MOUNTING PLUG-IN MODULES
The controller supports up to 3 plug-in modules, viz.
Output-2 Module
(Relay / SSR or DC Linear),
Output-3 Module
(Relay /
SSR or DC Linear) and
Option Module
(RS485 Serial Port or Digital Input for Auxiliary Setpoint selection). These modules are
either pre-fitted while the controller is shipped from the factory or can be fitted by the user later.
All 3 plug-in modules are provided with female socket that directly fits into the corresponding male plug provided on either
Power-supply PCB or CPU PCB. The
Output-2
and
Option
Modules fit into plugs provided on Power-supply PCB whereas the
Output-3
Module fits into plug provided on the CPU PCB.

Figure 10.5 : Input Jumper Settings
The Input type and the Output-1 type are user configurable and thus require, besides parameter selections,
proper jumper-
settings prior to electrical connections. The jumper settings are provided in the form of Pins & Shorting-Link arrangements on the
CPU PCB towards the rear end as shown in Figure 10.4. The Jumper setting marked A is for Input configuration whereas those
marked B & C are for Output-1 configuration.
INPUT : Jumper Settings
For DC Linear Current Inputs (0-20mA or 4-20mA), short the Pins using Shorting-Link as shown in Figure 10.5 (a). For all other
Input types, keep the Shorting-Link parked leaving the Pins open, as shown in Figure 10.5 (b).
OUTPUT-1 : Jumper Settings
Besides the parameter settings, the Output-1 configuration requires jumper settings marked B & C for different output type
selections as shown in the Table 10.1 below.
