3BSE023676R1 AO845 | ABB | Analog Output S800

Description

The 3BSE023676R1 AO845 is an ABB Analog Output Module for S800 I/O systems, designed for both single and redundant industrial automation applications. It features 8 unipolar analog output channels configured as single-ended unipolar outputs, with the entire 8-channel group isolated from ground for enhanced signal integrity. The module supports multiple output ranges, including 0…20 mA, 4…20 mA, 0…10 V dc, and 2…10 V dc, making it compatible with a wide range of field devices. Key technical specifications include 12-bit resolution, input impedance of 290 kOhms for voltage outputs and 230-275 kOhms for current outputs, and a range error limit of -5% to +15%. It also offers robust protection features: input shunt resistors are protected up to 30 V via PTC resistors, and analog outputs have short-circuit protection up to +24 V. Additionally, the module supports HART communication for advanced device monitoring and configuration. Temperature drift performance is optimized, with typical values of 70-100 ppm per degree Celsius for voltage outputs and 50-80 ppm per degree Celsius for current outputs, ensuring stable operation across varying environmental conditions.
