DIN Rail Bus Connector Kit

 

 

Bus Connector Kit for DIN Rail Bus Connection to Power Model TTBUS-KIT 

 

This kit contains one each of the following terminals  

 

• 

DIN Rail Bus Connector 1005-063 for 17.5mm TT Modules.  

• 

Left Side terminal block, female connector 1005-220.  

• 

Right Side terminal block, male connector 1005-221. 

• 

Two End Stops for 35 mm DIN Rails 1027-222 (not shown). 

 

This module was shipped with the first item included in this kit, DIN Rail Bus 

Connector 1005-063, and this kit offers a spare. Left and right side terminal blocks 

that mate directly to the bus connector are included in this kit. These terminals are 

used to optionally (or redundantly) drive power to Series TT modules via their DIN 

rail bus connector.  This also allows modules to neatly and conveniently share 

connections to Power.  Two end stops 1027-222, used to secure the terminal block 

and module for hazardous location installations.
