Physical & Electrical Performance Parameters

Intrinsic Safety Barrier & Protection Features

The device incorporates certified intrinsic safety (Ex i) barriers to ensure energy-limited output execution in hazardous areas. Designed to maintain DIN-rail mounting stability under cabinet vibration, the 12.5 mm module body integrates internal clamping networks that define strict surge voltage protection limits. Direct hardwired signal conversion minimizes protocol conversion latencies during high-frequency valve pulsing operations.

Scope of Delivery

• 1 x Technical Installation Sheet

Control Cabinet Wiring & Installation Protocol

Module Mounting Procedure

• Mount the housing vertically onto a standard 35 mm DIN rail or Power Rail bus structure located inside an IP54 enclosure.
• Engage the top rear mounting tab and press the lower body firmly until the locking spring latches securely onto the rail.

Terminal Wiring Protocol

• Connect 24 VDC auxiliary power and logic control signals to the safe-side green terminals at the bottom of the module.
• Route hazardous area field solenoid lines strictly through the intrinsically safe blue terminals located at the top section.

Technical Questions & Answers

• What is the continuous current drive capacity supplied to the hazardous area solenoid?

  The output stage delivers a continuous current up to 60 mA at a minimum drive potential of 10 VDC to the field load.

• How does the internal line fault detection mechanism operate?

  The module continuously monitors field wiring loops for open-circuit or short-circuit faults and reports status via an LED.

• Can this solenoid driver be powered through a Power Rail bus?

  Yes, the module includes power contacts on its base that connect directly to a 35 mm DIN Power Rail distribution bar.

• What physical separation must be maintained between safe and hazardous wiring?

  A minimum clearance space of 50 mm must be maintained between blue intrinsic safety terminals and non-Ex wiring.

• What galvanic isolation test rating applies to this hardware barrier?

  The internal galvanic isolation withstands a 2.5 kV AC test voltage for 1 minute between safe and hazardous circuits.

• How are field wiring errors signaled to the master controller?

  Line fault states trigger a fault output contact or Power Rail error bus signal to alert the upstream system.

• Is hot-swapping supported for this module inside a control panel?

  Yes, terminal blocks can be unplugged while energized, provided the surrounding atmosphere is free of explosive gas.

• What conductor size is recommended for field screw terminal connections?

  Terminal blocks accept solid or stranded copper conductors ranging from 0.2 mm2 to 2.5 mm2 (24 AWG to 14 AWG).
