Item no. 750-667/000-003

Fail-safe 4/4 channel digital input/output; 24 VDC; 2 A; PROFIsafe V2.0 iPar; yellow


The 75x-667/000-003 module is equipped with 4 power outputs (O1 .. O4) and 4 clock sensitive inputs (I1 .. I4). The sensors can be supplied directly with 24V, or fed by 2 differently clocked outputs (T1 ... T2).

The inputs connect potential-free, emergency-off switches with contacts, protection door 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 modules monitor short-circuits, cross circuits and 24V voltage supply from separate sources. Both the monitoring and additional safety relevant parameters (e.g., operating modes, switching off test pulses, discrepancy or filter times) can be configured via WAGO-I/O-CHECK.

The configuration tool can be conveniently integrated into engineering systems supporting both CC2 and CC3 tool calling interfaces (TCI).

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 on the side of the module, or via WAGO-I/O-CHECK.

The modules support both PROFIsafe V1 (PROFIBUS) and V2 (PROFIBUS, PROFINET) protocols.

Individual input modules can be arranged in any combination when configuring the fieldbus node.

To protect the module against surge voltages (over-voltage protection acc. to IEC 61000-4-5), the filter module 750-626 or an external surge filter must be used for the 24V supply voltage.

Reference the product manual for further information (available in German and English).
