The Horner SmartMod+ series represents a significant advancement in distributed I/O technology, offering a versatile and compact solution for industrial automation systems. Designed by Horner Tianjin Automation Technology, these modules provide a reliable way to expand the I/O capabilities of PLCs, HMIs, and SCADA systems using the industry-standard Modbus RTU and Modbus TCP protocols.

High-Density and Scalable I/O

The SmartMod+ is engineered for efficiency, featuring a slim-line housing that maximizes rail space in control cabinets. The series includes a wide array of modules, covering digital inputs/outputs (DC and Relay), analog inputs (Voltage, Current, RTD, and Thermocouple), and analog outputs. This variety allows engineers to customize their I/O mix to fit specific application requirements, from simple machine control to complex process monitoring.

Robust Communication and Integration

Standard SmartMod+ modules utilize RS-485 serial communication with Modbus RTU, ensuring compatibility with a vast range of industrial hardware. For modern network architectures, Ethernet-based models supporting Modbus TCP are available, facilitating high-speed data exchange and remote diagnostics. Each module features built-in galvanic isolation up to 2000V, protecting the central control system from electrical noise and ground loops in harsh factory environments.

Key Features

• Easy Configuration: Simplifies setup through standard Modbus registers and Horner configuration tools.
• Status Monitoring: Integrated LED indicators for power, communication, and I/O status provide instant local diagnostics.
• Flexible Wiring: Removable terminal blocks simplify installation and maintenance procedures.
• Wide Compatibility: Designed to complement Horner OCS controllers while remaining fully compatible with any Modbus-capable master device.

Typical Applications

• Distributed data acquisition in large-scale manufacturing lines
• Building automation and HVAC control systems
• Remote monitoring of energy and utility infrastructure
• I/O expansion for compact PLC systems
