Programmable logic relays
Programmable logic relays
, LOVATO Electric system of modular components, has been still more enhanced with the introduction of a programmable logic relay, compact in size yet with excellent performance, suitable for the control and supervision of low and medium complexity automatisms.
Due to the multiplicity of functions, efficiently be used in diverse fields of industrial, service and residential applications.
Packaging machines, industrial dishwashers, lighting installations, irrigation systems, garbage disposal machinery, door and gate controls are just a few examples of where can be used.

At any time and with extreme simplicity, can be set up and reprogrammed to satisfy new requirements and improve the op-eration of a system. Programming is simple and intuitive and can be done directly on the relay keypad or by personal computer, connected by LRX C00 interface and using the relative LRX SW software.

When using aPersonal Computercommon language(PC), two logics are available for programming: Function Block Diagram (FBD) and LADDER (contact scheme). Using the Simulator option, the user can control the exactness of the implemented program in off-line simulation, directly on the PC, before the on-line testing and the system set-up.

Programmingthe keypadis quite simple and straight forward, without particular programming knowledge. There are 8 function keys on the relay front, dedicated to on-board adjustment, control and supervision of digital input and output status, analog input values, time and date entry and the operation status of the relay itself. Programming sequences are shown on a backlit 4-line 12-charac-ter display.
