Product Description:

The ECPSA2-0 is a motion control module produced by B & R Automation and assigned to the ECP Multi Control Modules series. The board plugs into a central processing rack and generates precision pulse trains for external drives, letting a machine controller execute coordinated point-to-point moves. By providing fast local processing and isolating the time-critical axis loops from the main PLC task, the card supports deterministic motion sequences in packaging lines, small gantries, and material-handling stations.

Each input channel on the ECPSA2-0 follows a nominal voltage of 24 VDC and uses sink logic, so the controller reads a low-side switch. Per axis, five digital inputs draw only 10 mA, minimizing sensor load and ensuring reliable recognition. For step or direction control, the pulse generator modulates frequency from 25 Hz at the slowest jog up to 20 kHz for high-speed positioning; this window lets the application span fine indexing as well as rapid traverse. When long, smooth ramps are required, the built-in profiler allows an acceleration time of up to 17 s, preventing mechanical shock and reducing power-bus current spikes.

At the other end of the ramp spectrum, acceleration can be trimmed down to 60 ms, permitting quick settle times when throughput is critical. The pulse outputs can source up to 50 mA, enough to drive optocoupler inputs on most modern servo amplifiers, and they step in increments as fine as 4 Hz for precise velocity tuning. Four transistor outputs per axis, a relay rated at 30 VDC, 1 A, and a separate 7 mA trigger line at 5 V expand the module’s ability to handle brakes, limit switches, and other auxiliaries. All signals reach the field through three 15-pin female D-sub connectors, and the hardware supports exactly two controlled axes, matching compact machines that need dual-channel coordination without a larger motion system.
