R2 Controls Introduces High Performance, Low-Cost Modbus Digital Remote Terminal Unit (RTU)

November 172004
· 8051-based Modbus Digital RTU provides industrial-strength serial communications capabilities for enhanced remote relay configuration and control

· Flexible, and fully integrated solution includes opto-isolated digital inputs with pulse counting and high current relay outputs

· High performance RTU provides remote relay configuration and control in a low-cost, compact footprint in enclosed form with screw terminal I/O interface

November 16, 2004 -- ROSEVILLE, CA -- R2 Controls announced general availability of the R301 Modbus Digital Remote Terminal Unit (RTU). The R301 Digital RTU is ideal for demanding field and industrial relay-based applications requiring remote configuration, monitoring, and control with a high degree of input and output isolation and high current output control capabilities.

Based on the Silicon Laboratories 8051 system-on-chip processor, the R2 Controls Modbus Digital RTU provides a low cost complete solution for programmable high-speed remote relay control with its integrated opto-isolated digital inputs, Modbus communications protocol, high power relay outputs and serial communications options.

“The R301 Digital RTU’s rugged design and flexible communications capabilities enable ease of adaptation into any remote industrial or field environment requiring high power remote relay output control, such as in oil and gas distribution systems, water flow monitoring and control applications and integrated multiple control points in large industrial complexes’” said Tim Hinchey, R2 Controls President & CEO. “The complete automation and integration of remote monitoring and controls with centralized common industrial control become highly feasible and cost-effective with deployment of one or more R301 Digital RTU’s”.

Specifications and Performance Highlights
The R2 Controls R301 Modbus Digital RTU is based on the latest in communications and processor technology and incorporates the Silicon Labstm C8051F230 microprocessor running at 22.1Mhz. The Digital RTU features 8 high-speed optically isolated Digital Inputs with pulse counting, 2 protected Digital Inputs and 8 Form 1C SPDT Relay Outputs. Input voltages levels can range from 3-40 volts AC or DC. The output relay contacts are rated at 10Amps/120V AC and have rubber snubber circuit protection. Field wiring is made easy with 5.0mm pluggable screw terminal blocks.

The R2 Controls Modbus Digital RTU operates at a supply voltage of 9-30V DC and may be used in a stand-alone mode as a programmable relay controller or connected via an RS-485 port to other RTU’s to create an expanded remote control environment. The industrial I/O is accessed via 56 screw terminals and standard DB9 serial connectors

Price and Availability
The R301 Modbus Digital RTU is priced at is $299 (quantity 1) and is available for immediate delivery.
