Fail-safe 4/4 channel digital input/output; 24 VDC; 2 A; Logic; PROFIsafe

<p>This module (Item No. 75x-667/000-104) features four power outputs (O1 … O4) and four clock-sensitive inputs (I1 … I4), enabling a functionally safe connection between fail-safe digital inputs and outputs. As a result, the module can autonomously control its safe digital outputs, enabling the implementation of safety applications up to SIL 3 / PL e without the need for a dedicated safety controller.</p><p> </p><p>The module has 30 virtual inputs and 30 virtual outputs, making it possible to receive additional virtual output values from a controller and to link this information to the fail-safe digital inputs. The internal logic is configured using the WAGO Safety Editor (SEDI).</p><p> </p><p>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.</p><p> </p><p>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. Monitoring and other safety-relevant parameters—such as operating modes, test pulse deactivation, discrepancy times, and filter times—can be configured using WAGO-I/O-CHECK.</p><p> </p><p>The configuration tool can be conveniently integrated into engineering systems supporting both CC2 and CC3 tool calling interfaces (TCI). The PROFIsafe address can be set using the DIP switch located on the side of the module, or via WAGO-I/O-CHECK.</p><p> </p><p>The module can be operated without a secure controller and is fieldbus-independent, but also supports the PROFIsafe protocol V2.6 (PROFINET®). Field and system levels are electrically isolated. Individual safety modules can be arranged in any combination when configuring the fieldbus node.</p><p> </p><p>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). Additional information can be found in the product manual (available in German and English). This module (Item No. 75x-667/000-104) has been evaluated by UL in accordance with UL/CSA 61010-1, UL/CSA 61010-2-201, and UL 121201, CSA-C22.2 No. 213 standards.</p><p> </p><p>The functional safety evaluation was performed by TÜV Rheinland in compliance with the specified standards.</p>
