ABB Measurement & Analytics Microprocessor-ControlledElectronic Unit EBS862

The EBS862 is a microprocessor-controlled electronic unit for continuous positioning of Contrac actuators, designed for rack-mounted installation with an IP20 rating. It operates from a 230 V AC single-phase supply at 47.5 to 63 Hz and supports analog control via 0/4 to 20 mA signals with HART® and RS232 digital communication. It provides three digital inputs and three potential-free relay outputs, enables torque and speed setting at 50%, 75%, and 100% of rated value, and supports FDI and DTM for device configuration. The unit weighs 40 kg, mounts vertically, and accommodates a maximum cable length of 470 m with 10 mm² conductors. Ambient operating temperature ranges from 0 to 45 °C, and it meets corrosion protection standards for C1 environments. It is rated for continuous modulation class D per EN 15714-2 and operates without derating at maximum ambient temperature.
