INDUSTRIE-ELEKTRONIK Isolating Barrier D461

•••••••••••••

KEY FEATURES

■ ATEX/ lECEx certified, also approva

for UL/CSAand EAC (Russia,

Kazakhstan and Belarus Customs Union)

■ Protection grade Ex ia IIC T6/T4 Ga

■ Establishes a highly efficient system

to detect speed (and direction) in a

hazardous Ex-area, in conjunction with

one of our sensors series A5S1..

■ Provides intrinsic safety for the sensor

and its cabling

■ Comprehends sensor supply and

signal connection

■ Sensor supply monitoring

■ Free floating, therefore maximum

mmunity versus EM

■ Push / pull signal output to subsequent

monitors

D461 Front View

Safety first - for intrinsically safe (Ex ia) implementations

The BRAUN Isolating Barrier units D461 are ATEX/ lECEx certified, as well as being

approved for other international standards such as UL / CSA and EAC (Russia,

Kazakhstan and Belarus Customs Union) to meet the particular requirements of

explosion protection areas (zone 0 or 1)

The Isolating Barrier establishes a highly efficient system to detect speed and / or

direction in a hazardous Ex-area, in conjunction with one of our sensors series A5S1

to supply high level output signals to the periphery

The barrier provides an intrinsic safety circuit for the sensor and its cabling and does

not require Ex d measures

BENEFITS

■ Maintenance-free during Lifetime,

therefore minimized TCO

■ No EMI influence compared to

zener barriers

■ No signal degradation compared to

zener barriers

■ Powerful signal output to signal

evaluation

The signal input is isolated from the signal output. Both are isolated versus the power

supply. The signal output of the unit repeats the input pulse signals with push / pul

characteristics

The signal input matches the specifications of the speed sensor series A5S1..., which

are approved as intrinsic safety devices, to be installed in hazardeous area zone 0 or 1

The sensor supply circuit is monitored and a fault is signalized

The barrier unit D461 must be installed in a safe (non-hazardeous) area or within an

explosion-proof (Ex d) enclosure
