To meet the increasing complexity of temperature control applications, Delta introduces the Multi-channel Modular Temperature Controller DTM Series. The DTM Series consists of a host, measurement modules, I/O extension modules, and extension cassettes. A fully extended DTM group consists of a host plus 7 measurement modules and 8 I/O extension modules for up to 64 points of temperature control. Several DTM groups can even be connected via RS-485 or Ethernet for temperature control of up to 1,000 points or more.
