Half bridge explosimeter input
It is possible to configure a device with an Ex05 remote explosimeter probe or a SX202 as an
external probe. In the below configuration, the input is of type Combustible Gas Detector (X)
and the cartridge is of type E.
With half bridge explosimeter probe (SX202, MTHX), the
device is designed as: DM-**6-****-X**-#*-***-*-*-*
With the external half bridge explosimeter detector (EX05,
EX09), the device is designed as:
DM-**6-****-W**- E*-***-*-*-*
In that case, an input of the cable gland or an accessory in
replacement of the cartridge enables the connection between
the hosted sensor and the device.
In order to operate this analogue input, an additional
electronic card (PIE3521) is added above the numeric card.
Using this board leads to a connection between 0V from power supply and housing
ground.
The cross section of the wires of the connection cable of the probe must be between 0.9 and
1.5mm². The table below shows the maximum cable lengths according to the cable section.
