This selection guide covers all EdgeIO Controllers — compact, expandable industrial controllers that integrate data acquisition, protocol conversion, logic control, and remote maintenance into one device. Choose the right model based on your requirements.
All EdgeIO controllers share the same hardware platform: 1-3 I/O expansion slots, dual Ethernet with integrated switch, isolated RS485, web configuration, and wide‑temperature operation (-40°C to +85°C). The only difference is the uplink protocol.
| Model | Uplink Protocol | Best For | Key Feature |
|---|---|---|---|
| BL190 | Modbus TCP | PLC expansion, SCADA integration | Native Modbus TCP, 15 simultaneous clients |
| BL191 | OPC UA | Industry 4.0, IT/OT integration, secure communication | X.509 certificates, AES-256, IEC62443 compliant |
| BL192 | MQTT | Cloud IoT, remote monitoring, energy systems | Direct to AWS/ThingsBoard |
| BL192Pro | MQTT + Modbus TCP + OPC UA | Multi-protocol edge IoT gateway | Three protocols in one, most flexible |
| BL193 | SNMP | Data center, telecom, network room monitoring | SNMP v1/v2c/v3, standard MIB, IT/OT bridge |
| BL194 | EtherNet/IP | Rockwell Automation systems, discrete manufacturing | Native EtherNet/IP, direct to ControlLogix/CompactLogix |
| BA190 | BACnet/IP | Building automation, HVAC, lighting, access control | BACnet/IP standard, building management systems |
| BA190Pro | BACnet/IP + MQTT + Modbus TCP + OPC UA | Smart building HVAC, multi-protocol building controller | Four protocols, most versatile for buildings |
Protocol: Modbus TCP
Native Modbus TCP controller that works as remote I/O for Modbus TCP masters (Siemens, Schneider, Delta, etc.). Supports 15 simultaneous Modbus TCP clients.
Protocol: OPC UA
OPC UA server that converts Modbus RTU/TCP data to OPC UA automatically. Supports X.509 certificates, AES-256 encryption, and role‑based policies — compliant with IEC62443 cybersecurity standard. Bridges OT sensors to IT systems (SCADA, MES, ERP, cloud).
Protocol: MQTT
Native MQTT controller with direct cloud connectivity — Alibaba Cloud, Huawei Cloud, AWS IoT, and ThingsBoard. Collects Modbus RTU data and publishes to MQTT brokers.
Protocol: MQTT + Modbus TCP + OPC UA
Most flexible EdgeIO controller. Supports all three uplink protocols — MQTT for cloud, OPC UA for IT/OT integration, and Modbus TCP for traditional PLC/SCADA systems. One device covers all bases. Best for complex projects with mixed requirements.

Protocol: SNMP
Converts industrial sensor/actuator signals into standard SNMP MIB objects. Supports SNMP v1/v2c/v3 with encrypted communication. Directly integrates with enterprise IT network management systems (NMS). Ideal for data center monitoring, base stations, and smart campuses.
Protocol: EtherNet/IP
Native EtherNet/IP adapter (slave) for Rockwell ControlLogix, CompactLogix, and Micro800 PLCs.
Protocol: BACnet/IP |
BACnet/IP controller for building management systems (BMS). Connects HVAC, lighting, security, access control, elevators, and water systems. Enables centralized monitoring and control of building devices through standard BACnet/IP protocol.
Protocol: BACnet/IP + MQTT + Modbus TCP + OPC UA
Most versatile building automation controller. Supports BACnet/IP for BMS integration, MQTT for cloud, OPC UA for IT systems, and Modbus TCP for legacy equipment. Four protocols in one device. Ideal for smart buildings requiring both local BMS and cloud connectivity.
