LH100

Temperature Controller for Piping

The LH100 is a compact, pipe-mounted temperature controller featuring a built-in SSR (up to 7 A) and convenient push-in wire connectors for rapid installation. Equipped with RS-485 communication, a digital input, and an event output as standard, it delivers efficient and centralized control. Versatile mounting allows attachment to both horizontal and vertical piping, as well as DIN rails, while a simple front LED provides clear operational status. Safety-enhanced design includes an internal fuse and relay for protective load interruption.

Features

Space-saving built-in SSR (solid-state relay) supporting up to 7 A
Push-in wire connectors for speedy and secure wiring
RS-485 communication, plus one digital input and one event output, as standard
Flexible installation—pipe (vertical/horizontal) or DIN-rail mounting
Safety circuitry with internal fuse and load isolation relay
Front LED indicators for power, comms, and event status
Optional LH110 variant adds a rotatable setting display for parameter setup
Software-enabled configuration via PC (using USB engineering cable)
Supports Master/Slave configuration via RS-485 for synchronized multi-unit control
Compact and versatile system suitable for tight panel spaces

Applications

Direct temperature control of piping in water or oil heating systems
Compact thermal regulation in factory automation lines
Centralized heating control in modular piping networks
Modular panel-mounted temperature regulation in OEM systems
Upgradable setups requiring local LED feedback and remote configuration
Master/slave configurations in heating jackets or multi-point piping systems
