TSC200-15 – new current sensor

TSC200-15 is our new current sensor with 1-Wire interface, member of family TSC200 current sensors.

TSC200 - 1-Wire current sensorIt can be used for either AC or DC current monitoring. The mode of operation is changed by user. Input AC current range is 0.3 to 15 Arms, while DC current range is ± (0.3 to 15) A.

TSC200-15 is based on fully integrated Hall-effect current sensor IC, that provide galvanic isolation without opto-isolators or other costly isolation techniques. High isolation voltage and low primary conductor resistance make the sensor suitable for current and power measurements for building’s management systems (BMS), monitoring and control of batteries, solar systems, industrial automation etc.

TSC200-15 has two RJ11 connectors, for easy daisy chain arranging of 1-Wire bus. It is supported by TCW240B Ethernet controller. More detail can be found on the product page.

TCW240B – Remote and local scheduled control

TCW240B is first member of our new series Ethernet controllers – TCW2xx for remote control and monitoring over IP.

TCW240B-data-acquisition-moduleIt has a lot of new features – real time clock for time scheduled control, SSL support, 100MB connectivity, SNMP v2.0, multi sensor 1-Wire support with auto detection, Fahrenheit/Celsius degree support,  multiplier and offset for analog inputs, extended HTTP API protocol, push mode for client-server systems etc.

TCW240B has a few hardware option in comparison with TCW1xx series – extended temperature range from -20 to +70°C, extended supply voltage range from 8 to 32VDC, 16 bits microcontroller for better performance etc.

TCW240B can be used in various application like mushroom and winery environmental monitoring and control, environmental monitoring and control of server rooms, heaters or coolers control, scheduled control of processes, industrial process automation etc. More details can be found on TCW240B product page.

New firmware for control and monitoring devices

New firmware versions (2.0) for popular controllers (TCW122B-CM and TCW181B-CM) for control and monitoring have been released.

new-fwNew firmware versions (2.0) for the discontinued products TCW121B and TCW180B have been also released.

The changes are:

– much faster WEB interface;
– better overall stability;
– HTML API commands can be send without authorization;
– update through WEB interface;
– HTML API commands and XML reports are added and VLAN and MAC filtering are removed
(for TCW121B and TCW180B).

Only first update, from version 1.xx to 2.xx, should be made in two steps. First step is to upload “Loader” and second step is to upload actual 2.xx version. Detailed instructions are posted on the device’s pages. Every next update will be made by WEB interface, without any software tool. Once the controller is upgraded to 2.xx, it can’t be downgraded to 1.xx.
