Product Description:
B&R Automation manufactures the 3IP161 as part of its System 2005 Controllers series. The module combines analog, digital, and CAN communication resources in one unit. This arrangement allows a single controller slot to gather process data, drive actuators, and relay information to higher-level systems in distributed industrial automation. It can handle measurement signals, command outputs, and bus communication within the same hardware platform, which helps consolidate control functions in compact machine designs.
The analog section is arranged around six differential input channels and six voltage outputs. Each input is digitized within ≤100 µs, allowing the CPU to react quickly to changing signal levels during cyclic control. Measurement accuracy is supported by a full-scale range of ±10 V and a 14-bit converter, supplying 16,384 discrete codes for process variables. The outputs use the same voltage span and employ a 12-bit digital-to-analog converter for setpoint generation, giving 4,096 steps of resolution. Drive signals for valves or transducers are provided on 6 analog outputs, and program code, calibration tables, and runtime parameters that govern these analog transactions are stored in 850 kB of SRAM for fast access during control tasks.
The digital domain offers up to 12 inputs that accept 24 VDC logic levels and 12 transistor outputs that switch the same voltage at loads not exceeding 0.1 A. All channels share a galvanically isolated CAN interface, so field wiring faults cannot propagate into the controller electronics, and this link supports network speeds up to 500 kBit/s for synchronized node updates. Nonvolatile storage is supplied by 1.5 MB of FlashPROM, which retains configuration data during power cycles. The fixed I/O mix suits stations that need both direct field connections and CAN-based device exchange in the same control layer.
