4.1 Supply voltage
The supply voltage is with version -24E in the range of 18 to 30 VDC and with version –E12 within 10
to 18 VDC. The presence of the supply/ internal operating voltage is indicated by the 2 green LEDs on
the pcb.
To protect the electronics an (to the supply voltage version corresponding) internal self-healing
“polyswitch-resettable®” fuse is built in. Whether an external additional fuse is necessary is to be
considered. However, an additional external fuse of
SI
extern
0,4 A slow is recommended.

4.2 Galvanic isolation
The supply voltage of the amplifier is galvanically isolated from analogue output, sensor supply and
sensor signal. To unset this isolation, just bridge clamp 2 and 4 (resp. 6).

4.3 Analogue Outputs
According to your order the following analogue outputs are available:
…-010-… Analogue output: 0…10 V Zero-point at 5 V
…-B10-… Analogue output: ±10 V Zero-point at 0 V
…-020-… Analogue output: 0…20 mA Zero-point at 10 mA
…-420-… Analogue output: 4…20 mA Zero-point at 12 mA
