Spade Lug Recommendation
The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and
output terminals of the MicroLogix 1200 controller are designed for the
following spade lugs. The terminals will accept a 6.35mm (0.25 in.) wide spade
(standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.
When using spade lugs, use a small, flat-blade screwdriver to pry the finger-safe
cover from the terminal blocks. Then loosen the terminal screw.
Note:
If you wire the terminal block with the finger-safe cover removed, you
may not be able to put it back on the terminal block if the wires are in
the way.
Surge Suppression
ATTENTION: Inductive load devices such as motor starters and
solenoids require the use of some type of surge suppression to
!
protect the controller output. Switching inductive loads without
surge suppression can significantly reduce the life of relay contacts
or damage transistor outputs. By using suppression, you also reduce
the effects of voltage transients caused by interrupting the current to
that inductive device, and prevent electrical noise from radiating
into system wiring.
