GE Fanuc UR8NH – Universal Relay Module with 8 Poles, Normal Configuration, High Current

In stock

Product Introduction:
The UR8NH is the standard universal relay module in the GE Fanuc 8-pole relay family. The “UR” indicates Universal Relay, “8” specifies eight relay poles, “N” denotes Normal (standard) configuration, and “H” indicates High Current. This is the workhorse relay module for general-purpose industrial applications. It provides eight independent form A (normally open) relay outputs with a common return terminal, each capable of switching 10 Amps at 250V AC. The normal configuration offers a balanced combination of speed, power consumption, and contact life, making it suitable for the vast majority of discrete control applications. It is the default choice when no special features (fast, low-power, or high-hold) are required.
