Programmable Logic Relays
What is a logic relay?
A logic relay is a programmable relay with a number of inputs (typically 8) and a number of contact outputs (typically 4).
What do programmable relays do?
The internal components of a programmable relay can be linked together using software, to make an operational circuit to achieve the functionality that would normally be achieved by using a number of discrete components such as counters, timers and relays.
Why Use a Logic Relay?
The advantages of a programmable relay over discrete relay logic are:
Where can you use Logic Relays?
Logic relays can and are used in many different applications in the industrial sector where the logic complexity is to small for a larger PLC, in commercial applications for simple levels of control, in agricultural applications for irrigation control and even in domestic applications for heating control, garage door control, gate control and home automation.
Programming Logic Relays
Programming is easily achieved using the G-soft NX software which uses a graphical interface to enable ladder logic programming.
