Oldham MX 43 User Manual

5 – Digital Modules
29
C –Logic input connectors
Each of these 16 inputs can be connected to a voltage-free contact as per
Figure 39. Input status is transmitted by the digital line to the MX 43. There is
no alarm when the contact is closed.
Connection
Refer to Chapter 6, on page 33.
Configuration
Configured via the COM 43 application.
8-Analog Input Module
Function
This digital module enables the
monitoring of 8 analog (4-20 mA or
Wheatstone bridge) inputs.
