ISOMETER® isoHR685W-x-I-B

Product catalog summary

Product Overview
The ISOMETER® isoHR685W-x-I-B is an insulation monitoring device for IT AC and DC systems, including those with rectifiers and inverters. It features isoData for logging and ISOsync for capacitive coupled systems.

Specifications
Compliant with IEC 61557-8, suitable for AC, 3(N)AC, AC/DC, and DC systems. It includes a high-resolution graphical LC display for parameter settings and measurements.

Functionality
Monitors insulation resistance, triggering alarms if thresholds are breached. Utilizes a micro-controlled circuit for measuring current, with settings stored in a fail-safe memory.

Device Features

Automatic adaptation to system leakage capacitance
Adjustable response value ranges (1 kΩ to 3 GΩ)
Graphical insulation resistance representation over time
History memory for alarm messages with timestamps
Remote setting and diagnosis
Supports Modbus TCP and RTU protocols

Operating Elements
Includes LEDs for power, service, and alarms, a display for measurements, and navigation buttons.

Interfaces
Supports Modbus TCP, Modbus RTU, and BCOM, with an integrated web server for settings.

Device Variants
Available in two variants: isoHR685W-D-I-B with a display and isoHR685W-S-I-B without a display.

Measurement Method
Uses AMPPlus method, suitable for systems with high leakage capacitances.

Standards and Certifications
Complies with DIN and IEC standards for performance and safety.

Wiring and Installation
Includes wiring diagrams and recommendations for protection and short-circuit prevention.

Accessories and Ordering Information
Offers various accessories and specifies device configurations and part numbers.

Additional Specifications
Measures insulation resistance from 0.1 kΩ to 10 GΩ with ±15% uncertainty. Features a 127 x 127 pixel graphic display.

LED Indicators
Includes green LED for operation, yellow LEDs for service, alarm 1, and alarm 2.

Inputs and Outputs
X1 interface supports up to 10 m unshielded and 100 m shielded cables. Provides 1 A per output, 200 mA total, with three digital inputs and two outputs.

Analogue Output
One analogue output with linear mode, supporting current and voltage outputs.

Interfaces
Supports web server/Modbus TCP/BCOM with 10/100 Mbit/s data rate, handling up to 100 Modbus requests per second.

Environmental and Mechanical Conditions
Operates from -25 to +55 °C, suitable up to 3000 m altitude, compliant with IEC standards.

Connection and Mounting
Uses pluggable screw or push-wire terminals, designed for DIN rail mounting.

Protection and Compliance
Internal protection IP40, terminal protection IP20, complies with EMC standards IEC 60533 and IEC 61326-2-4.

Additional Features
"W" option offers increased shock and vibration resistance, with varnished electronics for protection.
