�. If the operation of this product is abnormal, especially if any unusual odor is emitted, please remove this product immediately and
contact the company.
Product description
The frequency isolation safety barrier achieves the safe
transmission of frequency signals generated by hazardous area
instruments to the safe area output. The input adopts a hysteresis
comparison circuit with high anti-interference performance, while
providing power to on-site instruments. This product requires
independent power supply, with power, input, and output isolated.

Warranty Description
�. The products have undergone strict inspection and quality
control before leaving the factory. If any abnormalities are
found or internal modules are suspected to be faulty, please
contact PARAGON in a timely manner;
�. Within five years from the date of shipment, any quality issues
that arise during normal use of the product will be repaired free
of charge by PARAGON.
�. Product damage caused by human factors or natural disasters
is not within the scope of repair.
The isolation type safety barrier and the on-site intrinsic safety
instrument are connected to form an intrinsic safety explosion-proof
circuit (intrinsic safety circuit). The system must confirm before use:
�. The explosion-proof level of on-site intrinsically safe instruments
should comply with the operating environment, and they should be
certified by a nationally authorized explosion-proof product certification
agency and have obtained an explosion-proof qualification certificate.
�. The certification parameters between the isolated safety barrier
and the on-site intrinsic safety instrument are clear and comply
with GB/T����.��, ���.�, etc.
�. If there are unclear parameters, it is necessary to form an intrinsically
safe circuit system and obtain explosion-proof products authorized by
the state confirmation from the certification body.
