digital and 1 analog input, 1-Wire interface and 1 relay output. It can be managed by WEB interface
and/or SNMP programs.
The relay can be activated either remotely (WEB, SNMP etc.) or locally - from presence/absence
of ping (echo request or echo replay). SNMP trap can be sent for every monitored parameter
(temperature, humidity, analog voltage and dry contact) if it goes outside of previously predefined
range. Special schematic is utilized for long 1-Wire support.
2. Features
10 Mb Ethernet connectivity;
Password protected, web based configuration and control;
1 digital input with " dry contact" and "logic level" modes;
1 analog input with 0 to 60VDC range;
1 relay with NO and NC contacts;
Long 1-Wire support for 1 temperature (TST1XX) or temperature/humidity (TSH2xx) sensor;
SNMP v.1 support;
SNMP traps sending for alert conditions;
VLAN support;
