Applications
- Current measurement: The module supports current measurement as a 2-wire transducer and analog value generation for the inputs.
Key Features
- 2 analog current inputs: The module has 2 analog inputs supporting -20 mA to +20 mA and 4 mA to 20 mA, with 50 Ohm input resistance.
- 14-bit resolution: Resolution with overrange is max. 14 bit; ±20 mA provides 14 bit and 4 to 20 mA provides 13 bit.
- Current measurement timing: Integration time is 16,7 / 20 ms, and conversion time per channel is 65 ms; 55 / 65 ms.
- Signal diagnostics: Wire-break diagnosis is available for the 4 to 20 mA measuring range only. Group error and overflow/underflow diagnostics are also available.
- 24 V supply and isolation: Rated load voltage L+ is 24 V DC from the power module. The analog inputs are isolated from the backplane bus, but not between channels or from L+.
- SIPLUS environmental design: The module has conformal coating and a collected temperature range of -25…+60 °C.
