 ABB AO845A 3BSE045584R1 Analog Output Module The AO845/AO845A Analog Output Module for single or redundant applications has 8 unipolar analog output channels. The module performs self-diagnostic cyclically. Module diagnostics include: External Channel Error is reported (only reported on active channels) if the process power supply that supply voltage to output circuitry is too low, or the output current is less than the output set value and the output set value > 1 mA (open circuit). Internal Channel Error is reported if the output circuit can not give the right current value. In a redundant pair the module will be commanded to error state by the ModuleBus master. Module Error is reported in case of Output Transistor Error, Short Circuit, Checksum Error, Internal Power Supply Error, Status Link Error, Watchdog or Wrong OSP behavior.Detailed data: Resolution 12 bits Isolation Group to ground Under/over range -12.5% ​​/ +15% Output load 750 Ω max Error 0.1% max Temperature drift 50 ppm/°C max Rise time output filter: 23 ms disabled, 4 mA / 12.5 ms max enabled Input filter (rise time 0-90%) 23 ms (0-90%), 4 mA / 12.5 ms max Update period 10 ms Current limit Short circuit protected current limited output Maximum field cable length 600 m (656 yds) Rated insulation voltage 50 V Dielectric test voltage 500 V AC Power dissipation Typical 3.5 W Current draw +5 V module bus 125 mA max Current draw +24 V external 218 mAFrequently asked questions about the product are as follows: -What are the functions of the ABB AO845A module? The ABB AO845A is an analog output (AO) module that converts digital control signals from a process control system into analog output signals. These analog signals are typically used to control physical devices such as actuators, valves, or controllers that require continuous analog inputs such as 4-20 mA or 0-10 V. -What are the main functions of the AO845A module? It provides 8 independent output channels for applications that require multiple control signals. The module ensures that the output signals are accurate and have low drift. Each output can be individually configured as 4-20 mA or 0-10 V. It helps monitor the health and status of the module and connected equipment. The AO845A is fully compatible with ABB's 800xA process control system. -How does the AO845A integrate with the control system? The AO845A module typically communicates with the control system via Fieldbus or Modbus protocols, enabling it to seamlessly connect with other I/O modules in an ABB 800xA or S800 system.
