Wago 750-637 fieldbus module

Incremental encoder interface; RS-422; 32 bits This module is an interface for incremental encoders with standard connections (e.g., RS-422, differential, single-ended). A counter with quadrature decoder as well as a latch for the zero impulse can be read or enabled by the control. The control can set the counter or transmit the counter value to the Latch. As an alternative this can also be done using input “C” or “Latch.” The rate (increments/ms) is automatically acquired and can also be transmitted to the control 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 (Ue, U0) can also be derived. The shield (screen) is directly connected to the DIN-rail.
