The DSE855 communications device allows the monitoring of a single DSE controller with USB connectivity over a LAN or WAN connection. To achieve this the DSE855 utilizes its in-built web server or MODBUS TCP. In order to use over a LAN connection, the on-site router must be configured to be accessible from any global location.
DC SUPPLY CONTINUOUS VOLTAGE RATING：8 V to 35 V Continuous
CRANKING DROPOUTS Able to survive 0 V for 100 mS, providing supply was at least 10 V before dropout and supply recover to 5 V. This is achieved without the need for internal batteries. LEDs and backlights will not be maintained during cranking.
MAXIMUM OPERATING CURRENT：123 mA at 12 V/71 mA at 24 V
MAXIMUM STANDBY CURRENT：104 mA at 12 V/63 mA at 24 V
