La Marche’s DC System Controller (DCSC) is an intelligent module that monitors and manages La Marche DC power systems.
DCSC provides the system with battery management, energy conservation, rectifier management, battery hibernation, battery
testing, battery charging and current limiting controls. Configuration settings and real-time parameters can be accessed locally
through the LCD or remotely using the WEB UI (Web User Interface). DCSC is equipped with a USB port, RS485/RS232 ports and
a Fast Ethernet (FE) port. The USB port allows for software upgrades and the communication ports allow the user to remotely
manage the DC power system.
Equipped with the (DCU) I/O module, the DCSC supports configurable digital inputs, alarm dry-contacts and sensor ports for
environment management and alarm reports. The alarm dry-contacts are configurable and can be easily customized, based on
requirements, through the WEB UI (Web User Interface). Equipped with the I/O module (DCU), the controller supports
configurable digital inputs, alarm dry-contacts and site sensor ports for environment management and alarms reporting. The DCU
I/O module provides the ability to add multiple sensors for: ambient temperature, humidity, water, door status, smoke and battery
temperature.

Web User Interface
The Web User Interface allows for a secure password protected remote access to the DC system for monitoring and control
purposes. The WebUI provides system’s running parameters, active alarms and configurations. Various settings can be configured
using the WebUI. Settings include: alarm parameters and configurations, rectifier management, battery management and
communications settings.
The WebUI provides flexible alarm configuration settings that includes a PLC (Programmable Logic Controller) programming
tool.
