供应电子插件FEM54 FEM54 

电子插件EM54 electronic insert

(AC/DC with relay output)

Power supply

Alternating voltage 19 V…253 V, 50/60 Hz or DC voltage: 19 V…55 V

Power consumption: max. 1.5 W

Reverse polarity protection

Separation voltage: 3.7 kV

FEM54 overvoltage protection: overvoltage category III

Electrical connection

Universal current connection with relay output (DPDT)

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.

** See below "Connectable load"

Signal on alarm

Output signal on power failure or in the event of device failure: relay de-energised
