Pipe temperature controller LH
LH Series (Japan Only)

The LH100/LH110 piping temperature controller is a regulator with a built-in SSR in a slim body.

Controller with built-in SSR suitable for piping temperature control

It uses a push-in connector that significantly reduces installation time. It also comes standard with RS-485 communication, digital input, and event output, providing cost-effective temperature control. The LH700 EtherCAT converter for LH is a converter that enables EtherCAT compatibility when combined with the LH100/LH110. The LH700 has passed conformance testing at an official certification test center recognized by ETG (EtherCAT Technology Group), an international organization that promotes EtherCAT technology development.

  • By connecting the LH100/LH110 and a heater, temperature control can be achieved with less space and less wiring.
    Can be used for various control other than pipe temperature
  • Uses a removable push-in connector
    Wiring can be connected in advance and then installed all at once, reducing on-site wiring labor and work time.
  • Safe design
    The unit has built-in fuse and relays
  • Compatible with EtherCAT
