Product Description:
The ECI164-0 is an AC input module manufactured by B&R Automation for the ECZ Multi Analog Modules series. Designed for discrete signal acquisition in machine-control racks, the unit converts line-level voltages from field devices into logic states for the controller. By housing sixteen optically isolated channels in a single slot, the module saves space and wiring while maintaining safety. In automated assembly lines or process skids, the ECI164-0 forms the interface between field sensors and the CPU.
The module provides 16 discrete input channels, organized into 4 independent groups so each cluster can share a common return while remaining galvanically separated from the others. Each channel accepts a 120 VAC nominal signal and recognizes a logic-true state once the line exceeds the 102 VAC minimum. Overvoltage tolerance extends to 144 VAC, allowing headroom for mains fluctuations. Internal timing circuits impose a switch-on delay of less than 25 ms and the same limit for switch-off, preventing contact bounce from propagating to the processor. These parameters help the module capture state changes reliably within fast machine cycles.
Within each channel, the Schmitt trigger sets the switching points so logic becomes active at 85 VAC and inactive below 55 VAC, ensuring clear hysteresis around the mains zero crossing. Surge protection clamps transients up to 1500 V for 10 µs, safeguarding downstream circuits. Despite the high-energy rating, the board draws only 0.5 W from the +8 V backplane supply, minimizing thermal load in dense cabinets. Input status is transferred at Program End (EOP), aligning data refresh with deterministic cycle boundaries, and LED indicators show every channel state locally. The card fits MULTI, MIDI, and M264 racks, letting designers mix it with digital, motion, or CPU slices in the same enclosure.
