Remote Control

The NetMan system has been designed to facilitate remote control for Utilities and Industry alike. Based on a modular concept and with in-built digital data radio technology these provide a cost effective easy to use solution for remote control and telemetry applications. Designed for low to medium I/O count, the unique repeating technology used by the NetMan digital data radios mean the user gets a wide area coverage system for a very low cost. Each unit is designed to receive and transmit messages to other units in order to build up a wide area network. High speed over the air protocol allows for extremely fast messaging which translates in to a high speed control and monitoring infrastructure. The NetMan system consists of two main elements, the RNO (Radio Network Outstation) and an RTU (Remote Terminal Unit). The low quiescent current consumption means that the NetMan remote telemetry control equipment does not place a burden on the existing installation.

FastNet-RTU
The FastNet is a compact RTU designed for use in electricity transmission and distribution networks. Principally for use with distribution automation equipment in the secondary electricity networks, its design also allows it be used as a data concentrator and/or a primary SCADA RTU.

T-Mod Remote I/O Telemetry Module
The Radius T-Mod I/O Telemetry Module is a compact device designed to transfer control and indication data as well as analogue signals from remote sites to a central hub. The T-Mod can be used as a simple mirrored I/O between two points or can be used to connect a large number of slave units to one central master device.

NMS 100 for Remote Control
NMS 100 is an intelligent remote control unit designed to monitor and control from one to nine switches/disconnectors. The unit has advanced features to allow automatic sectionalizing of the HV network under fault conditions and has an option for fault current indication.

Remote Control – RNO Series
At the heart of the NetMan system are a range of digital data Radio Network Outstation (RNO’s). This is an intelligent data radio modem, which communicates with either the NetMan RTU (in order to collect or transmit digital commands), an analogue input unit (which monitors up to 8 analogue input channels) or an external DNP3 device. In built diagnostics allows the user to test the bit error rate (BER) of any radio path, either during commissioning or during maintenance. All of these devices operate through a NetMan-FSS data concentrator fitted with an digital data Radio Network Concentrator (RNC’s). Each RNO data radio has a unique repeating function allowing the user to cover very large/wide geographical areas without any additional infrastructure cost.

Remote Control – RTU-16D
The NetMan system is made up of 2 main building blocks. The RNO data Radio Network Outstations and the RTU-16D digital input/output card. The RTU-16D card is designed to work with the RNO 301 and RNO 401. Each card provides 16 digital inputs and 16 digital outputs. Each digital input consists of a bi-polar opto-isolated connection, with an LED indication to be able to see at a glance the status of the input. Digital outputs are driven through isolating relays, again each output is supported by an LED to determine it’s status.

Local and Remote Control Retrofit
To experience the benefits of the local control achieved by the T20 panel and Radius flexible communication solution you can order a retrofit to boost your current overhead switchgear. The T20 control panel and the radio can be built-in in the existing cabinet. Radius radio gives you the possibility to choose among numerous communication alternatives.
