DETAILED DESCRIPTION

LRD: Lovato micro PLC

Compact devises with excellent performance, suitable for the control and supervision of low and medium complexity automatisms.
The LRD micro PLC can efficiently be used in diverse fields of industrial, service, private and residential applications, because of the variety of its functions.
Packaging machines, industrial dishwashers, lighting installations, irrigation systems, garbage disposal machinery, barrier, door and gate controls are just a few examples of where can be used.
LOVATO micro PLCs combines the facility of numerous traditional devices, such as control relays, timers, counters, hour meters and so on.
The advantages are many:

• cost reduction of materials and installation time
• space reduction
• easy reprogramming when needed
• function adjustment of the system for relay adaptation to new installation requirements.

The LRD series and expand modules (total of  44 inputs and outputs) are available for 24VDC or 24VAC or 100-240VAC power supply.
With a personal computer, two programming language logics can be used:

• FBD (Function Block Diagrams: 260 blocks)
• LADDER (contact scheme: 300 lines).

Both of these can be accomplished:
- Simulate the program directly “off-line” on a personal computer   to test if it runs correctly.
- Use the supervision mode to check the   project “on-line”.
On front, there are 8 function keys, dedicated to “on-board” programming and for status and variable supervision.
The 4 directional key can be configured as function keys programmable by the user.
