Table 3-2. MICRO 84 Specifications
The
MICRO 84 controller (Model M84A) is contained within a rugged metal
housing that is designed to screw mount into a standard 8” deep NEMA
rack. The controller can also be screw mounted onto a wood mounting
panel.
Located on the housing front is a five screw terminal strip and two
indicating lights. The terminal strip is used to co.nnect external AC power
to the MICRO 84 system. The upper indicating light, (POWER), is
illuminated when external AC power is applied to the power supply. The
lower indicating light, (RUN), is on when the processor is solving the logic
networks. Refer to Figure 3-3.
