The IDEC Microsmart is one of the latest generation of brick size programmable logic controllers (PLC.) The C24R2 model may be expanded with up to 4 expansion modules and accessories such as, a real time clock, external communications adaptor and LCD display module. Programming is via IDECs Windows based ladder logic package, downloaded via RS232 port. For complex installations up to 32 PLCs may be networked together. Connections are made to the PLC via a plug-in screw terminal connectors. Although not shown, the entire range is available in a slim-line version (with IDC connectors) suitable for space saving applications, please enquire with sales for more information. For first time users a starter pack provides a cost effective means of purchasing a FC4A-C16R2 PLC, all required software, leads, adaptors and manual to get started.

Note:
· Accessories can be fitted to all CPUs with the exception of the C10R2
which only has one communication port and therefore cannot accept
external adaptors for external communications.
· Expansion modules can only be plugged in to the C24R2 model.
