USB-/Ethernet Stepper Motor Module with 8 Relay Outputs and 8 Opto Inputs (24V / with Counters)
The proven USB-/ETH-based stepper motor module is now additionally available with 8 digital inputs and 8 outputs. The 8 outputs are implemented via relay contacts, while the 8 digital inputs each feature a 16-bit counter (maximum sampling rate: 10 kHz).
The stepper motor module from DEDITEC is designed for bipolar two-phase stepper motors. Microstepping can be set to a resolution of 1/16 step, ensuring smooth operation and highly accurate positioning. Since many customers requested additional I/O capabilities, DEDITEC now offers a complete module featuring 2 stepper channels, 8 opto-isolated inputs, and 8 relay outputs.
Each of the 8 input channels includes a 16-bit counter with a sampling rate of up to 10 kHz, enabling fast event counting, such as rotational speeds, light barriers, turnstiles, or push-button inputs. Basic logical operations can also be implemented, e.g., automatically switching outputs once a defined threshold value is reached.
Software
The extensive Windows driver library (DELIB) provides a unified and easy way to control the module across almost all common programming environments. The user-friendly graphical interface enables rapid configuration of all stepper motor characteristics. Available options include: position control, velocity control, start and stop frequency, max. step rate, acceleration and deceleration ramps, reference and position switches, and much more.
Up to four stepper motor modules can soon be linked together, enabling control of up to eight virtual axes.The module’s internal temperature can also be monitored.
Communication between module and PC is carried out, for example, via a galvanically isolated USB interface, which also supports distances over 100 meters. Electrical noise caused by motor activity does not interfere with USB data transmission.
