TM32纯数字双工无线通讯电台

专为工厂自动化和SCADA系统设计的无线通讯电台

 

优点:

  • 高性能 - Data rates up to 9600 baud with low latency transparent and packet
    switched operation options tailored for industrial monitoring and control applications.
  • 多通道 -Fully synthesized radio transceiver allows operation on virtually
    all channels in the supported bands.
  • 高可靠性 - Radio transceiver designed specifically for high-speed data applications with 100% duty cycle requirements. Complete diagnostics provide real-time radio link performance for system tuning and monitoring.
  • 超薄防水外壳 - Compact design facilitates installation in space limited
    locations. Watertight construction allows operation in difficult environmental conditions without an external NEMA enclosure.

The TM32 radio modem family incorporates state-of-the-art wireless technology designed specifically for the needs of plant automation and SCADA applications. The TM32 offers a variety of configurations allowing the selection of capabilities to match the requirements of most applications. From moderate speed point-to-point to high speed point-tomultipoint network applications, the TM32 is capable of providing reliable and robust data communication.

High-speed RF communication with excellent range requires a radio transceiver that is optimized specifically for data. The TM32 boasts a built-in transceiver that provides an extremely flat modulation response and excellent low-power sensitivity. The TM32 is capable of operating all channels across a 20 MHz bandwidth. Frequencies can be factory or field programmed and changed on-the-fly. A variety of models are supported, allowing operation in both commercial and military UHF or VHF bands. Easy to use configuration, monitoring, and setup software facilitates installation and monitoring of the data link.

The TM32 is designed for use in the harsh environments often encountered in remote monitoring and control applications. The watertight enclosure allows the TM32 to be mounted in exposed areas which would otherwise require additional protection. The rugged aluminum extruded enclosure provides convenient mounting flanges, allowing the unit to be easily mounted in space limited areas.

Pacific Crest Corporation stands behind its products with a one-year parts and labor warranty on all equipment. Extended warranty protection is available for expedited repair/replacement service.
