W2-S70 BENDER

W2-S70 BENDER Output Module

Product  Description：

Bender Output Modules are high-reliability components designed to interface with Bender’s core monitoring systems, such as insulation monitoring devices (IMDs) and residual current monitors (RCMs). These modules convert internal digital data, alarm states, and measured values into physical outputs, including relay contacts, analog currents, or fieldbus network protocols. They act as the critical communication and signaling link, ensuring that system faults or insulation degradation are immediately communicated to external control systems, sirens, indicator lights, or supervisory software.

Product Parameters

The technical characteristics of Bender Output Modules are optimized for signaling accuracy and system integration:

• Output Types: Configurable with multiple Form C (changeover) dry relay contacts, solid-state relays, or continuous analog outputs such as 0-20mA and 4-20mA.

• Contact Ratings: Relay contacts typically support switching currents up to 5A or 8A at 250V AC or 30V DC, making them suitable for directly driving heavy-duty alarm horns or trip coils.

• Supply Voltage Options: Flexible power input configurations, usually supporting 24V DC or universal AC/DC supplies ranging from 100V to 240V.

• Response Time: Ultra-fast relay activation, often occurring within a few milliseconds of a threshold violation to ensure rapid hazard mitigation.

• Isolation Voltage: High galvanic isolation between the internal logic side, the auxiliary power supply, and the output contacts, typically rated up to 4kV.

• Enclosure and Mounting: Compact modular housing designed for standard 35mm DIN rail installation, featuring finger-safe screw or spring-clamp terminals.

Product Advantages

Bender Output Modules offer distinct operational advantages, particularly in safety-critical electrical systems:

• Failsafe Configuration: Relays can be configured for N/O (normally open) or N/C (normally closed) operation, allowing for "failsafe" logic where an unpowered or broken module automatically triggers a system alarm.

• Flexible Signal Mapping: Allows users to map specific internal faults—such as pre-warnings, critical insulation faults, or device errors—to independent individual output relays.

• Seamless Scalability: Multiple output modules can be connected to a single central monitoring device via a proprietary bus system (like the Bender BMS bus), expanding the system's signaling capacity easily.

• Robust Signal Integrity: High-grade mechanical and electrical isolation protects connected PLC systems or building management networks from dangerous surges occurring on the monitored power grid.

• Local Diagnostic Feedback: Features individual text-free status LEDs for each output channel, allowing plant operators to verify the active state of each output loop instantly.

Product Applications

These modules are widely utilized to provide warning and tripping signals across various industries:

• Healthcare and Hospitals: Activating remote indicator panels and acoustic alarms in medical IT systems (isolated power groups) within operating theaters and intensive care units.

• Industrial Manufacturing: Interfacing with plant PLCs to automatically shut down variable speed drives or conveyor systems when an insulation fault poses a fire hazard.

• Renewable Energy Installations: Signalling grounding faults in massive solar photovoltaic arrays and wind turbine power conversion systems to the main SCADA control room.

• Maritime and Offshore: Transmitting insulation health status from ungrounded shipboard power systems to the central bridge monitoring computer.

• E-Mobility Infrastructure: Operating trip mechanisms in DC fast-charging stations to disconnect power safely if isolation between the vehicle and charger is compromised.

Important Precautions

To maintain safety standards and prevent premature hardware failure, the following precautions must be observed:

• Contact Load Limits: Never exceed the absolute maximum voltage or current ratings specified for the relay contacts. Switching inductive loads without external surge suppression can cause contact welding.

• Failsafe Configuration Logic: Carefully verify whether the software and hardware are set to operation with or without fault memory. Incorrect configuration can lead to alarms clearing themselves before maintenance teams can locate the fault.

• Power Separation: Ensure that external cables carrying high-voltage AC lines to the relay contacts are routed away from low-voltage data cables to avoid inductive noise coupling.

• Dead-System Handling: Before working on the module terminal blocks, verify that both the module's auxiliary power supply and any external voltages routed through the relay contacts are completely disconnected.

• Ambient Atmosphere Protection: If installing the module in environments with heavy chemical vapor, salt spray, or conductive dust, always place the module inside a sealed enclosure with an appropriate IP rating.
