Option 2GPNI: Double non-inverting gas and pressure contacts
Back to Options.
Devices concerned: DGPT2 & DGP.
With the 2GPNI option, the device has two simultaneously switching magnetic bulbs and a double, simultaneous contact pressure switch. The device’s contacts have terminal outputs but cannot be inverted, as there are more than the maximum number of terminals on the electrical plate.
The contacts’ states for each of the four functions must be defined: NO, normally open and closed in case of a fault, or NC, normally closed and opened in case of a fault.
The 2GPNI option is used to transmit the same information to two different points, each with their own safety section. In this case, relaying is impossible as the relay coil itself depends on another power supply section.
