Power Supply
Supply voltage for use in zones 0 and 1: see approvals from chapter 2.3.
The sensors of the A5S1... series may only be operated in hazardous area zone 0 or 1 if they
are supplied by an associated electrical equipment approved for Zone 0 / category 1. The signal
wire must also be connected to an intrinsically safe circuit.
This requirement is best met with the BRAUN Isolating Barrier D461... series. These isolating
barriers also provide the necessary supply voltage required for signal transmission over greater
distances or under another load. The output of the isolating barriers is again a pulse signal with
a strong level. This results in a powerful system for speed detection in the hazardous area and
signal transmission to any measurement device.
The isolating barrier must be installed in a safe (non-hazardous) area.
4.3
Signal Output
Rectangular pulses with constant high level and low level over the entire speed range
.
Push-Pull amplified output. Maximum load 20 mA.
The signal output is short circuit proof and protected against polarity error.
4.4
Speed (Frequency-) Range
Speeds with a maximum signal frequency of:
A5S1DS:
0 Hz…12 kHz
A5S1DD:
0 Hz…25 kHz
