Product Description:
The 8I44S200018.000-1 module is manufactured by B&R Automation for the 8I4 ACOPOS Inverters series. It installs on the inverter backplane to provide mixed analog and digital signal handling, so the drive can exchange process data with external sensors, field devices, and higher-level controllers. In typical machine automation cells, the card bridges low-level transducer outputs to the inverter’s DSP, enabling coordinated speed or torque regulation without a separate remote I/O rack. Its physical footprint and wiring pattern follow the series layout, allowing consistent cabinet arrangements across different power ratings.
It supplies a continuous DC link for auxiliary sensors through a 24 V rail that can deliver 100 mA, and a separate 5 V rail rated at 10 mA for low-power logic encoders. The inverter communicates with upstream controllers over the RS485 physical layer while data framing follows the Modbus RTU protocol, ensuring deterministic polling on multidrop machine networks. The connected drive section is rated at 0.18 kW, making the card suitable for small pumps, feeders, or positioning tables. One analog channel can be configured for current or voltage measurement, and four digital inputs accept 24 V signals for start, stop, or limit detection, while a single digital output can forward drive status to a relay.
Signal granularity on the analog side is governed by a 10-bit converter, giving 1024 discrete values across the selected range. When the voltage-mode input is selected, the card presents a high resistance of 30 kΩ, minimizing loading on sensitive sensor circuits. The current-mode path instead terminates into 250 Ω, establishing a standard 4–20 mA loop burden. For edge-triggered commands, the digital input stage uses a pull-up network of 3.5 kΩ, shaping current flow when sensors switch. These electrical characteristics allow analog transducers and proximity switches to share the same backplane while maintaining stable signal handling and response time.
