Cable specifications
• cable type
• Cross section of wires
• Diameter of each cable (for the cable glands
M16x1,5 of the wall-mounted version)
• pulse, sine-wave (typical sensitivity 50 mV peak-
to-peak at 250 Hz), "on/off", or standard voltage
0-5 V DC
• 0,6 Hz to 2,2 kHz, can be adjusted
• 36 V DC
depends on the position of selector "LOAD" on the
electronic board of the 8025. See chap. "7.4.10"
supplied by the transmitter depending on the position
of selector "SENSOR SUPPLY" of the 8025, either:
• 5 V DC, 30 mA max.
• (L+)-12V: supply voltage (L+) of the transmitter
minus 12 V DC (minus 12,5 V DC max.), 80 mA max.
• L+: supply voltage (L+) of the transmitter (minus
1,5 V DC max.), 140 mA max. (if the device is ener-
gized with 12-36 V DC), 80 mA max. (if the device is
energized with 115/230 V AC)
on the terminal blocks of the electronics (and through
cable glands M16x1,5, for the wall-mounted versions)
