SAN People - Digital I/O

The EtherPAD Digital I/O is a versatile device that can be used in stand-alone, DIN rail or 19" rack-mount applications. The Digital I/O provides a powerful interface for connecting digital signals to Ethernet. Remotely monitor and control digital signals using SANscript to provide a customised solution. Use the sample script to send email alerts and log to file or html. Visualise the I/O status via a web browser or SNMP manager.

This product range includes the following hardware configurations:
10/100Base-T Ethernet to RS232. RS422 and RS485 with 4 MB Flash Memory.

4x Digital Inputs: Internal Supply Voltage of 3.3V to 3.5V across the pins can be switched by simply connecting a relay's output to the pins.
2x Digital Outputs: Output relays are capable of a maximum switching voltage of 24V DC/AC and a maximum switching current of 1A. Outputs can be configured as normally-open or normally-closed via an internal jumper setting.
1x Analog Input: There is no over current protection. Analog range is between 4mA and 20mA. External circuitry voltage required should ideally be between 6V and 24V.

Data Logging:
Selectable Time & Date Stamping of logged data in Text format. Email or FTP transfer of files or downloadable via a Web Browser. More info is available here.

Scripting:
SAN Script creates powerful custom applications which includes embedding data into the web server. Serial & Network data can be manipulated as it traverses the EtherPAD. View our online demos to see some scripting examples in action. Scripting documentation and code samples can be found here.

PPP:
PPP option allows IP packets to be transported over the Serial line with an externally connected modem. The EtherPAD can be configured as an access server or to dial out on-demand (or both). More info is available here.

Dynamic Routing:
Connect to a remote network (LAN) via an externally connected modem and with the PPP option enabled. You can also connect two remote networks together. With the Routing option, IP packets from the Serial PPP link traverse the EtherPAD and are forwarded onto the remote LAN via the Ethernet interface. The EtherPAD becomes a gateway between two networks.

Modbus Scripting:
SAN Script commands for manipulating Modbus Data.

Modbus Bridge:
Configure the EtherPAD for a Master or Slave Bridge, converting Modbus TCP/UDP to Modbus ASCII/RTU. More info is available here.
