Delta IA DTB Temperature Controllers
Delta IA DTB Temperature Controllers offer linear voltage and dual-loop control outputs in addition to relay, voltage pulse, and current outputs. These advanced models execute heating and cooling controls simultaneously in central air-conditioning and heating systems, ensuring that target temperatures are quickly reached. The DTB units feature a built-in RS-485 communication interface with Modbus communication protocol support, Celsius or Fahrenheit temperature display, and two key lock functions. A programmable logic control (PLC) function enables users to set up to 64 groups of temperature and control times. Delta IA DTB Temperature Controllers comply with international installation dimensions and include CE and UL international safety approvals.
