Technical & Mechanical Data

Intrinsic Safety Barrier & Protection Architecture

The module integrates certified intrinsic safety (Ex i) barriers to restrict energy transfer to field solenoids operating in hazardous atmospheres. The 12.5 mm housing maintains high DIN-rail mounting stability under cabinet vibration. Built-in surge voltage protection limits suppress induced transients, while low internal protocol conversion latencies preserve high-speed discrete switching execution.

Field Installation & Control Wiring

Cabinet DIN-Rail Installation

• Snap the module vertically onto a 35 mm DIN mounting rail located inside an IP54 control enclosure.
• Ensure at least 50 mm clearance between blue hazardous-side field terminals and non-intrinsically safe cabinet wiring.

Terminal Wire Termination

• Wire control logic output lines to safe-side green terminals located at the module base.
• Connect field solenoid leads directly to intrinsically safe blue terminals located at the top section.

Technical Questions & Answers

• Does this module require an independent auxiliary DC power supply connection?

  No, the device operates as a loop-powered barrier deriving energy directly from the control logic input signal.

• What output voltage and current drive capability does this barrier provide?

  The unit delivers a minimum output voltage of 12 VDC at a maximum continuous load current of 45 mA.

• Can this unit be installed directly in Class I, Division 2 hazardous locations?

  Yes, the module is certified for mounting in Zone 2 / Class I, Div 2 locations inside an approved enclosure.

• What galvanic isolation test rating is maintained across the internal barrier?

  Internal transformers provide galvanic isolation rated for a 2.5 kV AC test voltage for 1 minute.

• How are input logic control states indicated on the front panel?

  A yellow LED indicator on the front faceplate illuminates when the input control signal is active.

• How should field cable shielding be terminated for this module?

  Field cable shields must be bonded to a single dedicated earth ground bar on the safe side of the panel.

• What is the channel density per unit housing on the mounting rail?

  The module packs a single high-current isolated Ex i solenoid drive channel into a 12.5 mm wide footprint.

• Are the terminal connectors removable for maintenance procedures?

  Yes, screw terminal blocks can be unlatched and removed directly without disconnecting signal wiring.
