1.2 Functions and Application
The isolating barrier establishes an intrinsic safety circuit (Ex ia) feeding the sensor, and
receiving the sensor signal. The incorporated optocoupler separates this input from the
subsequent circuit. The output of the unit repeats the input pulse signals, with inverted sequence
but enforced level, to feed electronic measurements, alarms, totalizers, or controllers.
Characteristics of the input circuit immediately match the specifications of the speed sensor
series A5S1…, which are approved as intrinsic safety devices, to be installed in a hazardous
area if properly supplied.
The barrier unit D461R1…must be placed in a safe (non-hazardous) area, or within an
explosion-proof enclosure.
A speed sensor series A5S1…, in combination with the barrier D461R1…thereby establishes an
efficient speed sensing system, to supply high-level output signals to the periphery.
Version D461R1.11
The barrier D461R1.11 incorporates one signal input for single-channel sensors and one signal
output.
Version D461R1.12
The barrier D461R1.12 incorporates one signal input for single-channel sensors and two signal
outputs. Both signal outputs repeat the input pulse signal.
Version D461R1.21
The barrier D461R1.21 incorporates two signal inputs for dual-channel sensors and two signal
outputs. The signal outputs repeat one input pulse signal each.
1.3 Installation
The barrier D461R1…is designed for indoor use (NEMA 1), e.g. within switchboards, racks or
cabinets. Screw mounting or snap-on-track (DIN 50022 / 35 mm) can be used.
Protection grade IP20.
As a special version, the barrier is available in enclosure grade IP65 (NEMA4), or in explosion-
proof enclosure (Exd II C T5).
1.4 Sensor supply circuit monitoring
The sensor supply circuit is monitored against lead break and short circuit. A fault is announced
by alarm relay. An additional transistor output is non-conductive in the case of a fault. The
transistor output can be connected to the sensor supply of a subsequent module, thus enabling
its own sensor supply circuit monitor.
1.5 Circuit Isolation
Input, output and power supply are isolated from each other.
The output circuit must not be connected to other devices having an operational voltage
exceeding 375 volts (peak).

2 Hazardous protection
The safety requirements as determined by EN 1127-1, as well as the corresponding national
regulations, are to be complied with regarding primary explosion protection, i.e. measures which
prevent or restrict the formation of a hazardous explosive atmosphere.
In the case of secondary hazardous protection, i.e. measures that prevent the ignition of an
explosive atmosphere surrounding electrical equipment, the series of standards applicable to
EN 60079 and the relevant national regulations must be observed.
