SY4S-05D
Product Description
The IDEC SY4S-05D is a 14-pin relay socket specifically designed to provide a secure and reliable connection for compatible 4-pole (4PDT) universal relays and timers from IDEC, such as the RU4S, RY4S, RY42S, RU42S, and GT5Y-4.
This socket features screw terminals for easy and secure wiring connections, ensuring a robust interface between the field wiring and the plug-in relay or timer. Its design allows for DIN rail mounting, which is standard in industrial control panels, providing flexible installation options.
The SY4S-05D is a critical component in control circuits, serving as the interface that allows relays to be easily replaced for maintenance or troubleshooting without disturbing the permanent wiring. It’s built for durability and reliability in industrial environments, contributing to the efficient operation and maintenance of automation systems.
The “D” in “SY4S-05D” likely indicates a spec
ific variant, possibly related to the terminal style or a “One Touch S” feature for front wiring, as sometimes seen in IDEC documentation.
