Safe digital input/output, 4/4 channels, DC 24 V, 2A, PROFIsafe
The 75x-667/000-004 module has 4 power outputs (O1 . O4) and 4 clock-sensitive inputs (I1 . I4). The sensors can be fed directly with 24 V or through the 2 differently clocked outputs (T1 . T2). Potential-free, contact-based emergency stop buttons, safety door or operating mode selector switches as well as safe sensors or safe semiconductor outputs (e.g. light barriers, PLC outputs) can be connected to the inputs. The power outputs switch resistive and inductive loads according to DC 13 with a nominal current of up to 2 A without additional external circuitry.
The power outputs can be operated bipolarly (high-side/low-side circuit) or unipolarly (common potential on one side of the load).
Short circuits, cross circuits and 24V external feed are monitored. Monitoring and other safety-relevant parameters such as operating modes or switching off the test pulses, discrepancy times or filter times can be parameterized via WAGO-I/O-CHECK.
The parameterization tool can be easily integrated into engineering systems that support the TCI (Tool Calling Interface) with CC2 or CC3.
Depending on the setting, the parameters are automatically downloaded to the controller via a PROFIsafe-compliant iPar server when the module is replaced. The PROFIsafe address is set on the coding switch on the side or alternatively via WAGO-I/O-CHECK.
The module supports the PROFIsafe protocols V2.4 (PROFIBUS, PROFINET) and V2.6 (PROFINET).
The field and system levels are galvanically isolated from each other.
The arrangement of the individual safe modules is arbitrary during configuration in the fieldbus node.
If necessary (e.g. cable length of the 24V supply greater than 3 m), a WAGO filter module or a suitable external filter must be used for the 24V supply to protect against surge and burst (according to IEC 61000-6-7 and the shipping sector).
