Avoid the extra cost of an additional controller and effort of maintaining multiple applications. Start with a Digi Z45 Industrial Controller and add I/O by connecting Digi Z1201 expansion modules for a solution tailored to your system.
With support for various I/O combinations — relays, digital, analog, pulse, inputs and outputs — the expandable Digi Z1201 I/O module provides monitoring and controlling for use cases requiring unique I/O combinations.
On-device logic is supported from anywhere by Digi’s Z45 Industrial Controllers. Our controllers perform simple to medium complexity control logic, similar to that of a Programmable Logic Controller (PLC).
Unlike a PLC, our controllers are designed for remote, distributed I/O applications in a single end-to-end solution. Data communication between Z45 Industrial Controllers and Z1201 modules is provided by a 2-wire RS-485 connection with addressing and individual pin function established by program control using our Automation Control Application.
Digi Z1201 is a 16-pin, multifunction I/O module consisting of 8 collector outputs, and 8 multifunction inputs, each of which can be configured under software control for analog, digital or pulse operation. The module can be daisy-chained for expansion beyond a single I/O module.
Manage from Digi Axess — let Digi stand watch

Digi Axess provides a complete snapshot of your network and the equipment behind it. Know as much as you want, or as little as necessary, in order to make informed decisions. Sensor data is processed at the edge and passed to Digi Axess to offer a central point from which to manage all of your assets.
