LINETRAXX® RCMS460 / RCMS490

Product catalog summary

Product Overview
The LINETRAXX® RCMS460/RCMS490 are advanced multi-channel residual current monitors suitable for earthed AC, DC, and AC/DC systems (TN and TT systems). They are designed to detect AC, pulsed DC, and AC/DC currents, with models RCMS460-D/-L and RCMS490-D/-L capable of monitoring up to 1080 channels via a BMS bus.

Specifications
- 12 measuring channels per device.
- Compatible with various measuring current transformers.
- Fast scanning time of ≤180 ms.
- Two response values with separate alarm relays.
- History memory for 300 records and data logger for 300 records per channel.
- True RMS value measurement and harmonics analysis.
- Optional sensitivity to AC, pulsed DC, or AC/DC currents.

Applications
- Monitoring residual, fault, and rated currents (0…2000 Hz).
- Fire hazard monitoring in flammable environments.
- EMC monitoring of TN-S systems.
- Monitoring N and PE conductors for overload and current-free status.
- Personnel and fire protection through rapid disconnection.

Device Features
- Backlit graphical display and alarm LEDs.
- Data exchange via BMS bus with password protection.
- Continuous CT connection monitoring.
- RoHS compliant.

Functionality
The devices measure currents as true RMS values, displaying them on an LC display. Alarm relays activate if response values are exceeded. Devices can be tested via a test button, with parameters set through the display or connected panels.

Device Variants
- RCMS460-D: Detailed local display.
- RCMS460-L: Two-digit display for device address.
- RCMS490-D/L: Includes galvanically isolated alarm contact.
- RCMS-D4/L4: For current measurements with type A transformers.

Standards and Approvals
- Complies with DIN EN 62020 (VDE 0663):2005-11.
- Meets UL508 and UL1053 standards for industrial control equipment.

Wiring and Connections
Specific wiring configurations are required for power supply, measuring current transformers, and external test/reset buttons, with detailed connection instructions provided.

Frequency Settings
Adjustable frequency response for fire, personnel, or plant protection, with specific settings for different protection types.

System Design Examples
- Minimum System: RCMS460-D with 12 measuring points.
- Standard System: RCMS460-D, RCMS460-L, and protocol converter COM465IP.

Specifications
- Insulation Coordination: Adheres to IEC 60664-1/IEC 60664-3 standards.
- Measuring Circuit: Uses external transformers from CTAC, WR, WS, WF, CTUB100, and CTBS25 series.
- Inputs/Outputs: Includes test/reset buttons and RS-485/BMS interface.
- Environmental Conditions: Operating temperature from -25 to +55 °C, EMC compliant to DIN EN 62020.

Components and Accessories
- Power Supply Units: Various models for different CTUB100 series transformers.
- Condition Monitors: COM465IP with multiple function packages.
- Measuring Current Transformers: Available in various types and sizes.

Ordering Information
