LT Energy

Product catalog summary

Overview
LT Energy is designed for the control and command of electrical management in railway substations. It is programmable using the IEC61131-3 Straton Workbench, which is the IDE of Copalp company. The system supports DNP3.0 slave level 2 over Ethernet and serial links, Modbus RTU & Modbus/TCP, and T5 Straton protocol for distributed applications. It features embedded personal web pages, local storage events, and redundancy between two LT Energy units.

Inputs/Outputs for Safety Applications
Redundant inputs use two acquisition channels to transmit the input state and its logical complement to the CPU. They support three input voltages: 24V, 48V, and 120V. Redundant relay outputs consist of 4 I/O groups connected to electrical devices, with three voltage power options: 24V, 48V, and 120V. Each relay is driven by two serial commands with priority at relay opening.

General Specifications

Mechanical: Dimensions are customizable, with fixation options including bolted on plate or grid, or on an asymmetrical DIN rack.
Robustness: Operating temperature ranges from -40°C to +70°C, with humidity tolerance from 5% to 95% without condensation. Protection level is IP 30, with high electromagnetic interference immunity and mechanical resistance.
Power Supply: Voltage ranges from 20 to 56 Vcc with 20W power, and 120V with 20W power. Input/Earth insulation is 1,500 Veff.
Central Unit: Features an Intel PXA 270 - 300 MHz microprocessor, 32 MB SDRAM, and 16 MB FLASH memory.
Communication: Includes one Ethernet channel and multiple asynchronous links, with diagnostic LEDs for monitoring.

Inputs/Outputs Specifications

Logic Inputs: Available in blocks of 16, 32, 48, or 64 inputs, with protection against polarity inversions.
Logic Outputs: Static 24 Vcc or relay 250 Vca, with protection against overloads.
Relay Outputs: Neutral/Working contact with modularity per block.
Analog Inputs/Outputs: Various ranges with specified resolution and insulation levels.
Redundant Relay Outputs: Configurable with tri-tension voltage options.

Additional Features
Includes thresholds for logic inputs with anti-intrusion wiring control, and redundant inputs providing status and complement to the CPU. The document notes that specifications are subject to change without notice.
