G3R-I/O
Compact SSRs for I/O Interface with High
Dielectric Strength Requirements
• High-speed models with optimum input ratings for a variety of
sensors are available.
• Input Modules and Output Modules that can be used for the
G2R are available.
• Use a coupler conforming to VDE 0884 and assuring an I/O
dielectric strength of 4,000 V.
• Incorporate an easy-to-see monitoring indicator.
• -UTU models certified by UL, CSA, and TÜV.
