Product Description:

The model IP3112-B318 is a 4 Channel Analog Input Fieldbus Box designed for industrial automation. It handles current signals ranging from 0/4 to 20 mA with high precision. The device digitizes inputs at a 16 bit resolution. It supports differential input connections and uses M12 screw type connectors for secure wiring.

The IP3112-B318 fieldbus box allows a maximum common mode voltage of 35 V. The measurement uncertainty is less than ± 0.3 % relative to the full scale value that ensures reliable signal integrity. Each input channel of the module features an internal 80 Ω measuring shunt. It supports differential signals with a common ground. The standard conversion time is 250 ms but can be configured down to 5 ms based on application needs. An auxiliary voltage of up to 30 V DC can be supplied through the module for sensor power. Data is transmitted electrically isolated to avoid signal interference and protect the higher level control system. Automatic detection of data transfer rates up to 12 Mbaud is supported by the box. The model is equipped with a 5 pin M12 socket and plug B-coded with an integrated T-connector for seamless network integration. The data transfer medium used is a shielded copper cable with a conductor cross section of 2 x 0.25 mm².

The IP3112-B318 fieldbus box operates at a nominal control voltage of 24 V DC with a tolerance of – 15 % to + 20 %. Electrical isolation is managed according to I/O types with no isolation between control voltage and fieldbus. The auxiliary power current depends on the I/O configuration. The IP series fieldbus box offers a rapid data transfer time of approximately 0.5 ms when using 10 stations each with 32-bit input and output signals.
