ACIM-RELAY, ACI,

The M-Controller is a multi-channel controller and alarm unit. It utilizes both digital and analog 
communications to interface with a maximum of 32 remote digital  transmitter/sensors, and 8 analog transmitter/sensors.   Range and alarm setpoints are set either through the front keypad or through software that is downloaded to the controller from a PC or laptop computer.  Common relay configurations include voting, averaging, delay on actuation and deactuation, normally/not-normally energized and latching.  An additional feature includes 24 VDC transistor outputs for a horn and strobe.  A RS-422 responds as a RTU Slave using MODBUS protocol which allows the controller to provide read status 
information only.  The RS-232 interface uses a RJ-11 telephone jack. This is primarily used for uploading and downloading a large configuration database.  Also available is an analog output card that includes eight 4-20 mA analog outputs.  Each analog output can be defined in complex fashions allowing the averaging of several input signals and the assignment of different values to both the 4 and 20 mA outputs.  The M-Controller automatically linearizes the values between these two points.  

The M-Controller is covered by ACI's Two (2) Year Limited Warranty.  The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's web site, www.workaci.com
