Product information
Overview
Key Features
- 8 analog input channels: The module has 8 inputs for current measurement and 8 inputs for voltage measurement, with 16-bit maximum resolution including sign.
- Supported input ranges: Supported rated ranges include 0 to 20 mA, -20 mA to +20 mA, 4 mA to 20 mA, 1 V to 5 V, -5 V to +5 V and -10 V to +10 V.
- Oversampling performance: Oversampling is supported with up to 16 values per cycle and a minimum resolution of 62.5 μs.
- Diagnostics and alarms: The module has diagnostics, diagnostic alarms, limit value alarms, supply-voltage monitoring, wire-break detection for 1 … 5 V and 4 … 20 mA, and overflow/underflow detection.
- 24 V supply and protection: Rated supply is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection.
- Signal connections and delivery scope: It supports voltage measurement, 2-wire and 4-wire current transducers, and has encoder-supply short-circuit protection. Delivery includes the infeed element, shield bracket and shield terminal; the front connector is ordered separately.
