A Phoenix Contact product story
Edited by the Engineeringtalk editorial team Jul 25, 2003

Operational data and status information from automation installations can now be accessed easily from almost anywhere in the world using the new PSI rail-mounting industrial data/fax modem.

Operational data and status information relating to automation installations can now be accessed easily and inexpensively from almost anywhere in the world by using the new PSI rail-mounting industrial data/fax modem from Phoenix Contact.

Designed specifically to satisfy the requirements of demanding industrial users, this rugged modem incorporates extensive security features and integral surge protection.

Connected to the automation system via an RS232 link, the PSI modem can be used with dial-up or permanent connections to provide a wide range of functions, including data acquisition, remote diagnostics, remote maintenance, and program downloading.

To guard against unauthorised access, the unit incorporates password protection, along with call-back and selective call acceptance facilities.

A particularly useful feature for industrial applications is an alarm input.

When a contact connected to this input operates, the modem sends a user-definable stored message to either a mobile phone, using SMS, or to a fax machine.

This enables the unit to draw immediate attention to a problem, even if the main control system fails.

The alarm function may also be accessed using standard AT modem commands.

To allow its use in the widest possible range of applications, Phoenix Contact's PSI modem can operate from any supply voltage in the range 10 to 60V DC or 14 to 40V AC.

This feature, together with a power-saving sleep mode, makes it an excellent choice for use in battery- or solar-powered installations.

Designed for ease of installation and use, the PSI modem offers plug-and-play convenience, and is supplied with a user-friendly configuration software pack.

It is fully compatible with the public telephone systems used in Europe, the USA and Canada, and it uses the internationally recognised V.34 analogue data transmission standard.
