Product information
Overview
Key Features
- 8 analog input channels: Supports 8 channels for current and voltage measurement, with 4 channels for resistance thermometer measurement and 8 channels for thermocouple measurement.
- 16-bit resolution and accuracy: Resolution with overrange is 16 bit; operational error limit for voltage, current and resistance is 0.3% relative to the input range.
- Flexible signal ranges: Supported rated input ranges include 1 V to 5 V, -10 V to +10 V, 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA.
- Diagnostics and interrupts: Has diagnostics, diagnostic and limit value alarms, wire-break monitoring for 1 V to 5 V, 4 mA to 20 mA, TC, R and RTD, plus hardware interrupts.
- 24 V supply: Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection.
- Included components: Delivery includes an infeed element, shield bracket and shield terminal. The front connector with screw terminals or push-in must be ordered separately.
