IO290: Digital I/O Module with Isolated Inputs and Solid State FET Relay Outputs

IO290

Digital I/O Module with Isolated Inputs and Solid State FET Relay Outputs

The IO290 I/O module is a digital input and output module with Simulink^® driver blocks and features optically isolated non-polarized inputs with broad voltage compatibility and fully protected high-side FET output switches with high output currents.

Given its broad voltage range, input isolation and high current outputs, the IO290 I/O module can be used in a wide range of applications, for example in the industrial automation, aerospace and automotive sectors, including industries where electrical noise, high common-mode voltages and transient voltage spikes are an everyday occurrence.

This I/O module is ideal for 12, 24, and 28 VDC actuator control and HIL applications using MATLAB^® and Simulink^®.
