T24-VA & T24-IA Wireless Telemetry Voltage & Current Input Acquisition Module

Features :

  • 2 way radio system for data integrity
  • Very low power consumption for long battery life
  • Very small size
  • Worldwide licence exempt 2.4 GHz radio
  • Option of hand held remote display or PC interface for data capture
  • Remote power on/off (sleep/wake)
  • 120 metre (400 feet) range maximum
  • Simple configuration and calibrated via PC using base station with Telemetry Toolkit software

The T24-VA & IA are high performance voltage (0-10V) and
current (0-21 mA - calibrated to a 4-20mA range) to radio telemetry converter modules, offering precision measurement with high performance two-way telemetry. Usable around the globe on licence-free 2.4GHz frequency, the T24 range avoids local radio interference to ensure data integrity and security. For use in any measuring applications, from torque to weight, vibration to flow, the T24 offers users a complete solution to your measurement requirements.

The modules form part of a simple measurement system that offers the opportunity to collect measurements from a variety of sources, enabling accurate and immediate data collection without the requirement for extensive and labour intensive cabling operations.

Transmitting from a analogue module on 2.4 GHz to a variety of receivers including a user friendly simple 2 button handheld T24-HS which captures this data and displays it providing a line of sight communication range of typically 120 metres. The T24-HS also performs the function of waking the T24-VA when it is turned on and sending it to deep sleep module when it is turned off.

The wide temperature operating range and the robust technology ensures that the module is not susceptible to harsh physical or electrical environments. Options include internal or external antenna and a growing range of interface modules.

The licence-free 2.4GHz radio provides a line-of-sight communication range of 120 metres (400 feet), extendable by the use of a repeater. The use of the latest DSSS radio technology minimises local radio interference and ensures data integrity and security.

The wide operating temperature range and the robust technology ensures that the module is not susceptible to harsh physical or electrical environments.

LCM Systems can supply the T24 products integrated into a complete system, to meet a variety of different application requirements. Please contact LCM’s technical department to discuss your wireless telemetry requirements.
