Product Description
145988-02 BENTLY NEVADA Redundant Power Supply Module 5 V DC/3 A 12V DC
145988-02 Description
The 145988-02 is a high-reliability, dual-channel relay output module engineered for integration within industrial machinery protection and condition monitoring systems. Designed as a compact, rack-mountable interface component, it functions as a critical signal actuator, converting system-level alarm and shutdown commands into isolated, fail-safe electrical switching actions for external control circuits. This module provides two independent, optically isolated single-pole double-throw (SPDT) relay outputs, engineered for dependable operation in extreme industrial environments where precision, isolation, and long-term stability are essential for safeguarding critical rotating equipment and process systems.
145988-02 Key Features
- Dual Independent Relay Channels: Two fully isolated SPDT relay outputs for separate alarm, warning, or shutdown control functions.
- High-Galvanic Isolation: Optoelectronic isolation between input logic, relay channels, and external loads for superior noise immunity and system protection.
- Fail-Safe Operation: Configurable for normally energized (de-energize to trip) or normally de-energized (energize to trip) logic to meet diverse safety interlock requirements.
- Wide Load Compatibility: Supports a broad range of AC and DC control voltages and load types for versatile industrial integration.
- Compact Rack-Mount Form Factor: Slim, half-height design for efficient use of standard monitoring system rack space, supporting hot-swap capability.
- Front-Panel LED Diagnostics: Clear LED indicators for power status and individual channel relay state for quick visual troubleshooting.
- Industrial-Grade Durability: Sealed, rugged construction resistant to vibration, shock, dust, and oil mist common in heavy industrial settings.
- Long Electrical Life: High-quality relay contacts rated for extended mechanical and electrical switching cycles.
- Reverse Polarity & Overvoltage Protection: Built-in circuit protection safeguards against wiring errors and electrical transients.
- Universal Power Compatibility: Operates from a wide-range DC power supply for seamless system integration.
- Global Safety & EMC Compliance: Fully certified to meet international industrial standards for safety, electromagnetic compatibility, and environmental resilience.
145988-02 Materials & Applications
