MOUNTING PLUG-IN MODULES
The controller supports Input-2 (DC Linear Voltage) module which is mandatary for measuring Relative Humidity (%RH) Value
and two optional plug-in modules, viz. Output-3 (Relay/SSR) module and Serial Communication module. These modules are
either pre-fitted while the controller is shipped from the factory (if ordered with the basic configuration) or can be fitted by the
user if ordered separately. Both the optional modules have female connector (socket) mounted on them, which fit into the
respective male connector (plug) provided on Power-supply board
Output-3 Module
The Output-3 module provides jumper selectable Relay contacts or SSR drive as output. The Figure 10.4 below shows the
output module and the jumper arrangement.
Figure 10.4
As shown in above Figure, there are 2 jumper arrangements marked A and B. The selection between Relay and SSR requires
both these jumpers A and B to be set appropriately as shown in Table 10.1 below. The double headed arrows show the
adjoining Pins that require shorting using the Link.

The Figure 10.5 below illustrates how to mount the plug-in Output-3 module. Notice the orientation of the controller and a few
identifying components shown in figure to help locate the plug for the module. Ensure that the socket snap-fits into the plug
and the 2 Projections of the module board fit into the 2 Slots provided on the Power-supply board for proper electrical contacts
and secured fitting.
