SICK UE23-2MF2D3 Used Working Safety Relay

Product Overview

The SICK UE23-2MF2D3 is a compact and reliable Safety Relay Module from the UE23 series, specifically designed for the evaluation of safety signals in industrial environments. This dual-channel device is commonly used for monitoring emergency stop buttons, safety switches, and interlocking devices, providing a critical fail-safe interface between safety sensors and a machine's power control circuit. As a Used Working unit, this relay offers a high-performance solution for ensuring compliance with international safety standards such as Cat. 3 (EN ISO 13849-1) and SIL 2 (IEC 61508) in a space-saving DIN rail format.

Key Features

• Dual-Channel Evaluation: Capable of monitoring 1 or 2-channel safety circuits with cross-circuit detection to prevent unintended startups.
• Safety Relay Outputs: Features 2 normally open (NO) safety contacts and 1 normally closed (NC) auxiliary contact for status feedback to a PLC.
• Automatic or Manual Reset: Offers flexible configuration for either automatic restart or supervised manual reset via a start button.
• Compact 22.5mm Housing: The slim "Tower" design allows for high-density installation in electrical cabinets, maximizing rail space.
• Fast Response Time: Features a short response time of ≤ 80 ms, ensuring hazardous movements are stopped rapidly upon a safety breach.
• Diagnostic LEDs: Equipped with front-panel LED indicators for Power, Input 1, and Input 2, facilitating instant on-site troubleshooting.
• Wide Voltage Tolerance: Designed to operate reliably on 24V AC/DC power supplies with robust internal protection against voltage spikes.

Item Condition (Used Working)

• Functional Status: Used Working. This safety relay has been professionally bench-tested. Both input channels and all safety output contacts have been verified for correct switching and timing.
• Physical State: Clean industrial condition. The plastic housing and DIN rail locking mechanisms are intact. The screw terminals are in excellent condition with no signs of arcing.
• Technical Integrity: The internal relays are free of contact welding. The unit has been cleared of any industrial debris and handled in an ESD-safe environment.
• Note: Professional installation by a qualified safety technician is mandatory. Please verify that the safety category of this device matches your specific machine risk assessment.
