Product Description:

The model X20AI4636 is an Analog Input Module offering high precision data acquisition. It features four differential inputs with a 16 bit digital converter resolution. The module supports both voltage and current signal measurements through different terminal connections.

The X20AI4636 analog input module from B & R Automation supports voltage input ranges up to ± 10 V and current inputs from 0 to 20 mA. It provides a digital converter resolution of ± 15 bit for voltage and 15 bit for current inputs. The conversion time of the model is 40 microseconds for all inputs that allows fast signal processing. Output format is in integer (INT) type where voltage output ranges from INT 0x8001 to 0x7FFF with a resolution of 305.176 µV per LSB. Current output ranges from INT 0x0000 to 0x7FFF with a resolution of 610.352 nA per LSB. Input impedance for voltage signals is rated at 20 MΩ. This ensures high accuracy with minimal signal interference. The module includes protection against wiring errors involving supply voltage. Permissible input signal levels are ± 30 V for voltage and ± 50 mA for current. Diagnostics features of the module include monitoring of module run/error status, input status and channel type using LED indicators and software tools. Power consumption is rated at 0.01 W for the bus and 1.5 W for internal I/O.

The X20AI4636 analog input module from the X20 Fieldbus series exhibits a maximum error of 0.08 % for gain in both voltage and current inputs with offset errors at 0.01 % for voltage and 0.02 % for current. Gain drift is limited to 0.01 % per degree Celsius for both input types. The model supports oversampling function up to 16 analog values per channel.
