Andover Controls SCX 920 System Controller

Infinity 920 System Controller Infinity SCX 920 is a stand alone programmable microprocessor based system controller that E A T U R E S E A T U R E S E A T U R E S E A T U R E S E A T U R E S used for Direct Digital Control of chillers cooling towers boilers air handling units perimeter Stand alone DDC for System lighting etc The Infinet true peer to peer communication protocol provides the Infinity 920 with the ability to instantly communicate with Infinity network controllers such as the CX as well as the entire network of Andover Infinity controllers Up to 254 SCX 920s can be with the Infinity CX family of controllers SCX 920 comes standard with a metal cover plate suitable for panel mounting shown optional enclosure is available for wall mounting to the Infinity SCX 920 is handled via the Infinet bus a twisted pair half duplex RS 485 interface is accomplished with a token passing protocol which provides full transparent data transfer between all controllers on the network Infinity SCX 920 is capable of sensing sixteen inputs Each input can accept a digital on off counter up to 4 Hz 0 10 VDC or temperature signal Infinity SCX 920 has eight Universal outputs providing pulse variable voltage 0 20 VDC variable current 0 20mA on off control of motors and lighting with Form C relays In addition two Form C relays can be combined in software to a Tri State output for bidirectional control of motors and actuators EXPANSION SCX 920 contains an I O expansion port for the addition of low cost I O modules directly onto the bottom of the The family of modules includes the EMX 140 two pneumatic outputs the EMX 150 two analog outputs and EMX 160 eight digital inputs etc Peer to Peer Communications Transparent Data Plain English Language Programming Universal Inputs

Local Control Replaceable Battery Provides For 7 Years Accumulated Failure of RAM and Real Clock 920 920 920 System Controller 920 SCX 920 SCX 920 can be configured to meet the exact distributed control requirements of your application using Andover powerful Plain English programming language Programs can be activated within individual SCX 920s or any controller Programs are entered into an SCX 920 using an SX 8000 workstation LSX 280 Lap Top Service or network controller The program is then stored in and executed by the SCX 920 CAPABILITIES dynamic memory of the SCX 920 can be allocated for any combination of Plain English programs scheduling reporting and data logging Our object oriented language with intuitive keywords provides easy operation and In addition Plain English pre defined and customized functions and powerful math capabilities reduce time for repetitive applications DISPLAY WITH KEYPAD optional 2 x 16 character liquid crystal display provides for local viewing
