IRDH375-425 BENDER

IRDH375-425 BENDER analog module

Product  Description：

Bender analog modules are high-precision industrial components designed to interface specialized electrical safety monitoring systems, such as insulation monitoring devices (A-ISOMETER) and residual current monitors (RCMS), with central control systems, PLCs, or building management networks. These modules function by converting measured physical variables, such as insulation resistance in ohms or leakage current in milliamperes, into standardized analog current or voltage signals, enabling continuous safety logging and real-time threshold tracking.

Product Parameters

The technical framework of a Bender analog module centers on signal precision, isolation, and standard industrial ratings:

• Analog Output Signals: Selectable or dedicated configurations for standard loops, typically supporting 0-20mA, 4-20mA, 0-10V, or 2-10V DC outputs.

• Input Signal Adaptation: Engineered to receive digital data or proprietary measurement inputs directly from Bender core safety monitors over an internal device bus.

• Linearity and Accuracy: High-fidelity signal translation with an accuracy error margin usually limited to less than 1 percent of the full-scale value.

• Isolation Voltage: Robust galvanic isolation between the measurement input side, the analog output side, and the supply power, commonly rated at 2kV AC or higher.

• Power Supply Requirements: Operates flexibly on standard auxiliary power configurations, including 24V DC, 115V AC, or 230V AC depending on the specific module variants.

• Mounting and Enclosure: Designed for compact control cabinet environments, featuring standard 35mm DIN rail mounting with an IP20 protection rating.

Product Advantages

Bender analog modules provide critical enhancements to industrial safety and diagnostic capabilities:

• Seamless Automation Integration: Converts specialized insulation and residual current data into standard industrial signals, allowing any third-party PLC or SCADA system to monitor electrical safety parameters without proprietary drivers.

• High Noise Immunity: Advanced filtering circuitry ensures that the analog output remains stable and accurate even when operating near heavy electrical noise sources like variable frequency drives.

• Proactive Fault Detection: By providing a continuous analog trend rather than just a simple binary alarm switch, these modules allow engineers to identify gradual insulation degradation before a catastrophic system trip occurs.

• Compact Control Panel Footprint: The slim modular design takes up minimal space on the DIN rail, facilitating easy retrofitting into existing electrical distribution panels.

• Enhanced Electrical Isolation: The high galvanic isolation prevents dangerous ground fault currents on the power monitoring side from damaging sensitive low-voltage automation equipment.

Product Applications

These modules are utilized across industries where electrical uptime and preventative maintenance are critical:

• Hospital Power Systems: Transmitting insulation resistance values from isolated power structures in operating rooms to central nursing stations and engineering monitors.

• Renewable Energy Generation: Monitoring the insulation status of large photovoltaic arrays and wind turbine generators, feeding real-time safety data back to the main control room.

• Industrial Manufacturing: Interfacing with residual current monitors on automated production lines to track leakage current trends in large motor networks.

• Marine and Offshore Engineering: Providing continuous insulation data to shipboard management systems on ungrounded IT electrical systems used in vessels and drilling rigs.

• E-Mobility Charging Infrastructure: Integrating safety telemetry into commercial electric vehicle charging stations to monitor continuous ground insulation integrity.

Important Precautions

To preserve measurement accuracy and safeguard the hardware, technicians must comply with the following operational rules:

• Load Impedance Matching: Ensure that the total loop resistance connected to the analog output does not exceed the module's specified maximum load limits, as excessive resistance will clip the signal and cause inaccurate readings.

• Separate Signal Routing: Run the analog output lines through dedicated low-voltage wire ways. Do not route these sensitive signal lines parallel to high-current power cables to prevent inductive noise interference.

• Shielding Practices: Use shielded twisted-pair cabling for the analog output loop. Connect the cable shield to the ground at a single point, preferably at the receiving control system side, to avoid ground loops.

• Auxiliary Supply Verification: Double-check the auxiliary power rating before energizing the module. Applying high-voltage AC to a dedicated DC module will cause permanent component destruction.

• Safe Terminal Maintenance: Always isolate the external power supplies before making wiring adjustments or replacing a module to avoid accidental short circuits or electrical shock hazards.
