Introduction
Prosense S-DP8 Control Panel is able to provide automatic gas concentration reading and
protection against gas explosions. S-DP8 permanently transmits the gas concentration
measurement from detectors to the control unit. Before the gas concentration in the
atmosphere reaches the Lower Explosion Limit (LEL), the control panel is able to shut off a
gas valve, cut off power and turn on an alarm via activating relays when correctly integrated
to related control devices. Prosense S-DP8 Control panel can manage 8 gas detectors with 4-
20 mA analogue signal output. S-DP8 Control panel can manage explosive-flammable and
toxic gas detectors as well as oxygen detectors with direct connection to each detector via
standard 4-20 mA output.
Prosense S-DP8 Control panel has two levels of alarm which are adjustable according to the
measuring range and one fault alarm for the detection loop. Individual relays per function
ensure remote controlled output. There are 4 relays on the panel. Two of them used as
alarm relays and configured as ALARM-1 and ALARM-2. There is one FAULT relay and one
AUX relay. The AUX relay can be defined as ALARM-1, ALARM-2 or ALARM-3. ALARM-3 is not
a level based alarm but it is an alarm driven by digital input connected to another external
device.
S-DP8 has 128x64 LCD screen on the front panel to show status of each detector. This LCD
screen and menu keys allow user to set correct properties for each detector like gas
concentrations by gas type, measurement unit, and range and alarm levels.
S-DP8 Gas Control Panel complies with IEC 60079-29-1:2016 standard requirements. Please
refer to the certification label on the control panel to identify the type of certification that
relates to the product supplied.
