Micromod Micro-DCI: 53SL6000 Single Loop Controller - Manual (Page 25)

Figure 2-8. Input Configurations
2.7 2DI/2DO Module
This information applies to only those controllers
with the optional 2DI/2DO module.
2.7.1 2DI/2DO Backplane Installation
Figure 2-9 illustrates the 2DI/2DO module location
on the controller backplane. The 2DI/2DO module
is socket mounted and is secured to the backplane
with two screws. Also shown in Figure 2-9 are the
2DI and 2DO signal plugs that are screw mounted
to the module (the plug mounting screws are not
illustrated). The two plugs are different in size;
therefore, they can not be inadvertently installed in
the wrong sockets and each plug is keyed to pre-
vent inverted insertion into its module socket.

2.7.2 2DI/2DO Signal Wiring
As shown in Figure 2-9 (e.g., INSERT SCREW-
DRIVER), the lug adjusting screws are accessed
on the side of the plug.
Signal input connections for the 2DI four terminal
plug are illustrated in Figure 2-10. The functional
description for DI3 and DI4 is identical to that de-
scribed in Section 2.5.3 for DI1 and DI2.
