The series DGN 75AC offers a whole range of high accuracy program­mable panel meters. Each instrument is equipped on its front face with a
five 14mm high red digits display, whose brightness suits applications in
industrial control rooms perfectly.

They allow display, control and transmission of data from alternating vol­tage, alternating current and of frequencies from alternating signals.

•

DGN 75AC

frequency of an alternating signal.

• 2 programmable voltage calibers : 150V and 500V
Un = 150 VAC and 500 VAC
Overstepping 1.2 Un

• 2 programmable current calibers : 1A and 5A
In = 1.2A and 6A
Overstepping 1.2 In
Automatic caliber on 0-500V, 0-5A possible

• Voltage overload
permanent : 750 V
during 10s : 1000 V

• Current overload
permanent : 10A
during 10s : 50A

• Frequency : 45 Hz to 65 Hz

• Accuracy rating :

Wiring recommendations

The input network may carry significant disturbances, and they may disturb the complete chain. In order to avoid
this, the disturbance immunity can be made significantly better by respecting following rules :

- do not connect close to each other : the input network and the DGN 75AC power supply wires,

- do not connect close to each other : the input network and all the DGN 75AC output wires,

- use for all DGN 75AC outputs shielded cables connected to the ground on both extremities.
