Applications
- Hazardous-area NAMUR signal acquisition: Acquires signals from the hazardous area through 4 NAMUR digital inputs.
Key Features
- 4 NAMUR digital inputs: Provides 4 digital inputs and 4 NAMUR inputs for signals from the hazardous area.
- Input signal ranges: NAMUR signal 0: 0.35 mA min. to 1.2 mA max.; signal 1: 2.1 mA min. to 7 mA max.
- 24 V DC supply: Rated load voltage L+ is 24 V DC with reverse polarity protection.
- Diagnostics and indicators: Diagnostics are supported with readable diagnostic information, group error SF, digital input status, and channel fault indicators.
- Parameterizable input delay: NAMUR inputs support 0.1 / 0.5 / 3 / 15 / 20 ms, plus 0.25 ms preparation time.
- Hazardous-area isolation: Digital inputs have potential separation between channels and from the backplane bus and load voltage L+, with values dependent on hazardous-area use.
