Industrial 4-Ch RS485/RS232 Digital Input/Output Module with Modbus RTU Protocol, Isolation Protection
$30.99
⚠️ Hardware Sub-Model Selection Required
The Analog Input (AI) format is hardware specific and needs to be validated prior to leaving the factory. The output cannot be changed between 4-20mA, 0-5V, or 0-10V by software. Please choose the correct AI sub-model from the drop-down menu before adding to cart.
Product Overview
The Valtoris 4CH-IO-RS232/485 is an industrial Remote I/O Controller for connecting field sensors to legacy RS485 or RS232 networks. It comes with native 4 Digital Inputs, 2 Analog Inputs and 4 Relay Outputs. It is a powerful edge device for SCADA data acquisition and remote control using the standard Modbus RTU protocol.
