Applications
Click on images for close-up view.
 |
Boilers The DG..VCT controls the minimum or maximum gas inlet pressure on high-performance boilers. |
 |
Low-pressure cut-off and high gas pressure protection device If the pressure is either too high or too low, the double pressure switch DG../..C switches, in order to avoid start-up or to initiate a safety shut-down. |
 |
Fan monitoring On forced draught burners, the minimum or maximum pressure is retrieved by the burner control unit via the pressure switch DG..VCT. If the set switching point is exceeded or undershot, the fan will either be switched on or off by the burner control unit. |
Specifications
| Gas type: | natural gas, town gas, LPG, flue gas, biologically produced methane and air |
| Max. inlet pressure: | 600 mbar (8.5 psig) |
| Max. test pressure for testing the entire system: | temporarily < 15 minutes 2 mbar (29 psig) |
| Switching capacity: | DG..VCT, 24 – 250 V AC:
I = 0.05 – 5 A at cos φ =1,
I = 0.05 – 1 A at cos φ = 0.6. DG..VCT..G, 12 – 250 V AC: I = 0.01 – 5 A at cos φ = 1, I = 0.01 – 1 A at cos φ = 0.6. DG..VCT..G, 12 – 48 V DC: I = 0.01 – 1 A. DG..VCT, 30 – 240 V AC: I = 5 A at cos φ = 1, I = 0.5 A at cos φ = 0.6. DG..VCT..G, < 30 V AC: I = 0.1 A at cos φ = 1, I = 0.05 A at cos φ = 0.6. If the DG..VCT..G (DG..VCT..G) has switched a voltage > 24 V (> 30 V) and a current > 0.1 A once, the gold plating on the contacts will have been burnt through. It can then only be operated at this power rating or higher power rating. |
| Ambient temperature: | DG..VCT: -10 to +70°C (14 to 158°F) DG..VCTT: -15 to +60°C (5 to 140°F) |
| Construction: | RoHS-compliant pursuant to 2002/95/EC. Diaphragm pressure switch, silicone-free. Diaphragm: NBR. Housing: glass fibre reinforced PBT plastic with low gas release. Lower housing section: AlSi 12. Enclosure: IP 54 pursuant to DIN EN 60529 with standard socket to DIN EN 175301-803, IP 00 with AMP plug. Safety class: 1. |
