Communication Modules are offered in two models covering
standard industrial buses: Ethernet, RS-232, RS-485, and USB. Host
software interfaces to the system using the Modbus TCP or RTU
protocol. When using the Ethernet interface, up to four simultaneous
socket connections are supported and each socket can process up to
four simultaneous Modbus TCP transactions. Serial communications
over RS-232 or RS-485 can be run at baud rates as fast as 921.6kbps.
Another useful feature of the system is the capability to store acquired
data locally for later analysis. Each communication module has an easily
accessible and removable 4GB micro-SD memory card that can be
used to log data from all input modules.
To power the system, a 7-34VDC power source is connected to the
communication module. Regulated and protected supplies within the
module then provide power both to the internal circuits and to all mod-
ules in the system. When many high power I/O modules are used in a
system, load-sharing power boost modules can be installed in standard
I/O module slots to provide the necessary additional power.

Analog Input Modules
interface to a wide range of standard
industrial sensors and equipment, including volt, millivolt, milliamp,
thermocouple, RTD, potentiometer, strain gage and frequency. Four to
16 channels of input on the modules results in physically small control
systems and low cost per channel. Signal ranges are user selectable
and offered in both differential and single-ended configurations. Chan-
nels can be independently configured and alarms can be set to match
the most demanding applications.
