Features
Supply and switching units NxxU are used for energizing of NAMUR output sensors (DLS–27Xi, CPS–24Xi etc.) located in hazardous explosive areas. Due to state of connected sensor they switch their output changeover relay contact or transistor switch. Moreover they can provide simple 2-state level regulation (pump-up and pump-down control).
Classifi cation of explosive-proof performance:
II (1)G [Ex ia] IIC
I (M1) [Ex ia] I
● For energizing and state-detection of NAMUR sensors (EN 60947-5-6)
● Connected sensor can be located in hazardous explosive areas up to zone 0 • Relay or transistors output
● High frequency switching (up to 2kHz – ver. "T")
● LED state indication
● Power supply 230 V AC or 24 V DC
● Mounting on DIN rail 35 mm
