New 1-wire sensors for the Audon Electronics TCW240 Ethernet Control Unit

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.

TME - Ethernet Thermometer Alarm Unit

TME is a simple temperature sensor with Ethernet interface. It measures temperatures ranging from -55°C to +125°C. Measured values can be read in several ways including TCP, UDP, HTTP (WEB), e-mail, SOAP, Modbus TCP and SNMP protocols. Thanks to this it is possible to choose a method suitable for particular application.

The temperature is sent in a simple ASCII format directly in degrees Celsius; there is no need of any additional conversion. It also enables communication with SNMP protocol (UDP) or sending an e-mail in case any of the pre-set limits is exceeded.

You can easily embed the temperature from TME to your WEB site using http GET. Measured temperature is also available in XML file or it can be sent as an http POST in XML format for further processing in a WEB service. (All temperature acquisition methods are on page 6.)

TME is configurable via WEB interface. TME is powered from an external PSU 5V (TME) or directly from ethernet network according to IEEE802.3af standard (TME PoE)

Low Cost Ethernet to Serial Converter

The eNET-232 Ethernet to Serial converter is a simple way of connecting any serial device, whether RS232 or RS485 to a Ethernet network. It features a simple setup procedure, ease of operation and automatic network recovery. Supplied with Programming examples and Virtual Serial Port software, to seamlessly add serial ports to your Network. The eNET-232 has a two serial ports, one RS232 and the other can be a RS232/422/485 RS485 port.

A pair of eNET-232's can be set up in Client-Server mode where they will send RS232 data between each other without any PC intervention.

Economical Ethernet Temperature/Humidity email Alarm

The HWg-STE web thermometer is an Ethernet based two channel alarm unit configured using a built-in web server. The HWg-STE web thermometer is configured using a built-in web server which can also show the current temperature (and humidity). If the temperature (or humidity) exceeds a specified threshold, an e-mail alert is sent. The HWg-STE Thermometer is also fully SNMP compatible. Free windows software HWg-PDMS for datalogging, graphical overview and MS Excel export is included.

The HWg STE represents an effective and economic solutions in the applications like air-conditioning failure, heating system monitoring, cooler/freezer monitoring, heating optimization and food storage.

Temperature Alarm and Monitor from Web Browser

The P8 series from Audon Electronics a low-cost Ethernet solution for temperature monitoring and alarm in server room, museum, medical and industrial applications. Simply connect to your LAN, open any web browser and begin monitoring.

Temperatures can be viewed in tabular or history chart formats. The history memory can hold 900 readings, with a variable store rate from 10 seconds to 18 hours. Stored history data can be downloaded to a PC file for further analysis.

The P8 series also have under and over temperature alarms. The units can email a warning message to up to three users, and can send SNMP alarm traps. The series also supports MODBUS TCP for integration with SCADA software. LabVIEW examples are available.

Control any GPIB Instrument over Ethernet

The GPIB-LAN controller from Audon Electronics converts any computer with a Ethernet port into a GPIB Controller or Device. In Controller mode, the GPIB-LAN controller can remotely control GPIB enabled instruments such as Oscilloscopes, Logic Analyzers, and Spectrum Analyzers. In Device mode, the GPIB-LAN controller converts the computer into a GPIB peripheral for downloading data and screen plots from the instrument front panel. In both modes, the GPIB-LAN controller interprets high level commands received from the host computer and performs the appropriate low-level GPIB protocol handshaking.

No special drivers are required and a wide variety of host software may be used to communicate with the GPIB-LAN. The GPIB-LAN controller supports static IP address and dynamic (DHCP) IP address. The controller’s network parameters can be configured using the supplied NetFinder application

Available ex-stock from only £149.

Ethernet based Environmental Monitor sends email Alarms

The Poseidon 3268 is a simple Ethernet based stand-alone device which can send an email alarm when up to 4 monitored temperature or humidity sensors exceeds their defined range. The Poseidon 3266 also has 4 contact-closure inputs which can be used to trigger alarms on state change and there are 2 relay outputs which can be used to reset servers, or switch on a fan, etc.

Temperature or combined temperature/humidity sensors can be connected via RJ11 cable using the 1-wire protocol. Sensors are simply connected in a serial chain using RJ11 cable. These can be up to 10m away from the Poseidon 3268. You can assign a name to each sensor and also define high and low alarm limits. When the parameter goes outside these limits, the Poseidon 3266 can send user defined email alarm messages and toggle the output relays.

Once the Poseidon 3268 is connected to the LAN, you can run the free UDP setup utility, which will search the LAN to find all attached devices. You can then specify your desired Network address parameters. Once this is done, you can simply access the I/O data from a web browser. There is also a flash-based version.

All sensor's values as well as alarm status information are available from XML files (temper.xml) and any application can log it from XML tags. The Poseidon 3268 also supports the Modbus/TCP protocol, so it is easy to integrate with common SCADA packages such as DAQFactory.

Typical applications include monitoring conditions in server rooms, switch-boards, cold-storage buildings, freezers and fridges and other environmental monitoring tasks.
