This module (Item No. 75x-667/000-104) features four power outputs (O1 … O4) and four pulse-sensitive inputs (I1 … I4), and can perform functionally safe logic linking of safe digital inputs and outputs. This enables the module to independently control its safe digital outputs. As a result, safe applications up to SIL 3 / PL e can be implemented without a safety controller, e.g., in combination with WAGO Controllers PFC100, PFC200, PFC300, and the WAGO Basic Controller 100. The module includes configurable virtual inputs and outputs. It can receive additional virtual output values from a controller and link this information with the safe digital inputs. The internal logic is configured using the WAGO Safety Editor (SEDI). The sensors can be powered either directly via 24 VDC or via the two pulse-timed 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 a rated current of up to 2 A, without requiring any additional external circuitry. 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. 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). 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 can operate without a safety controller and independently of the fieldbus, 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. To protect the 24 VDC power supply against surge and burst (to IEC 61000-6-7 and for marine applications), a WAGO filter module or a suitable external interference suppression filter must be used. Additional information can be found in the product manual (available in German and English). This module (Item No. 75x-667/000-104) was evaluated by UL to UL/CSA 61010-1, UL/CSA 61010-2-201, UL 121201, and CSA-C22.2 No. 213. The functional safety assessment to the specified standards was conducted by TÜV Rheinland.
