File No: 90.401 Date: december 18, 2013 Supersedes: new Date: new ipc controller 9511 air cooled chiller plant controller The Armstrong ipc 9511 is a pre-programmed controller, designed for the automation of an air cooled variable primary chiller plant. The ipc 9511 sequences the chillers and optimizes the pump operation for better efficiency of your chiller plant. The controller is fully field configurable through on-board set up screens. This plant automation solution can also be seamlessly integrated with the reporting and remote read-write capabilities of any building management system. The ipc 9511 is capable of automating a chiller plant with up to five air cooled chillers and five variable speed primary pumps in a number of configurations. The ipc 9511 offers three options for pump control: stand alone (optional with vfd and rack assembly) power supply: 100v-240v ac / 50-60 hz • Parallel sensorless for headered Design Envelope pumps • or Zone dP sensors (up to 5 zones) • or Zone temperature sensors (up to 5 zones) ipc 9511 feature matrix: model 10" hmi plc screen and web-based access screens • Single • DualArm • Twin Communication (standard) • nema 12 • nema 3r • nema 4 Serial interface or hardwired • Serial Modbus with the VFDs Serial communication protocol (optional) Modbus rtu Bacnet ms/tp Bacnet ip Lonworks Hardwired 0-10V Hardwired 4-20 mA Modbus rtu Bacnet ms/tp Bacnet ip Lonworks
