Overview

Description

The system’s design allows it to operate as a stand-alone control system or it may slave to an existing process control system. Basic stand-alone operation does not require software. As a slave system, the Series 2400 can operate with any existing distributed control system (DCS), programmable logic controller (PLC) or supervisory control and data acquisition system (SCADA) by way of a RS485 bus using Modbus^® protocol.

The 2400 System can be utilised in any combination of the following offshore, marine, petrochemical and industrial applications:

• Monitor toxic and flammable gas levels and generate audible/visual warnings, alarms and control outputs (such as emergency shutdown and/or ventilation control)
• Monitor flame, fire, thermal and smoke detectors, break-glass, and generate audible/visual warnings, alarms and control fire suppression outputs
• Monitor oxygen deficiency levels and generate audible/visual warnings, alarms and control outputs
• Monitor plant process functions (such as temperature, flow, level and pressure) and generate audible/visual warnings, alarms and control outputs such as process shutdowns

Features/Benefits include:

• Up to 96 Single Pole Double Throw (SPDT) relays - four per each of 24 channels - for Warning, Alarm, Fault and process-control outputs
• Up to 24 x 4-20mA isolated analogue outputs per 19-inch 24 channel card rack
• Dual redundant RS485 digital interface (Modbus® Protocol) for inputs/outputs/interface with   customer’s Distributed Control System (DCS), Programmable Logic Controller (PLC) or Supervisory Control and Data Acquisition (SCADA) System
• Uses an external supervising processor that includes Watchdog Timer and a Brown-Out detector
• An external CPU Activity monitor sets the Fault relay if no CPU activity is detected
• All peripheral cards are continually monitored for successful communications - if a fault is detected then the fault relay is set
