Power consumption: max. 1.3 W
Reverse polarity protection
Overvoltage protection FEL54: overvoltage category III
Electrical connection Universal current connection with relay output
Output signal
Signal on alarm Output signal on power failure or in the event of damaged sensor: relay de-energised
Connectable load • Loads switched via 2 floating change-over contacts (DPDT)
• I~ max. 6 A (EEx d 4 A), U~ max. 253 V AC; P~ max. 1500 VA, cos ϕ = 1, P~ max. 750 VA, cos ϕ > 0.7
•I% max. 6 A (EEx d 4 A) to 30 V, I% max. 0.2 A to 125 V
• When connecting a low-voltage circuit with double isolation according to IEC 1010 the following applies:
total of voltages of relay output and power supply max. 300 V
Power supply:
Please note the different voltage ranges
for AC and DC.
Output:
When connecting an instrument with
high inductance, provide a spark arrester
to protect the relay contact.
A fine-wire fuse (depending on the
load connected) protects the relay
contact on short-circuiting.
Both relay contacts switch simultaneously.
* When jumpered, the relay
output works with NPN logic.
