Description

ABB 87TS01 GJR23600R1545

Core Functions and Features

Safety Logic Processing

• Input Channels: 4 safe digital inputs, supporting 24V DC signals (e.g., emergency stop buttons, safety light curtain signals), with dual-channel redundancy design (dual-channel mutual inspection);
• Output Channels: 2 safe relay outputs (normally open + normally closed contacts), contact capacity 250V AC/10A, supporting forced disconnection in case of failure (Fail-Safe);
• Logic Functions: Supports AND/OR safety logic operations, configurable as "dual-channel input-single-channel output" or "cross-monitoring" mode.

Fault Diagnosis and Redundancy Design

• Self-Diagnosis Function: Real-time monitoring of short-circuit and open-circuit faults in input/output loops, with a diagnostic coverage rate ≥99%;
• Redundancy Mechanism: Input channels adopt "2oo2D" (dual channels fail only when both fail) design, meeting safety integrity level requirements;
• Status Indication: LED lights display power, input, output, and fault status for on-site maintenance.

Technical Parameters

Application Scenarios

Machine Tool Safety Control

• Accesses emergency stop button and safety door switch signals, quickly cuts off the main shaft motor power when abnormalities are detected, and outputs alarm signals to the PLC.

Safety Monitoring of Packaging Production Lines

• Monitors the status of two-hand control buttons to ensure that equipment is only allowed to start when operators' hands are away from dangerous areas, preventing mechanical injuries.

Emergency Shutdown System for Petrochemical Industry

• Cascades multiple safety relay modules to build a redundant ESD (Emergency Shutdown System), triggering plant-wide shutdown when dangers such as leaks and overpressure are detected.

Installation and Configuration Key Points

Wiring Specifications

• Use twisted-pair shielded cables for input signals, with a grounding resistance ≤1Ω, and avoid parallel laying with power cables (spacing ≥30cm);
• Output contacts need to be connected in series with fuses (recommended 5A) to prevent relay damage from short circuits.

Safety Loop Design

• Follow the principle of "dual-channel + cross-monitoring", and input signals must come from independent sensors (such as dual emergency stop buttons);
• Use ABB Safety Tool software to configure logic functions and generate safety loop verification reports.

Maintenance and Testing

• Perform regular functional tests (e.g., once a month), and verify the normalcy of output response by forcing input signals;
• If the fault light (FAULT LED) is on, check for loose wiring or read fault codes through the diagnostic interface (e.g., 0x10 indicates input open circuit).
