Edited by the Engineeringtalk editorial team May 18, 2007

All setup and control of the SCOM-100 is performed with a mobile phone.

SCOM-100 is a low cost, DIN rail-mounted controller unit for alarm annunciation and remote control using SMS.

The main unit incorporates a quad band (850/900/1800/1900MHz) GSM modem, two analogue inputs, four digital inputs, four power relay outputs and a serial RS-232 port.

Front panel LED indicators monitor control and digital I/O states.

The PID function makes it easy to keep temperature, level or flow to a preset value.

A variety of I/O expansion units (digital and analogue I/O) can be cascaded on the serial I/O expansion bus to meet the application requirements.

All setup and control is done using a mobile phone.

Users simply insert a SIM card with their name and phone number in the phone list and press the start up button during power up.

Simple ASCII configuration commands are used for unit setup and control.

Several commands can be packed in one SMS.

The RS-232 interface can be used to alternatively setup and test the unit using a PC or an ASCII terminal.

The rich command set features commands for configuring input alarm parameters, setup of irrigation and time scheduled programs, control functions like on/off and PID control, defining user groups and controlling system outputs with time-related parameters.
