CELDUC RELAIS
Solid-State Relays, Temperature and Power Controllers.
The advantages of solid-state relays (SSRs) over electromechanical relays (EMRs) are well known. Being fully electronic, SSRs have no moving parts; they operate silently, withstand intense vibrations without affecting performance, offer fast response times, and—most importantly—have a significantly longer lifespan.
When used under proper operating conditions, SSRs can have an almost unlimited service life. This feature eliminates the need for maintenance and reduces the risk of unexpected machine downtime, a critical factor in modern industrial operations running 24/7.
The line includes
Single-phase SSR relays
Two-phase SSR relays
Three-phase SSR relays
Four-pole SSR relays
DC (direct current) SSR relays
High-power SSR relays with integrated diagnostics
Motor control
Temperature controller, current monitoring, and communication interface in a single device
