences between channels to ensure reliability.

Compact design

Adopting the CompactBlock design, it is suitable for installation in cabinets with limited space, and the DIN rail installation simplifies deployment.

Application scenarios

Safety control system

It is used to connect emergency stop buttons, safety light curtains, door switches and other devices, control safety relays or actuators, and ensure the safety of personnel and equipment.

It is applicable to manufacturing industries (such as automobiles and food processing) to prevent operators from coming into contact with dangerous areas.

Distributed I/O architecture: In large factories or production lines, distributed secure I/O is implemented through the DeviceNet network, reducing the cost of long-distance wiring. It is suitable for robots, conveyor belts or packaging equipment.

Process industry: In the chemical, oil and gas, or pharmaceutical industries, monitor and control safety-critical equipment (such as valves and pumps) to ensure compliance with SIL 3 and Category 4 requirements.

Material handling: In warehousing or logistics systems, control safety doors, sensors or actuators to ensure the safe operation of automated sorting or conveying systems.

Energy management: Managing safety switches or monitoring devices in power distribution or renewable energy systems to protect equipment and operators.

Legacy system upgrade: Maintain or upgrade the PLC-5 or GuardLogix system based on DeviceNet, and integrate security functions to meet modern security standards.
