M-CONTROLLER

Multi-Channel Digital-Analog Controller

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.
