Figure 2-2. Mounting Multiple Units
The CN9000A operates on either 115VAC ±15%, 50/60 Hz (std)
or 230VAC ±15%, 50/60 Hz (selectable by changing internal
jumpers-discussed in Section 7). The CN9000A outputs feature
either the standard mechanical relay or the optional non-isolated
5VDC Solid State Driver pulse output (designed for operating an
external DC SSR such as an OMEGA SSR240DC45). Three other
optional outputs are available using a plug-in replacement
combination socket. These outputs are a 1A Triac SSR, 0 to
10VDC, or a 4 to 20 mA DC output. They are described in
Table 1-2.
Figure 2-3 shows the rear view of the controller and designates
which signals connect to the terminals. The chart directly following
Figure 2-3 details the actual connections.
NOTE
When mounting multiple units
allow 3-1/2 inches from center to
center of the unit in the vertical
direction to allow for mounting
bracket and wiring, and 2 inches
in the horizontal direction for heat
dissipation.
