Introduction
Prosense S-DP4 Control Panel is able to provide automatic gas concentration reading and
protection against gas explosions. S-DP4 permanently transmits the gas concentration
measurement from detectors to the control unit. Before the gas concentration in the
atmosphere reaches the L.E.L., 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-DP4 Control panel can manage 4 analogue 4-20mA output gas detectors.
S-DP4 Control panel can manage explosive-flammable and toxic gas detectors as well as
oxygen detectors with direct connection to each detector via standard 4-20mA output.
Prosense S-DP4 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-DP4 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-DP4 Gas Control Panel complies to IEC 60079-0:2017 and 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.
