Series Information

TX Series

LCD Display PID Temperature Controllers

The Autonics TX series temperature controllers feature easy-to-read LCD displays with large, white PV characters. The 11-segment displays used for PV and SV are useful for displaying various alphanumeric characters and provide improved legibility. The temperature controllers also feature 50 ms high-speed sampling cycle and ±0.3% display accuracy. The space-saving design with 45 mm depth allows easy installation in limited spaces (DIN 48 x 48 mm models). The TX series can be configured and monitored on PCs via USB or RS485 communication, and are available in diverse sizes for flexible installation in various environments.

TX Series main features

  • 50ms high-speed sampling rate and ±0.3% display accuracy
  • Large LCD display with easy-to-read white PV characters
  • Switch between current output and SSR drive output
  • SSR drive output (SSRP function) control options: ON/OFF control, cycle control, phase control
  • Communication output model available: RS485 (Modbus RTU)
  • Parameter configuration via PC (RS485 communication): DAQMaster software included (comprehensive device management software)
  • Compact, space-saving design with 45 mm depth: 30% rear-length size reduction compared to similar-sized (48×48 mm) models from Autonics
