Wago 750-637/000-003 1ch Incremental encoder RS422

This module is an interface for any incremental encoder with standard connections. A counter with a quadrature decoder as well as a latch for the zero impulse can be read or enabled by the controller. The module's control can set the counter. Depending on the operating mode, the counter value is added to the latch register on a positive edge at the “C” or “Latch” input. The rate (increments/ms) is automatically acquired and can also be transmitted to the controller as an alternative to the latch value. A counter lock-out is possible using the “Gate” input. Input “Ref“ can be used to activate the initial point “C“ function. The cam outputs N1 and N2 indicate whether the counter value is within a defined range of values. The range can be adjusted. The module must be powered using an external 24 VDC power supply, from which power to the transmitter (Ui, U0) can also be derived. The shield directly connects to the DIN-rail.
