25D Series

PRODUCT DESCRIPTIONS

The 25D Series is a small high insulation resistance relay, which

comes in 1 Form A and 2 Form A configurations. The insulation

resistance rated 10 is top of its class, and ensures to reduce

mounting area. These features make this series ideal for DC

measurement and DC parametric tests.
