The USR-IO series is an advanced and expandable I/O controller lunched by PUSR, allowing for the desired quantity of I/O through combinations of the different model. When used with PUSR's M100 or M300, it enables remote control of IO devices. With its unique hardware design, it saves time on installation or removal, featuring push-in terminals that allow users to connect on-site without the need for tools. All these designs makes it an ideal solution for a variety of industrial data acquisition applications.
The USR-IO modular controller supports standard Modbus RTU for data acquisition and control, making integration into control systems extremely straightforward.
Industrial Grade Design
For dry contacts device, users need to connect the USR-IO's power in the whole circuit to detect the status of IO devices, such as detecting the status of switches, buttons, etc.
For wet contact devices, they output voltage signals such as high and low levels, pulses, etc. These devices already have an internal power source and do not require additional power supply. They can be directly connected to the terminals of the USR-IO controller, such as infrared detection, liquid level detection, smoke detection, etc. For the USR-IO controller, the input voltage range is 9-36V. If it exceeds this range, the device's status cannot be detected correctly.
For two-wire 4-20mA sensors, the sensor itself only has 2 wiring terminals: power + and signal -. These terminals serve both as power supply and signal transmission channels. In this scenario, connecting the sensor's power + to the USR-IO's power + and the sensor's signal - to the USR-IO's AI interface, while connecting USR-IO's COM to the power -, completes the setup.
In the AO loop, there is no need to connect to a power source.
In the AO loop, there is no need to connect to a power source.
Applicable when the current is less than 3A. If connecting high-power loads, replace the lighting fixture in the diagram with a relay or an AC contactor.
When using multiple IO controllers in combination, only one power supply is supported. Please do not connect multiple power supplies for power input.
Dimensions: 79.6*28*110mm
The USR-IO can be used with PUSR's M100 or M300, which can enable remote control of IO devices. And screwdrivers and other tools are not required for any part of the hardware installation, which can reduces the amount of time required for installation and removal.
The USR-IO modular controller uses direct-insertion spring terminal blocks, making wiring more convenient.
Integrating the IO controller into automated production line equipment, gathering and controlling device actions via RS485, effectively reduces labor costs and enables unmanned supervision of the production line.
Connecting the water heater, access control system, motorized curtains, lighting fixtures, and other devices to the IO controller, and integrating them with the control host through RS485 Modbus RTU, enables intelligent home automation and supervision.
