The system solves the alarm indication problems come from process gas control distributed in plant and the remote monitoring to the competence offices.
The system is constituted by:
-FLOCONTROL (no RS485) 4 analog inputs for pressure transmitters 4-20mA, 10 digital inputs for ON/OFF sensors (pressare switches and NAMUR contacts), 4 pneumatic outputs, 1 output contact, 4 independent pneumatic outputs control, 1-2 switch over systems
-SW-GAS (no RS485) 4 digital inputs and 2 pneumatic outputs, 1 output contact, 1 switch over system
-SDAM D10 10 digital inputs ON/OFF (FLOCONTROL and SW-GAS outputs contacts)
-SDAM Shut-off A5 5 analog inputs for pressure transmitters 4-20mA, supply gas control
-SDAM Shut-off D10 10 digital inputs ON/OFF, supply gas control
-SDAM R Repeater of SDAM D10, SDAM Shut-off D10 and SDAM Shut-off A5 in network
Programming for SDAM D10/ SDAM A5/ SDAM D10 Shut-off/ SDAM A5 Shut-off units through P.C.; it is possible set the digital and the analog inputs parameters as: input identification, contact type (for digital inputs only), range of measurement and alarm thresholds (for analog inputs only), alarm priority, output relay configuration (for SDAM D10/ A5 Shut-off in use for solenoid valve) and area identification.
SDAM units can be supplied in box for surface or flush wall mounting.
The units can be connected in SDAMNet local network (RS485) to one or more SDAMGUARD units and/ or to P.C. for central monitoring guard station.
On P.C. can be installed the monitoring software SDAMNet SW; with the software licence an interface converter USB/RS485 is supplied for the connection between P.C. and the local network.
Two software versions are available:
-SDAMNet_Lite SW Monitoring base software
-SDAMNet SW Graphic software monitoring
Both versions have the following functions:
-Cyclic monitoring on peripherals SDAM observing alarms, fails and measurements
-Visual monitoring on monitor and acoustic signal activated by alarm presence
-Memory of events, measurements and fails
-SDAM peripherals programming in network
-Statistic elaboration of alarms
-Statistic elaborations of measurements
-Possibility to connect the local network by SMS with external operators
SDAMNet local network can be connected with MODBUS network through transcodification module A2M Converter.
