Product Description
Key Features
- Digital input configuration: 16 NAMUR digital inputs, arranged in groups of 8, with all 16 inputs simultaneously controllable.
- NAMUR encoder supply: 16 outputs with 2x 8.2 V DC encoder supply; maximum output current is 100 mA per group and 200 mA per module.
- Counting function: Up to 4 counters with a maximum of 10 kHz, or 2 counters at a maximum of 20 kHz plus 2 counters at a maximum of 10 kHz; counting width is 32 bit.
- Supply and protection: Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V, reverse polarity protection, and short-circuit protection for the encoder supply.
- Firmware and diagnostics: Firmware version V1.0.0, firmware update possible, diagnostic and hardware interrupt functions, and RUN, ERROR, PWR and channel-status LEDs.
Applications
- Digital signal acquisition: Acquires signals through 16 parameterizable NAMUR digital inputs.
- Pulse counting: Counts pulses with a maximum counting frequency of 20 kHz.
- Input diagnostics: Provides supply-voltage, encoder-power-supply, wire-break and diagnostic alarm monitoring.
