Pay attention to the use of convenience and space saving,
Relay terminal for 16 point output.
The terminal block is a long and thin type with a width of 135 * Deep 40mm.
It can be easily connected to the common end with the independent contact and short circuit chip.
Terminal units for power supply wiring processing can be extended.
M3.5 can be used with the Y fork type of the compression terminal (terminal width 6.2mm).
Can not use the tool to remove the relay. Relay replacement operation is simple.
