Ethernet data logger TCW220

TCW220 is an Ethernet data logger with MODBUS TCP/IP support, the right choice for remote automation.


TCW220 is an Ethernet data logger for general data acquisition applications. It has two analog inputs, with 10-bit resolution and two discrete inputs. It supports a 1-Wire interface for up to eight Teracom 1-Wire sensors – carbon dioxide, 0/20mA, AC/DC current, temperature, humidity, etc.) The Ethernet data logger also has two relays with normally open and normally closed 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 minute. The log file can be periodically uploaded on a dedicated server with HTTP Post.

XML/JSON file, with all monitored parameters, can periodically be uploaded on the 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 five recipients can be sent. Alarm alert also can be sent by HTTP Post with XML/JSON status files.
