Kromschroder Automatic burner control units PFU 760
The burner control units PFU 760 control, ignite and monitor gas burners for intermittent or continuous operation. As a result of their fully electronic design they react quickly to various process requirements and are therefore also suitable for frequent cycling operation.
The PFU 760 is designed specifically for directly ignited burners of unlimited capacity
in intermittent operation or in continuous
operation.
Mains voltage: 230 V AC, -15/+10%, 50/60 Hz, 115 V AC, -15/+10%, 50/60 Hz (optional), for grounded and ungrounded mains.
Length of burner cables: max. 100 m.
Max. number of operating cycles: 1,000,000.
Ambient temperature: -20 to +60°C, no condensation permitted.

Kromschroder Impulse System MPT 700
19" module for converting a controller signal to pulse cycles for gas burners. This intermittent operation circulates the atmosphere in the oven or kiln and thus achieves a uniform temperature distribution and a shorter heat-up time on all gas-fi red heattreatment ovens.
Mains voltage: 95–240 V AC, ± 10%, 50/60 Hz.
Intrinsic power consumption: 10 VA.
Additional auxiliary voltage: 12–24 V DC, ± 10%, maximum 1.1 A.
Controller inputs: 2 x 0(4)–20 mA with common ground, floating, load approx. 225 Ω.
Three-point step input: floating, 12–24 V DC, load approx. 2.7 kΩ.
Digital inputs E1–E3: with common ground, floating
