Signal Conditioning and System Expansion
Interfacing embedded computers to real-world signals is straight-forward with our XIO series of System Expansion boards. Mix-and-match among functions to meet your application, such as high-current relay outputs or AC/DC inputs.
Standard features include screw-terminals for convenient wiring to field devices, and built-in status LED's which clearly show each boards operation. For ease of installation all XIO series boards are designed to mount in one of three ways: by using standoffs, track mount, or by attaching to a DIN rail using adapter clips.

XIO-RLY8
8 Channel Relay Output Board with Qwiic/Stemma QT I2C Interface
The XIO-RLY8 is an 8-channel relay output board that adds industrial-grade switching capability to any device with I2C communications including Raspberry Pi, ESP32, Arduino, Microcontrollers, and FPGAs.
Dual Qwiic/Stemma QT connectors allow fast and easy system setup. In addition, the I2C circuitry has been engineered to operate at either 3.3V or 5V and is rated up to 400 kHz making the XIO-RLY8 highly compatible.
Key Features- I2C Interface
- Eight isolated 10A SPDT (Form C) relay outputs
- Operates from 5V bus power or an external 8-30VDC supply
- Built-In Set and Reset relay control functions ease software development
- LEDs provide instant visual indication of relay and board activity
- Field wiring Screw-Terminals accept 12-24 AWG wires
- Mounts using DIN rail clips, Standoffs, or Track Mount
XIO-RO8
Relay Output Board
The XIO-RO8 accepts up to three 8-bit TTL/CMOS digital ports and uses one of the ports to control eight isolated SPDT (Form C i.e.; NO/NC) relay outputs. Dual IDC input headers directly support the two most common pinout arrangements for digital I/O ports. The XIO-RO8 operates from a single +5Vdc supply which can be provided by the Host, through either of the IDC headers, or externally by means of a two-position removable screw-terminal strip.
Key Features- Parallel Interface
- Convert any 8-bit digital port to eight 10A form C relay outputs
- Removable Screw-Terminals accept 12-24 AWG wiring
- Port-Wide Pull-Up, Pull-Down, and Invert-Logic to match most any host circuitry
- 5Vdc only power requirement
- On-board relay driver logic with individual LED status indicators
XIO-DI8
Optically Isolated Digital Inputs
The XIO-DI8 performs the interface function of isolating and conditioning input voltage signals into levels compatible with standard 8-bit TTL/CMOS digital ports, such as those found on Single-Board-Computers and Microcontrollers. Eight optically isolated and non-polarized input channels allows any combination of DC or AC signals to be monitored. In addition, low-pass filters can be optionally enabled for the reliable measurement of AC or noisy DC signals.
Key Features- Parallel Interface
- Use a devices 8-bit input port to monitor AC and DC signals
- Independently set input voltage range on each channel
- Input filters conditions AC and noisy DC field signals
- Removable Screw-Terminals accept 12-24 AWG wiring
- 5Vdc only power requirement
