Digital input/output module, 750-667/000-004, WAGO
The 75x-667/000-004 Module is equipped with four power outputs (O1 … O4) and four clock sensitive inputs (I1 … I4). The sensors can be supplied directly with 24 V, or fed by two differently clocked outputs (T1 … T2). The inputs connect potential-free, emergency-off switches with contacts, safety interlock switches, mode selectors, as well as both safety sensors and semiconductor outputs (e.g., light barriers, PLC outputs). The power outputs switch both DC13 resistive and inductive loads with up to a 2A-rated current without requiring any additional external circuit. The power outputs operate in both bipolar (high-side/low-side switching) and unipolar (common potential on one side of the load) modes. The module monitors short circuits, cross circuits and 24 V power supply from separate sources.
This configuration tool can be conveniently integrated into engineering systems supporting TCI (Tool Calling Interface) with CC2 or CC3. When exchanging modules, parameters are automatically downloaded into the control unit via PROFIsafe-compatible iPar server – depending on settings. The PROFIsafe address can be set using the DIP switch located on the side of the module, or via WAGO-I/O-CHECK. The module supports both PROFIsafe V2.4 (PROFIBUS, PROFINET) and V2.6 (PROFINET) protocols. Field and system levels are electrically isolated. Individual safety modules can be arranged in any combination when configuring the fieldbus node. If, for example, the cable length of the 24 V supply is greater than 3 m, a WAGO Filter Module or an appropriate external filter must be used for the 24 V power supply to protect the module against surge and burst (per IEC 61000-6-7 and marine applications).
