Wireless gateways gain secure options
The Elpro 105U range of wireless gateways and I/O modules for applications in industrial plant, can now offer improved security for industrial users.
Fast-recovery switch keeps industrial Ethernet up
The OnTime R-208 Ethernet switch enables high-reliability, fast-recovery, redundant ring industrial Ethernet installations, particularly in critical applications.
The units are preconfigured and therefore can be installed without the requirement for a laptop or programming tools.
Simply by pressing a button on the receiver unit it is possible to create a wireless I/O link.
Suitable for a broad range of applications, especially within the utility industries, the range provides a cost-effective solution for remote monitoring and can be used in more complex networks as signal transmitters or receivers.
The RM-105L features two digital/pulse inputs, an analogue input and a thermocouple.
Set point functions are available on the analogue and thermocouple inputs.
The RM-105L can connect to different data buses including Modbus, Ethernet and Profibus via the 105-G Gateway radios.
The RM-105L uses the 869.4MHz frequency range and is capable of transmitting data over a distance of 5km, with line of sight and 500m in obstructed industrial environments.
869MHz radios are not only extremely reliable, but they are also very secure as they cannot be easily monitored by standard laptops and PDAs.
However the RM-105L offers the additional security of military grade 128bit AES encryption for the data transfer.
The units themselves are extremely reliable and Westermo offers a conditional lifetime warranty.
They can be used in operating temperatures of - 40 to +60 C and in humidity of 99%.
A built-in battery management circuit protects against an uncertain external power supply.
The RM-105L is extremely easy to use with a RS232 RJ45 port available for configuration and diagnostics.
Free configuration and diagnostics software can be run either with a direct connection or over the radio.
Powerful diagnostic tools such as signal strength indication (on the front of the receiver) and exception reporting communications enable fast, highly efficient wireless networks.
