Temperature Controller for Piping

LH100
The LH100 series is a downsized temperature
controller for piping with built-in SSR, which enable
to shorten installation time with push-in wire
connectors. Standard provision of RS485 communications, Digital Inputs and Event Outputs enable
to realize cost-effective temperature control.

■FEATURES●Downsized controller with built-in SSR (Max 7A)

By connecting with heater, enable to control temperature in aspace-saving and less wiring.

●Standard provision of digital communications and event
functions
The LH100 series is having RS485 communications, digital
inputs and event outputs as standard provision, which realize
centralized control and monitoring with graphic panels.

●Detachable push-in wire connectors

LH100

LH110

(without setting display)(with setting display)

After making the wiring in advance, it supports one-timeconnection for enabling you to reduce wiring time at the site.

●Designing for safety

The fuse* and relay are built in the controller, and the highcurrent when the load is short-circuited and the load power
supply when the equipment is abnormal are cut off.

■MODELS

Unable to replace the fuse outside factory.

LH1●Various mounting□□NN
Setting display unit
0：None1：Included

Can be mounted to vertical pipes and horizontal pipes fromvarious directions. In addition, since the controller can bedirectly mounted to the DIN rail, it can also be used for control
other than piping temperature.

Additional functions
0：None1：Moisture-proofing*1●Easy-to-use setting display (LH110)*

You can setup and check parameters directly with the controller. The setting display can be installed in either vertical or
horizontal orientation, and is designed to be easy to see andoperate.

1 Not applicable with CE/UKCA marking and UL certification●Indicates operation status with front LED (LH100)

The front LED of the controller notifies you of the startup status,communications, event outputs, etc. Parameter setup / confirmation is possible from communications or dedicated software
package.

●Dedicated software package(can be downloaded at our web site)
One-time parameter setup can be made with software package
by connecting the controller and the PC with USB engineeringcable (sold separately). USB bus powered.

●International safety standards
Conform to CE, UKCA and cUL1PSE-821
