Ethernet data logger

TCW220 is an Ethernet data logger for general data acquisition applications. It has 2 analog inputs, with 10-bit resolution and 2 discrete inputs. It utilizes a 1-Wire interface for up to 8 Teracom 1-Wire sensors – carbon dioxide, 0/20mA, AC/DC current, temperature, humidity etc.) The Ethernet data logger also has 2 relays with normally open and normally close contacts.

All monitored parameters can be logged on a previous set time interval and/or on alarm conditions. The memory is large enough for at least 36 days with records on every 1 minute. The log file can be periodically uploaded on a dedicated server with HTTP Post.

XML/JSON file, with all monitored parameters, can periodically uploaded on dedicated server by HTTP Post. Like answer server can return commands for relay’s control. This is a way for building SCADA system.

The relays can be activated either remotely (WEB, SNMP, HTTP, MODBUS TCP/IP, etc.) or locally – from a status of monitored parameters. For every parameter email and SNMP trap for up to 5 recipients can be sent. Alarm alert also can be sent by HTTP Post with XML/JSON status files.
