Versatile: 
Up to 12 sensors, incl. all CS sensors 
(consumption, dew point, pressure, current, 
KTY, PT 100, PT 1000) are identified auto-
matically by DS 500. Optional analogue 
sensors (0/4..20 mA, 0…1/10/30 V, pulse) 
can be configured easily and quickly. 
Digital sensors can be connected via
RS 485, Modbus RTU and SDI.
Flexible: 
Network-compatible and worldwide remote 
data transmission via Ethernet, integrated 
webserver.
Alarm relay/ fault indication: 
Up to 32 threshold values can be configu-
red freely and allocated to 4 different alarm 
relays. Collective alarms are possible.
