The T24-GW1 wireless modbus gateway collects serial data from up to 100 separate T24 wireless transmitter modules in a monitoring system and provides an RS232/RS485 interface using either the Modbus RTU protocol or a simple ASCII protocol to allow users to collect the data with PC, PLC or other SCADA data acquisition system for further analysis.  The T24-GW1 wireless gateway module has a range of up to 800 metres.

The T24-GW1 wireless modbus gateway can provide some simple commands to the wireless transmitters.  The T24-GW1 can command the wireless transmitter modules to ‘wake’, ‘sleep’ and ‘stay awake’ if required.

TheT24-GW1 wireless modbus gateway comes housed in an IP67 weatherproof enclosure which is suitable for mounting in both indoor and outdoor environments.

Please note: The T24-GW1 will NOT act as a base station and cannot be used to configure T24 modules. It will support all transmitter modules that deliver a single value in their Data Provider packets. The T24-GW1 does not support the T24-SAf.

The T24 range of wireless telemetry instrumentation works with any of our wide range of transducers and sensors that we offer and can come calibrated as a complete wireless setup.  Please contact our expert sales team using the quick enquiry form on the right, call us on +44 (0) 1189 817339, or send an email to info@appmeas.co.uk and we will be happy to assist you with your enquiry.
