SAFETY, EX, AND GL:

All-in-One Module

The Europe Commission’s functional (EN IEC 62061) and control (EN ISO 13849) safety standards, and, in particular, the Machinery Directive have increased the safety demands placed on marine systems and applications. These requirements apply equally to software components. All related marine equipment, such as access points, bulkhead or tailboard controls, as well as conveying machinery, cranes, and dredging vessels must comply with these increased standards. This is particularly the case for offshore drilling and extraction platforms, where the most stringent requirements are placed on protecting people, equipment, and the environment. For example, danger to persons must be eliminated in the hazardous area of hydraulic pipe handling arms.

Safe and GL-Certified

Vibration, shock loads, fluctuating temperatures, supply voltage variations, and electromagnetic interference are among the major challenges faced in shipbuilding and on/offshore applications. Safety modules in the WAGO-I/O-SYSTEM 750 Series are certified by the Germanischer Lloyd (GL) classification society for marine applications. They meet the requirements for both functional safety (SIL, Safety Integrity Level) and explosion protection (ATEx, IECEx). With a width of just 24 mm, the modules are also extremely compact and robust. Furthermore, their DIN-rail-mounted design permits easy, tool-free handling. One of the system’s highlights is its ability to safely and economically create mixed nodes by combining safety modules with the more than 400 digital, analog and specialty, non-safetyrelated I/O modules to expand application functionality.

WAGO's Safety Modules include:

• The 750-667 Digital I/O Module with four inputs and four flexibly configurable 2 A outputs. A key feature is the 1:1 relationship for a reliable allocation of the feedback signals per input.
• The 750-666 10 A Module, which features four inputs and two power outputs, can also be used separately. This module simultaneously disconnects the power supply for a whole group of outputs (safety switching device), so that all downstream, switchconnected actuators are deactivated.
• The 750-663 F-EX Module, which is a digital input module for sensors in Ex Zones 0/20 and 1/21, is ideal for offshore applications.

The WAGO-I/O-SYSTEM 750 PROFIsafe modules comply with IEC 61508, SIL 3, and can be used in safety applications up to categories 4 and PLe (EN ISO 13849) or SIL 3 (EN IEC 62061).
