Degree of protectionIP66LoadOutput E5 (FEW52):
The load is switched via a transistor (PNP),
cycled overload and short-circuit protection, continuous 200 mA (short-circuit proof), residual voltage at transistor at Imax 2.9 V
Output WA (FEW54):
Loads are switched via 2 potential-free change-over contacts.
I~ max. 4 A, U~ max. 253 V
P~ max. 1000 VA, cos andphi; = 1, P~ max. 700 VA, cos andphi; > 0.7
I- max. 4 A to 30 V, I- max. 0.2 A to 150 V
When connecting a functional extra-low voltage circuit with double insulation in accordance with IEC 1010: The sum of the relay output and power supply voltages is max. 300 V.
output N1 (FEW58): refer to datasheet of the connected switch amplifier acc. to IEC 60947-5-6 (NAMUR)
Fail-safe modeSelecting the correct fail-safe mode ensures that the relay/the output always runs in quiescent current fail-safe.
output E5 (FEW52):
- maximum fail-safe: The output signal is < 1 mA if the switch point is exceeded (probe covered), a fault occurs or the power supply fails.
- minimum fail-safe: The output signal is < 1 mA if the switch point is undershot (probe uncovered), a fault occurs or the power supply fails.
Output WA (FEW54):
- maximum fail-safe: The relay de-energises when the switch point is exceeded (probe covered), a fault occurs or the power supply fails.
- minimum fail-safe: The relay de-energizes when the switch point is undershot (probe uncovered), a fault occurs or the power supply fails.
output N1 (FEW58):
- maximum fail-safe: The output voltage is 0 V if the switch point is exceeded (probe covered), a fault occurs or the power supply fails.
- minimum fail-safe: The output voltage is 0 V if the switch point is undershot (probe uncovered), a fault occurs or the power supply fails.

The setting on delivery is 100 kandOmega;.Proberod probes: compact instrument version 2 or 3 rods, separate instrument version 2, 3 or 5 rods
- diameter without insulation: Гevents corrosion of the probes and electrolytic destruction of the product. The material used for the tank walls is not important for measurement because the system is designed as a closed potential-free circuit between the probes and the electronics. There is absolutely no danger if the probes are touched during operation.
Input signalprobes covered - A measurable current is flowing between the probes.
probes uncovered - There is no measurable current flowing between the probes.
