Product Introduction

The ABB 1SFB527068D7084 is a high-performance safety relay module designed to monitor and control safety-related functions in industrial automation systems. As a critical component in ensuring workplace safety, it is engineered to detect hazardous conditions and initiate protective actions, such as stopping machinery or activating alarms, to prevent accidents.

This module features 2 safety inputs (normally closed) for connecting devices like emergency stop buttons, safety gates, and light curtains, and 2 safety outputs (normally open) to control contactors, valves, or other actuators. With a SIL 3 rating and PL e performance level, it meets stringent safety standards, making it suitable for use in high-risk industrial environments. When integrated with communication adapters like the ABB 64606859 RPBA-01 in larger systems, it can provide safety status data to the control network, enhancing overall system visibility and control.

Core Advantages and Technical Highlights

High Safety Integrity

The ABB 1SFB527068D7084 achieves SIL 3 and PL e ratings, ensuring it can reliably perform safety functions in high-risk applications. This means it has a very low probability of failure on demand, making it suitable for protecting personnel and equipment in environments where even a single failure could have severe consequences. For example, in a robotic welding cell, the module monitors the safety gate interlock; if the gate is opened during operation, it immediately triggers the robot to stop, preventing access to the hazardous area.

Fast Response Time

With a response time of ≤ 15 ms, the ABB 1SFB527068D7084 can quickly detect safety input signals and activate the safety outputs, minimizing the time between a hazardous event and the protective action. This rapid response is crucial in applications where machinery operates at high speeds, such as in packaging lines or conveyor systems. When an emergency stop button is pressed, the module reacts instantly to cut power to the drive, reducing the risk of injury.

Robust and Reliable Design

Built to withstand harsh industrial conditions, the ABB 1SFB527068D7084 operates within a wide temperature range (-25°C to +70°C) and features a compact, rugged housing. Its reliable switching mechanism ensures consistent performance over time, even with frequent operation. The module also includes diagnostic functions that monitor input and output status, providing early warning of potential faults and enabling proactive maintenance.

Typical Application Scenarios

In automotive manufacturing plants, the ABB 1SFB527068D7084 is used to monitor emergency stop buttons and safety gates around robotic assembly stations. The safety inputs are connected to the emergency stop circuit and gate interlocks, while the safety outputs control the contactors powering the robots. If a worker presses an emergency stop button or opens a safety gate, the module immediately de-energizes the outputs, stopping the robot. In larger systems, the safety status can be communicated to the main control network via the ABB 64606859 RPBA-01 adapter, allowing operators in the control room to monitor safety events in real-time.

In food processing facilities, the module is employed to safeguard workers around mixing machines and slicing equipment. It connects to light curtains that detect when a hand or object enters the hazardous area of the machine. Upon detection, the ABB 1SFB527068D7084 triggers the machine to stop within milliseconds, preventing injuries. Its ability to operate in high-temperature environments (up to +70°C) makes it suitable for use near ovens or sterilization equipment, where ambient temperatures may be elevated.

In logistics and material handling systems, the ABB 1SFB527068D7084 monitors safety interlocks on conveyor belt systems. It ensures that if a section of the conveyor is opened for maintenance, the entire system downstream is stopped to prevent material from piling up or workers from being exposed to moving parts. The module’s compact design allows it to be installed in tight control cabinets alongside other components like the ABB 64606859 RPBA-01, facilitating integration into existing automation networks.

Installation, Commissioning and Maintenance Instructions

Installation Preparation

Before installing the ABB 1SFB527068D7084, ensure the mounting location is clean, dry, and free from excessive vibration. The ambient temperature should be within -25°C to +70°C, with relative humidity below 95% (non-condensing). Required tools include a screwdriver (PH2) and torque wrench (set to 0.5 – 0.7 Nm for terminal connections). Mount the module on a 35 mm DIN rail, ensuring it is securely fastened. Connect the 24 V DC power supply, ensuring correct polarity. Wire the safety inputs to the safety devices (e.g., emergency stop buttons) and the safety outputs to the load (e.g., contactor coils), following the wiring diagram provided in the user manual. Use twisted-pair cables for inputs to minimize electromagnetic interference.

Commissioning Steps

After installation, perform a functional test to verify the module’s operation. Press the emergency stop button or open the safety gate to ensure the safety outputs de-energize (contacts open) within the specified response time. Reset the module (either manually or automatically, depending on configuration) and confirm that the outputs energize (contacts close) when the safety condition is restored. Use a multimeter to check voltage levels at the input and output terminals, ensuring they are within the specified ranges. Verify that the module’s status indicators (power, safety status) function correctly, providing clear visual feedback.

Maintenance Suggestions

For daily maintenance of the ABB 1SFB527068D7084, visually inspect the module and connections for damage, corrosion, or loose wires. Clean the module’s surface with a soft, dry cloth to remove dust. Test the safety functions regularly (as per site safety procedures) by activating the connected safety devices and confirming that the outputs respond correctly. Check the status indicators to ensure they reflect the module’s operational state. If a fault is detected (e.g., outputs fail to respond), first check the wiring and connected devices; if they are functional, replace the module with an ABB-approved spare part. It is recommended to keep a log of maintenance activities and test results to track the module’s performance over time.
