Dynasonics MFX Series Insertion MagProbe Flow Meter - Manual (Page 18)

Rev. 01/11 -1.16- MFX
General The MFX utilizes ISO-MODs for input and output functions. ISO-
MODs are epoxy encapsulated electronic input/output modules that
are simple to install and replace in the field. See Figure 1.10. All
modules are 2,500 V optically isolated from MFX power and earth
grounds. This eliminates the potential for ground loops and reduces the
chance of severe damage in the event of an electrical surge.
Six ISO-MOD options are available, including: 4-20 mA, dual-relay,
rate pulse, RS232C, RS485, and 200k point data logger. The MFX
supports any of the six ISO-MOD input/output modules. All modules
are field configurable by utilizing the keyboard or ULTRALINK™
interface. Field wiring connections to ISO-MODs are quick and easy
using removable plug-in terminals. Configuration and connection of
the various ISO-MODs are described on the following pages.
To remove an ISO-MOD, remove the two machine screws that
secure the module in place and pull the module straight out of the
enclosure. A 10-pin connection is on the bottom of the module that
mates with the circuit board underneath. Installation of a module is
simply the reverse operation of removal. 4-20 mA modules will
require calibration parameters to be entered if the module is
replaced. See Part 3 of this manual for instructions on entry of
calibration parameters.
