TCW220 - Ethernet Datalogger for general data acquisition applications

TCW220 is an Ethernet data logger for general data acquisition applications. It features 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 at a pre-set time interval and/or under alarm conditions. The memory is large enough for at least 36 days with records every minute. The log file can be periodically uploaded to a dedicated server using HTTP Post.

The XML/JSON file, with all monitored parameters, can be periodically uploaded to the dedicated server via HTTP Post. As a response, the server can return commands for relay control. This is a way to create a SCADA system. The relays can be activated remotely (WEB, SNMP, HTTP, MODBUS TCP/IP, etc.) or locally - by a monitored parameter's state. For each parameter, emails and SNMP traps can be sent to up to five recipients. The alarm notification can also be sent via HTTP Post with an XML/JSON status file.
