Key Features
- Counter module and channels: FM 350-2 counter module with 8 counter inputs and 8 digital inputs.
- Counting frequency: Maximum counting frequency is 20 kHz; with an incremental encoder, it is 10 kHz.
- Encoder support: Supports asymmetrical incremental encoders, 24 V initiators, 24 V directional elements, NAMUR encoders to DIN 19 234, and 2-wire sensors.
- Supply and inputs: Rated auxiliary and load voltage is 24 V DC, with a permissible range from 20.4 V to 28.8 V. Input signals are -3 to +5 V for signal "0" and 11 to 30.2 V for signal "1".
- Diagnostics and isolation: Provides readable diagnostic information, parameterizable diagnostic alarms and hardware interrupts, a red Group error SF LED, and potential separation between channels and the backplane bus.
- Connection and dimensions: Requires 1x 40-pin front connector. Dimensions are 80 mm wide, 125 mm high, and 120 mm deep; approximate weight is 460 g.
