WAGO 750-616 Distance Module for Ex i Applications

Key Features and Product Highlights

• Ex i Distance Maintenance: Provides critical spacing to meet stringent clearance and creepage distance requirements for intrinsically safe (Ex i) applications in hazardous areas .

• Required for Hazardous Area Compliance: When building a node with Ex i I/O modules, four 750-616 distance modules must be installed after each Ex i section to maintain proper isolation .

• Passive Module Design: Contains no electronic components; simply passes through system voltage (5 VDC) via data contacts to maintain bus communication .

• Compact Form Factor: 12mm width for space-efficient DIN-35 rail mounting, matching the footprint of standard 750 Series I/O modules .

• Industrial Construction: Light gray housing (standard version) with polycarbonate/polyamide 6.6 materials, IP20 protection rating .

Critical Application Requirements

When using Ex i I/O modules in a hazardous area node:

1. Ex i Supply Module Required: Only Ex i bus supply modules (750-606, 750-625/000-001) may power sections with Ex i I/O modules .

2. Four Distance Modules: After each node section containing Ex i I/O modules, four 750-616 distance modules must be installed .

3. Exceptions:

   • If followed by an end module for bus extension (750-627), one distance module is sufficient .

   • If followed by a standard end module (750-600), no distance modules are required .
     

     

Applications

• Hazardous Area Installations: Building intrinsically safe (Ex i) I/O nodes for Zone 0/1/20/21 applications.

• Chemical & Petrochemical Plants: Maintaining isolation requirements for instrumentation in explosive atmospheres.

• Pharmaceutical Manufacturing: Ex i signal acquisition in hazardous production environments.

• Oil & Gas Facilities: Intrinsically safe I/O for offshore platforms and refineries.

• Process Automation: Compliant signal interfacing for hazardous area sensors and actuators.

Why Choose the WAGO 750-616?

• Regulatory Compliance: Ensures Ex i installations meet international hazardous area standards for clearance and creepage distances .

• System Reliability: Proper spacing prevents electrical breakdown and maintains intrinsic safety integrity.

• Seamless Integration: Same footprint and mounting as standard 750 Series modules, simplifying panel design.

• Proven Quality: Manufactured by WAGO, a global leader in electrical interconnect and automation technology.

• Variant Flexibility: Choose standard or XTR extended temperature versions based on application requirements.
