Introduction

Product Description
With the ESI 400 the status of 4 switches, reed contacts or all kinds of potential-free digital sensors can be
queried. No external voltage is required for the inputs.
The status LED on the upper side of the module signals the power supply and the status change of the inputs.
When input voltage is applied, the LED flashes briefly as confirmation of the status change.
The ESI 400 is equipped with hardware and software filters to reliably interrogate all types of mechanical switches
without flickering. The delay of the inputs is about 40ms.
The inputs are electrically connected to the 1-Wire network. Due to the complex filter technology, even long
connection cables between the module and the sensors are possible without disturbing influences on the inputs
and the 1-Wire bus. The working voltage of the digital inputs is approx. 5V.
The ESI 400 has a universal supply voltage input with 5V to 12V voltage.
We recommend the use of one of our 1-Wire hub modules.
