ALTO WebIO

Product catalog summary

Overview
The ALTO WebIO is a remote input/output module designed for Ethernet TCP/IP communication, suitable for data acquisition in industrial, safety, and harsh environments. It features smart pre-installed functions, pre-formatted ModbusTCP mapping, and configuration via HTML pages for quick startup.

Mechanical and Sturdiness
The module is housed in a sturdy aluminum case with industrial-grade paint, measuring 145 x 128 x 72 mm. It offers IP30 protection, disconnectable connectors, and quick anchoring on a DIN rail. It is designed to withstand electromagnetic interference (EN 50081-2) and operates in temperatures from -20°C to +70°C, with a storage range of -40°C to +85°C. The MTBF is 12 years minimum.

Communication
The module supports one Ethernet 10 Base T channel using the Modbus TCP protocol, one RS232/RS485 channel, and one RS232 channel, both using the Modbus protocol.

Module Range
Various module configurations are available, offering different numbers of logical inputs, outputs, and analog inputs/outputs. Modules can operate on 24Vdc, 12Vdc, or 230Vca power.

Startup and Configuration
Upon power-up, the ALTO WebIO seeks an IP address from a DHCP or BootP server. Configuration is done through a web browser, allowing the operator to set server addresses, email wording, passwords, and more. It also allows for online input state display and output forcing.

Local Functions
The module includes input filtering, edge counters, duration counters, output position withdrawal on Ethernet failure, and output blinking.
