Ethernet data logger Overview TCW220 is an Ethernet data logger for general data acquisition applications. Its analog inputs, with 10-bit resolution, can be used for monitoring of 0-10 V and 4-20 mA sensors. Digital “dry contact” inputs can monitor discrete detectors – door sensor, smoke detector, AC voltage presence etc. TCW220 supports up to 8 TERACOM 1-Wire sensors for temperature, humidity, carbon dioxide, 0-20mA, AC/DC current, etc. The Ethernet data logger has 2 relays with normally open and normally closed contacts. All monitored parameters can be logged on a previous set time interval and/or on an alarm condition. In the internal nonvolatile memory can be stored up to 70000 records. The log file can be periodically uploaded to dedicated server by HTTP Post. Applications • Environmental monitoring – The device can monitor temperature, humidity, barometric pressure, CO2 etc. • Server room monitoring - The device can monitor AC power supply, smoke concentration, door opening, battery voltage, room temperature, and control the cooling system. • Industrial process automation – Monitoring of industrial sensors with 0-5V, 0-10V and 4-20mA output. • M2M systems - The device can send periodically information to monitoring server and execute its commands. • Data logging of facilities - The device can log and display the measured data. It can be used as a standalone device or as a part of SCADA system. Basic features • • • • • Data Logger for 70000 records; Graphical view of logged data; Automatic upload of logged data in CSV format; MODBUS/TCP support; SMTP support for e-mail alert SNMP v2 support with trap alert; HTTP Post service with API commands; XML/JSON status report files; Dynamic DNS support; Back-up/Restore of c
