Micro PLCs MicroSmart

Overview

IDEC MicroSmart series PLC is the next generation of programmable logic controller. These flexible,
adaptable PLCs are as compact as they are powerful, so you can create the system you need without
increasing your space requirements or your budget.

MicroSmart CPUs are available with built-in 10, 16, and 24 I/O All-In-One units, and 20 and 40 I/O
slim style models.

Each MicroSmart CPU is designed in a compact and rugged housing. Every MicroSmart module meets
IDEC strict quality standards and complies with all major international standards; cULus, CE, TUV,
and Lloyds.

Each CPU is equipped with a standard power supply circuit, four high-speed counters, analog
potentiometer, and password protection.

The Slim type and the 24 I/O All-in-one CPU can be expanded with the many choices of expansion
modules. There are 20 modules available including four analog I/O modules, an AS-interface master
communication module, and our most recent addition to the MicroSmart family, the 8-pt AC input
module. In addition, 24V DC All-in-one CPUs are now available. Depending upon the CPU, you can
create a system with as many as 264 I/Os.

Each MicroSmart module can be enhanced with a memory cartridge for easy maintenance, a real-time
clock and calendar cartridge for real time applications, and an RS-485/RS-232 communications
adapter. These adapters allow the MicroSmart CPU to data link to the MicroSmart or other IDEC
PLCs, connect to operator interfaces, printers, barcode readers, or other RS-232 devices such as
modems for remote communication.

MicroSmart PLCs are programmable with WindLDR, IDEC's intuitive ladder logic software. The
current WindLDR version 5.03 has improved features such as a split ladder window for easy
navigation, improved tag name editor and rung comment search. Download your free demo now or
upgrade to WindLDR 5.03 if you have version 4.0 or later.
