Specifications
In more recent years,[when?] small products called programmable logic relays (PLRs) or smart relays, have become more common and accepted. These are
similar to PLCs and are used in light industry where only a few points of I/O are needed, and low cost is desired. These small devices are typically made in a common physical size and shape by
several manufacturers, and branded by the makers of larger PLCs to fill out their low end product range. Most of these have 8 to 12 discrete inputs, 4 to 8 discrete outputs, and up to 2 analog
inputs. Most such devices include a tiny postage-stamp-sized LCD screen for viewing simplified ladder logic (only a very small portion of the program being visible at a given time) and status of I/O
points, and typically these screens are accompanied by a 4-way rocker push-button plus four more separate push-buttons, similar to the key buttons on a VCR remote control, and used to navigate and
edit the logic. Most have a small plug for connecting via RS-232 or RS-485 to a personal computer so that programmers can use simple Windows applications for programming instead of being forced to
use the tiny LCD and push-button set for this purpose. Unlike regular PLCs that are usually modular and greatly expandable, the PLRs are usually not modular or expandable, but their price can be
two orders of magnitude
