3-CPU3 EST3 Central Processor Unit

The 3-CPU3 is the Central Processing Unit Module monitoring the status of all modules and providing the link for network communications. Although each local rail card contains their own microprocessor, the 3-CPU3 provides all inter-module communication and has the ability to download rail module operating parameters. Upon power up the 3-CPU3 automatically learns all local rail module attributes and locations. Site specific software is loaded into the 3-CPU3 which then downloads data to each local rail module. Firmware upgrades are also done from the 3-CPU3 eliminating the need to unplug chips on rail modules. Internal rail communications is accomplished in a broadcast protocol for fast response.Mounting must be in the first two local rail spaces. Options for the 3-CPU3 include the addition of an LCD display and User Interface, RS-232 Communication Card, and RS-485 Series Network Communication Cards.The 3-CPU3 is fully compatible with the 3-CPU and 3-CPU1 modules.Standard Features: 16 bit processor Up to 1,000 history events RS-485 local rail communications Multiplexed audio channels Network communication RS-485 RS-232 communication card Form ‘C' contacts for: Alarm, Supervisory and Trouble Low voltage memory write protection Non-volatile memory
