The TCW220 is an Ethernet data logger for general data acquisition, featuring two 10-bit analogue inputs, two digital inputs, and a 1-Wire interface for up to eight sensors (CO2, current, temperature, humidity, etc.). It also includes two Normally Open/Closed relays. All monitored parameters can be logged based on time or alarms, with a 36 day (minimum, 1-minute intervals) memory capacity. Logged data and real-time parameter values (in XML/JSON) can be periodically uploaded via HTTP POST.
The device supports remote relay control (WEB, SNMP, HTTP, Modbus TCP/IP) and local relay activation based on monitored parameters. It facilitates SCADA system development through HTTP POST command reception. Alarm notifications (email, SNMP trap) for up to five recipients and alarm status reports (HTTP POST with XML/JSON) are supported for all monitored parameters.
