Wolf-8ADio1Ro
8 Configurable I/O8 multifunction I/O ports, 1 Omron relay, RS-485 Modbus RTU on a Linux platform — for sensor-heavy automation, HVAC, access control, and PV monitoring.
Why Wolf-8ADio1Ro
Versatile Mixed-Signal I/O
8 ports, each independently configurable as digital input (30 V DC), digital output (350 mA), analog input (0–10 V or 4–20 mA), NTC temperature sensor, or Wiegand reader. One expansion card covers almost any sensor or signal type.
Built for Sensor-Heavy Projects
Connect temperature sensors, pressure transmitters, flow meters, and access readers all to one controller. 12-bit ADC with 4–20 mA and 0–10 V support.
Connect to Any Protocol
Talk to field devices over RS-485 Modbus RTU, and forward their data to your cloud or control system via MQTT, REST API, or Modbus TCP — over Ethernet or 4G/LTE. One unit links your field equipment to your software.

Use Cases
HVAC Monitoring & Control
Connect temperature, humidity, and pressure sensors via analog inputs. Control HVAC units via the relay. Receive setpoints via MQTT, run local logic when the cloud is offline.
Access Control
Connect Wiegand card readers via multifunction ports for door access. Trigger the relay output for door-strike control. Log events and report via MQTT or REST API.
PV Park Monitoring
Read irradiance sensors, temperature probes, and current transducers via 4–20 mA and 0–10 V inputs. Monitor panel health and use the relay for safety disconnect.
