A new range of 1-wire based sensor interfaces have been introduced for use with the TCW240B Ethernet control unit.
The
TCW240B is an Ethernet based multi-functional alarm and control unit
with built-in web server. It includes 4 digital inputs, 4 analogue
inputs and a 1-wire interface for up to 8 external sensors.
It
also has 4 relay outputs with normally open and normally closed
contacts. The relays can be activated remotely from the web interface or
from software using SNMP, XML and HTTP API commands. The relays can
also be automatically activated from the status of a monitored input,
such as a temperature, exceeding a set limit. A relay can only be
assigned to a single input, but every input can initiate a alert e-mail
or SNMP trap on alarm.
The
TCW240B also has a real time clock, so scheduled tasks can be
programmed in either single or with a continual daily/weekly basis.
Three
new 1-wire interface modules have now been introduced in addition to
the existing temperature and humidity sensors: the TCS200 is an current
module for both AC and DC currents up to 15A, the TSV200 is a voltage
module with a 60V input range and the TSA200 is a 4-20mA current loop
interface. All modules feature galvanic isolation and dual RJ11
connectors for easy daisy chaining on the 1-wire bus.
The
large number of digital and analogue inputs, the 1-wire sensor bus and
relay outputs makes TCW240B a good choice for various application such
as home and office automation and alarm systems, greenhouse and
agricultural control, industrial process control, IT system monitoring
and critical fridge/freezer monitoring and alarm.
