Basler Electric BE10493002 Protection and Auxiliary Module
The Basler Electric BE10493002 is a specialized protection and auxiliary module engineered to complement generator control and protection systems. It serves as an interface and logic element between primary protective relays and circuit breaker control circuits, enhancing the overall reliability and flexibility of power system protection schemes. This module is part of Basler Electric's extensive line of auxiliary devices that support safe and efficient generator operation.
Functional Overview
The BE10493002 provides multiple functions including contact multiplication, signal conditioning, and timing logic. It is typically used in conjunction with overcurrent, differential, or voltage relays to expand output contacts or to introduce programmable logic delays. The module accepts input signals from protective relays and generates corresponding outputs to trip breakers, initiate alarms, or block other protection elements. Its solid-state design ensures fast response and high immunity to electrical noise.
Key Features
Solid-state circuitry for high reliability and long service life
Multiple independent output contacts for tripping and signaling
Adjustable time delays for coordination with other protection devices
Optically isolated inputs to prevent ground loops and interference
Wide auxiliary power supply range for compatibility with station batteries
Compact panel-mount design suitable for switchgear and control cabinets
LED status indicators for power and output activation
Complies with ANSI C37.90 and IEC 60255 standards
Technical Specifications
The BE10493002 operates on a nominal DC supply of 24 to 250 VDC or AC supply of 120 to 240 VAC, 50/60 Hz. Input circuits are rated for standard dry contact or solid-state relay signals. Output contacts are rated for 10 A at 250 VAC/30 VDC for resistive loads. Time delay settings are adjustable from 0.05 to 10 seconds in selectable ranges. Operating temperature range is -20 to +65 degrees Celsius. The unit is designed for 95 percent non-condensing humidity and is housed in a flame-retardant enclosure.
Applications
This module is widely used in generator protection panels, transformer differential schemes, busbar protection systems, and motor control centers. It provides critical auxiliary logic such as trip circuit supervision, lockout relay resetting, and breaker failure initiation. The BE10493002 is also applied in retrofit projects where existing relays need additional output capacity or timing functions.
Installation and Configuration
Installation involves standard panel mounting with rear terminal connections. Configuration is performed via DIP switches and potentiometers for setting time delays and selecting input/output modes. The module includes test points for verifying operation during commissioning. Periodic testing is recommended to confirm contact integrity and timing accuracy.
Reliability and Compliance
Manufactured under ISO 9001 quality processes, the BE10493002 undergoes rigorous type testing for vibration, temperature cycling, and dielectric strength. It carries CE and UL markings and is RoHS compliant. The module is designed for continuous duty with minimal maintenance.
Conclusion
Basler Electric BE10493002 offers a reliable and flexible solution for auxiliary protection logic and contact expansion. Its robust design, adjustable features, and compliance with international standards make it a valuable component for any power system protection installation.
