... the far end of Ethernet
ethernode® Analog: ETH-A7-3A4IO
- Two serial interfaces: 1xRS232, 1x RS232 with HS or RS485, RS485 termination switchable

- Amplification failure @25°C < 0,05%
- Offset failure @25°C < 0,15°C
- 4 opto-decoupled inputs 24V
- 4 High-side (P-switching) outputs 1A@24V
- 200µs switching-speed
- nodeAccess for direct I/O-access from Windows® PCs
- Virtual COM interface in Windows®-PCs
- mCAT-Server-Pages (mSP) opens I/O-functions for the webbrowser
- Optionally remote control with PoE - therewith isolated interfaces
ethernode® ETH-A7-3A4IO is a full featured control unit at the Ethernet. It offers three high-precision analog inputs for PT100, thermocouples or 4..20mA process current, in addition 4 digital inputs and 4 P-switching 24V outputs, two serial interfaces and optionally an LCD.
It is hard enough to get a Pt100 reasonably accurate into the Ethernet, but this small box does more: The precision of the 3 analog inputs is sufficient for real measuring, the internal buffered memory allows data logging and in the display version (A7L) you can even show a rough x/t or bar graph. Even more: With the digital outputs stand-alone two-step controls can be implemented, the beeper acoustically signals excess temperatures while an e-mail over the server activates an SMS. You also could assign data to a code read from a bar-code-reader on the RS232 line or read some scales over RS485.
Furthermore available: Standard version ETH-A7-2SER with only 2 serial interfaces and without 24V-I/O.
