Product Description:

The 3IP151.60-2 controller module is produced by B&R Automation as part of the System 2005 Controllers series. Designed for slot mounting beside the CPU, it combines mixed-signal conditioning, on-board buffering, and field wiring terminals into a single package. The unit provides the analog and digital interface capacity required to link sensors, actuators, and motion drives directly to the backplane bus, streamlining machine automation where compact I/O density and local real-time processing are needed. By placing these functions in one module, the system can reduce external signal-conditioning hardware and keep cabinet layouts more compact.

It accepts an analog input span of ±10 V, digitized through a 14-bit converter across 6 independent input channels, giving 16,384 numerical steps for each measured variable. The output section supplies setpoints over the same ±10 V window through a 12-bit DAC that feeds six voltage drivers, enabling closed-loop regulation of valves, servo references, or inverter commands. Two dedicated reference lines provide full differential swing at +10 V / -10 V, making them suitable for servo amplifiers that require symmetrical signals. Channel-to-channel isolation and automatic calibration reduce offset drift when ambient temperatures change, which helps preserve stable signal quality during long operating cycles.

For discrete control tasks, the board supports up to 12 digital inputs and 12 digital outputs, all referenced to the field rail of 24 VDC. Each output can source or sink up to 0.1 A, allowing direct actuation of interface relays, indicator lamps, or small pneumatic solenoids. Communication to supervisory equipment is handled through one CAN node and one RS-232 port, so the module can exchange status data with both networked controllers and serial devices. Data is stored in 512 kB of FlashPROM, and an additional 850 kB of SRAM buffers variables and high-speed acquisition blocks. The module also includes 2 bipolar output drivers that are electrically isolated from the standard analog group to help maintain signal integrity when feeding differential loads.
