Product Description:

The X67AI1323 is an analog input module produced by B&R Automation for the X67 Analog Input Output Modules series. Designed for decentralized machine architectures, the unit brings four-channel current measurement directly onto IP67 field wiring so that cabinet space is not required. By digitizing process signals close to sensors, it reduces noise pickup and supports cleaner signal transfer in conveyor, packaging, and processing equipment. In a typical installation, the module mounts on a machine frame, communicates over the X2X real-time bus, and forwards converted data to the central PLC. This layout is useful where remote sensing points are spread across a machine and long analog cable runs would otherwise add complexity or increase susceptibility to interference.

The module presents 4 analog inputs, and each channel accepts 0 to ±30 mA process signals while tolerating a common-mode potential up to ±11 V. A successive-approximation converter finishes a complete update every 400 µs, which supports rapid response when measured values change during active machine operation. Quantization is provided at 12-bit resolution, yielding 4096 discrete steps for scaling under IEC 61131 runtime libraries. An internal low-pass filter with a corner frequency of 1 kHz suppresses higher-frequency noise so dynamic but non-oscillatory signals can be passed to the controller with stable behavior. This combination suits process signals that need dependable current measurement without adding excessive delay to the control loop.

Beyond bandwidth management, the filter rolls off at 40 dB per decade, which helps reduce aliasing from fast switching devices located near sensor wiring. Channel isolation is verified for 500 Veff, so field-side circuits and bus electronics remain electrically separated during faults or transient disturbances. Gain deviation is limited to 0.1%, supporting calibrated measurement chains with minimal correction in application code. System power is drawn from a single 24 VDC supply, from which the module feeds its X2X interface, internal electronics, and transmitter excitation. The compact housing also fits well on distributed machine sections where available mounting space is limited and direct access to sensor connections is preferred.
