Intrinsically safe applications
The fieldbus Remote Termination Panel (RTP) model TC-FFRP02 is approved as
Intrinsically Safe (IS) for use in Division 1 (Zones 0 and 1) hazardous areas. It accepts
nominal 24 Vdc input from an external power supply to provide bus power for fieldbus
devices in IS applications. This RTP provides Galvanic Isolation between the field wiring
and the RTP.
Be sure you take the reduced current limit of 80 mA into consideration when calculating
performance characteristics for the planned IS fieldbus segment.
You are responsible for adhering to all applicable national codes and local ordinances for
applying intrinsically safe equipment in a potentially explosive atmosphere.
