Product Description:

The 3AO360.60-1 analog output module is produced by B & R Automation for use in the System 2005 Controllers series. It provides eight programmable voltage channels that translate digital setpoints from the CPU into standardized control voltages for drives, proportional valves, or instrumentation within an automation cell. By sitting on the local backplane, the unit extends the controller’s capability to issue continuous signals instead of simple on/off commands, which is useful when closed-loop positioning or process regulation is required.

Each channel delivers a full swing of -10 V to +10 V with a fine 305 µV step size produced by a 16-bit converter, and this resolution supplies 65,536 discrete values so voltage trimming errors stay below normal process tolerances. The conversion cycle completes in 192 µs, enabling rapid refresh for motion or vibration control tasks. Basic linearity is held to ±0.011% at 24 °C. A built-in first-order 8 kHz low-pass filter suppresses high-frequency noise, while continuous short-circuit protection and output-to-PLC isolation help prevent fault propagation to upstream electronics. An internal enable relay controls the switch-on and switch-off behavior.

The module offers 8 voltage outputs, and each one is designed for loads down to 1 kΩ while remaining capable of sourcing or sinking up to ±10 mA without exceeding its operating range. A default 10 kΩ impedance between the positive and negative terminals is present before the CPU starts cyclic updates. Thermal stability across the plant floor is aided by a gain drift of ±25 ppm/°C and an offset drift of ±100 µV/°C, so signal accuracy is largely preserved from 0 °C to 60 °C. Total module demand on the backplane is only 5.1 W, allowing dense I/O racks without overloading the power supply.
