Matsushita Electric Works has several new relay blocks with either electromechanical or solid-state relays.
Matsushita Electric Works has several new relay blocks with either electromechanical or solid-state relays.
The relay blocks benefit panel builders by reducing the amount of wiring and wiring mistakes, as well as also being easy to test and troubleshoot.
Panel builders often use banks of single relays that are wired individually to the same common and live terminals.
By using a bank of relays already built into a block, much of the awkward and time-consuming wiring is reduced, hence the introduction of the relay blocks.
The relay blocks are available with plug-in terminals for both input/output and with an FK connector for the Input terminal allowing quick connection to the most popular PLCs.
The FK connector can easily be joined to a single ribbon cable with relevant connectors.
The relay block modules are available in the most popular 4/4, 8/8, 16/16 combinations and allow excellent space saving with the added benefit of LEDs to show the user which relays have been activated.
The electromechanical relay blocks require a control signal of 12-24V DC and have a nominal rated current/voltage on contacts of 10A/250V.
There is no minimal mounting distance between modules, allowing multiple units to be used together.
