MAQ20-COM, Communications Base Unit
- Interface up to 24 I/O Modules
- Connect Host Computer & MAQ20 System
- Communicate Using Ethernet TCP/IP, USB, RS-232 or RS-485
- Store Acquired Data Locally
- Communications Interface-to-Bus Isolation 50 VDC
The MAQ20-COM base unit is offered in two models and provides the connection between a host computer and a MAQ20 data acquisition system.
The MAQ20-COM supports up to 4 simultaneous Socket connections with Ethernet TCP/IP. The MAQ20-COM can support up to 24 I/O modules, each with up to 8 inputs, providing an expansion of up to 192 parameters.
A very useful feature of the MAQ20 is the capability to store acquired data locally for later analysis.
There are a number of Analog and Digital I/O modules that offer a wide range of application solutions.
Software is available for configuration, Graphical Display (GUI / HMI) and Report Generation.
