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.
OUTPUT-2 & OUTPUT-3 : Modules and Jumper Settings
The
Output-2
and
Output-3
Modules come in three versions, viz., Relay / SSR, DC Linear Voltage and DC Linear Current. The
two modules are identical and, thus, can be fitted interchangeably in Output-2 or Output-3 positions.
Relay / SSR Module
This module can be configured for either Relay or SSR output through proper jumper selection. Two jumper settings A and B,
as shown in Figure 10.3 and Table 10.1, are required for Relay or SSR selection.
