Installation Instructions for Innotech Genesis Systems
Edition 011100 2-3
2-2.1.2. Genesis I Digital Controller. The Genesis I Digital Controller is used only
in Genesis I Systems. The main physical difference between the Genesis I and Genesis II
controllers is that the Genesis I Digital Controller does not contain a display or operator’s
keyboard as does the Genesis II controller. This means that, unlike the Genesis II Digital
Controller, providing access to controls and indicators is not a consideration when installing
the Genesis I Digital Controller. The Genesis I and Genesis II Digital Controllers are
similar in all other respects, including dimensions.
2-2.1.3. Genesis II Mid Points Controller. The GENII MPC Mid Points
Controller module (Figure 2- 3) is a state-of-the-art processing system that performs the
same controller functions as a digital controller. The GEN II MPC can be used in a Genesis
II System as the main controller or as a supporting controller. It is designed for DIN Rail-
mounting inside a control panel. The MPC does not have external controls or indicators.

2-2.2. EXPANSION MODULES. Expansion modules increase the capability of a
controller by allowing more input and output devices to be connected to it. The following
paragraphs describe two classes of expansion modules: Local Expansion Modules and Remote
Expansion Modules.
2-2.2.1. Local Expansion Modules. The term: Local Expansion Module (LEM) is
the collective name applied to the following types of units used to configure the hardware to
the customer’s requirements.
•
Analogue Input Module (AIM)
•
Digital Input Module (DIM)
•
Digital Output Module (DOM)
Up to eight LEMs can be included in the system in any combination. They are designed for
easy mounting on standard DIN Rails. A typical LEM is shown in Figure 2-4. The LEM
shown in Figure 2-4 is a Digital Input Module; however the three types of LEM are similar
in appearance and are identical in their dimensions.
There are restrictions on how far apart the LEMs can be from each other and from the
controller; these requirements are explained in Paragraph 2-3.
