MSI-EM-IO84NP input/output expansion module

3.10.1 Description

The MSI-EM-IO84NP module is an input/output expansion with 4 non-secure inputs, 4 non-secure outputs
and 4 non-secure input/output combinations whose function is configured using the MSI.designer software.
The MSI-EM-IO84NP module offers the following functions:
• Monitoring of connected devices and sensors
For further information: Connecting devices [chapter 4]
• Forwarding of input information to the controller module
• Receipt of control signals from the controller module and corresponding switching of outputs
The MSI-EM-IO84NP module cannot be operated alone; it always requires an MSI 4xx controller module
(see "MSI.designer" programming software).
It is possible to use multiple MSI-EM-IO84NP modules simultaneously (see System setup [chapter 3.2]).
The voltage of the internal logic is supplied via the system connector and the internal safety bus. The
voltage of the Y1–Y4 and IY5–IY8 outputs of the MSI-EM-IO84NP must be supplied directly via A1/A2 at
the respective module.
Refresh rate
The LEDs of the I1–I4 inputs and the Y1–Y4 outputs or the inputs/outputs IY5-IY8 combination show the
state with a refresh rate of approx. 4 ms.
Restricted selection of inputs
Only the single-channel inputs are available to be selected in the configuration for the MSI-EM-IO84NP ex-
pansion module, for example:
