The Industrial Digital I/O Ethernet Data Acquisition System is a member of our EDAS family of products. EDAS systems communicate with PC's and other computers over Ethernet and Internet networks. They utilize the open systems environment of Ethernet to acquire data from any number of remote locations. Data can then be made available for use by other networked resources or for further processing by plantwide software and/or databases, including your Intranet or Internet information pages.
Open System
EDAS units communicate over any Ethernet network (LAN) using industry-standard TCP/IP protocol, providing a non-proprietary interface to virtually any host. Each EDAS unit has a TCP/IP stack built-in and receives its own unique network IP address configured through the on-board RS-232 serial port.
Digital I/O
Each Industrial EDAS provides 16 digital I/O channels, individually configurable as inputs or outputs. Through the use of PCI-1101 to 1106 Series isolated signal conditioning modules, I/O ranges of 10 to 280 volts are supported. All inputs and outputs are protected from damage under power on or power off conditions.The Industrial EDAS supports a number of digital I/O functions.
Inputs can be used to read the current status of digital signals, detect digital signal state-changes (latch a state), and count signal state-changes for low speed counting applications (less than 100 Hz).
Outputs can operate in simple on/off fashion, or can be programmed for specific delay times and on/off times for control and timing applications. In addition, eight of the digital output channels can be individually configured for predetermined output states at power-up.
Serial I/O
EDAS systems also feature serial I/O capability. In addition to IP address configuration, the onboard RS-232 port can be used for interfacing to RS-232 devices. When the port is in "Command" mode, EDAS can monitor and control any device with RS-232 connectivity, including terminals, bar code scanners, instruments, scales, gauges, smart sensors, and machines.
EDAS systems are availiable with optional RS-485 port. These units can monitor and control any number of instruments, sensors and machines over a RS-485 network.
Data Retention
The Industrial EDAS protects your data in the event of a power outage. After power is lost, the unit will retain state and count values on each channel for up to five days.
Operation
EDAS units act as application servers, providing I/O functions to clients on the network. They operate in both synchronous and asynchronous mode. In synchronous mode, a client polls the unit for digital input values and counter data, or to set output values. Asynchronous mode allows the unit to send data based on change-of-state or alarm conditions.
Enclosure
The Industrial EDAS is housed in a NEMA-12 (IP54) rated enclosure, making it suitable for industrial indoor use and providing protection from dust and noncorrosive liquid drip. The enclosure houses any PCI-1101 to 1106 Series opto-isolator modules your application requires. It comes with two blank side flanges that can be punched as needed for routing cables and wiring. The hinged lid provides easy access to the circuit board and signal conditioning isolation modules, facilitating on-line maintenance and trouble-shooting.
