Apollo XP95 I.S. Protocol Translator - Dual Channel [SIL2] (55000-856APO)

The Apollo XP95 Intrinsically Safe (I.S.) Protocol Translator is installed in the safe area ensuring the integrity of communication between control equipment and field devices and safety within the limits of BASEEFA approvals.

Operation

The translator is a loop-powered device which draws a low quiescent current and is therefore transparent to both the loop driver and the I.S. detectors. Since the translator is used within the safe area, i.e., before the safety barrier, no I.S. certification is necessary. The translator falls within the generic description ‘Safe Area Apparatus’.

The translator is housed in a moulded plastic enclosure which can be either clipped onto a standard 35 mm DIN-Rail (DIN 46277) or panel mounted by using pull-out latches in the base. The translator is available in single-channel or dual-channel versions. Each channel should only be connected to a single intrinsically safe circuit through an appropriate safety barrier.
