Safety Precautions 

Before using the terminal board, please pay much attention to the following: 

 

This terminal board is used for extending output ports. Do not touch any 

internal circuit or components when you power up the terminal board. 

 

Internal circuit of the terminal board consists of CMOS IC that can be destroyed 

by static electricity. Therefore, do not touch any circuit board before you take 

any preventive actions. 

 

The terminal board is a type of fine instruments. Do not discharge any 

components by yourself. 

 

Make sure surrounding environment is safe and clean, to avoid any possible 

damage from iron dust, wire, water, corrosive gas, or corrosive liquid. 

 

Ambient temperature: -40°C~85°C; Ambient humidity: 0%~90%, no freezing 
and condensation. 

 

The terminal board must be safely grounded, to avoid thunder shock or 
electrical leak. 

 

Space of over 50mm in each side must be secured to ensure good ventilation or 
heat dissipation. Recommended operating temperature: 0°C~55°C. 

 

Rated power for the terminal board should be within range of 24V±10%. Use a 

power regulator in case of instable power supply. 

 

Before connecting or disconnecting with the terminal board, make sure the 

power is off, to avoid electrical shock to the personnel or damage to the 

terminal board.
