IDEC Corporation sets the
benchmark for micro PLCs. The Micro3® combines the all-in-one
convenience of an integrated controller with the features and
flexibility of a modular PLC.
Whether the application is simple or complex, the Micro3's
additional built-ins add value, convenience, and security. A powerful
instruction set with plenty of user memory is available (over 1000
steps) in non-volatile memory. A programmable password assures safety
and security by limiting access to programs. The clock/calendar allows
real-time-based controls and event monitoring. Built-in potentiometers
can vary presets for timers, counters, registers, and high speed
counters. The Micro3 series is UL and CE approved.
controller is tiny and powerful. The smallest controller in the series
is just 4.13"W x 3.35"H x 2.36"D containing six inputs
and four outputs (ten I/O). The Micro3 can be used in
simple or complex applications up to 48 I/O.
For example, use an
AC input model for basic retrofitting. While in more demanding
applications, the Micro3 can be programmed to accept an
encoder input, control a stepper motor, and exchange data with other
Micro3s that are performing similar tasks. The Micro3's
tool kit for high-speed applications includes a high-speed scanning
mode, programmable input response times, 1 msec timing increments, and
catch inputs which detect input status regardless of scan.
unique I/O system saves money by eliminating unnecessary I/O. The
system consists of three different size modules, each with integrated
CPU, I/O, memory, and power supply. Any module can either stand alone
or connect with another module. Thus, with between ten and 48 I/O,
nine different combinations of inputs and outputs can be built. By
taking advantage of the data exchange network, up to seven modules can
be connected with each executing a unique control system.
is also capable of processing analog input and analog output. The
analog I/O modules support 0-10 VDC, 1-5 VDC, ±5 VDC, ±10 VDC and
4-20 ma. The Micro3 instruction set includes various
comparison and arithmetic functions to complement analog I/O.
designers can program the Micro3 with a program loader,
which uses a menu and fill-in-the-blank format on a four-line display.
Up to 31 programs can be stored on an optional memory card. WindLDR
(Windows based) or Cubiq (DOS based) programming software enable
designers to program the Micro3 series in ladder logic
using a PC. WindLDR or Cubiq can program, monitor, debug, and document
all Micro3 automation projects.
