ACREL Remote Terminal Unit with RS485 Modbus-RTU
ACREL Remote Terminal Unit with RS485 Modbus-RTU is a remote terminal unit for collecting digital switching signals and providing remote relay control in intelligent distribution and industrial automation systems. Available configurations include 16-channel and 32-channel digital input models, plus an 8-channel digital input and 8-channel relay output model. RS485 communication with Modbus-RTU allows collected field information to be transferred to an upper-level monitoring system.
The ACREL Remote Terminal Unit with RS485 Modbus-RTU is intended for applications where switching information needs to be collected at a field location and made available to a higher-level monitoring or control system.
The series is particularly suited to intelligent power distribution and industrial automation. The available models provide different digital I/O arrangements, making it possible to match the RTU to the required number of field signals.
How it works
- Field switching signals are connected to the ACREL Remote Terminal Unit with RS485 Modbus-RTU's digital inputs.
- The RTU collects the input status and communicates the information through its RS485 interface using Modbus-RTU.
- Where remote output control is required, the ARTU100-KJ8 provides eight relay outputs with normally-open contacts.
- The collected information can be exchanged with an upper-level computer or monitoring system.
- The manufacturer manual also documents optional Ethernet and wireless communication configurations within the wider ARTU100 platform.
Why choose this product?
- Flexible I/O configurations - K32, K16 and KJ8 models are available for different digital signal requirements.
- Modbus-RTU communication - provides a widely used industrial communication method over RS485.
- Remote relay control - the KJ8 model combines digital input monitoring with relay outputs.
- Suitable for distributed systems - the RTU can collect signals at field locations and pass the information to a central monitoring system.
- Expandable ARTU100 platform - the manufacturer's manual documents additional optional I/O and communication modules for the broader ARTU100 architecture.
Benefits
The ACREL Remote Terminal Unit with RS485 Modbus-RTU can reduce the need to run individual field signals directly back to a central control location by providing local signal acquisition and communication.
Its different I/O configurations also make it suitable for installations ranging from smaller digital monitoring requirements through to systems requiring a larger number of switch inputs.
