8 .11 Impulse system MPT 700

With 11 outputs for activation of burner control units
PFU 780. The furnace atmosphere is circulated thanks
to intermittent operation, and thereby constant tem-
perature distribution and shorter heating-up periods for
all gas-fired heat treatment furnaces are ensured.
Mains voltage: 95–240 V AC, ± 10%, 50/60 Hz.
Power consumption: 10 VA.
Additional auxiliary voltage:
12–24 V DC, ± 10%, max. 1.1 A.
Controller inputs: 2 x 0(4)–20 mA with common earth,
floating, load impedance approx. 225 Ω.
Three-point step input: floating, 12–24 V DC, load im-
pedance approx. 2.7 kΩ.
Digital inputs E1–E3: with common earth, floating,
12–24 V DC, load impedance approx. 2.7 kΩ.
Order No. 84395050
