The RO-SER-CNT/IGR2-4 module is available in versions with 2 or 4 incremental encoder inputs. As interfaces the serial standards RS-232 or RS-485 are available. Additionally, the existing USB 2.0 port can be used.
- RS-232/RS-485 interface with galvanic isolation
- Open RS-232/485 protocol, plain text mode
- USB 2.0 interface with up to 480 Mbit
- 2 input counters (max. 10 MHz)
- Connection for 2/4 incremental encoder via 3 differential inputs each
- Internal 48-bit counter
- Referencing by limit position switch
- Galvanic isolation of the inputs
Incremental encoder input
With our IGR modules, the signals from incremental or rotary encoders can be evaluated. They are used to detect changes in angle or position and can thus determine the distance travelled and the direction of travel. In addition to position determination, incremental encoders can be used to measure speeds. The number of pulses per measured unit of time thus determines the absolute speed. Typically, the zero position of incremental encoders is unknown after switch-on. Therefore they must be referenced before the measurement is started.
LEDs
Each digital input and output has a separate LED that lights up when the signal state is active. Furthermore, the status of the operating voltage, the communication with the interface, error events or the occurrence of a timeout can be displayed.
Connectors
A screwless system from the manufacturer WAGO Kontakttechnik is used as the connector. The 1-wire female connectors are 100% protected against mismating and have an eject and locking mechanism. All conductor types up to 1.5mm² can be connected.
