*3-9950.092*

The plug-in modules may be installed either before

or after the base unit is installed in the customer’s

application.

• Always disconnect power from the 9950 Before

adding or Removing any modules.

• Modules can be installed in either slot.

• Refer to 9950 Manual for set up and programming.

Module Installation

1. Remove power from the 9950. Carefully align pins

and connectors (do not bend connecting pins) and

push module rmly into place.

The 9950 Transmitter o󰀨ers the following module options. 3-9950.394-1 is a Single Channel Direct Conductivity/

Resistivity Module, 3-9950.394-2 Dual Channel Direct Conductivity Module, 3-9950.395-M Modbus Module, and

a 3-9950.398-2 Dual Channel 4 to 20 mA Current Loop Output Module.

English

Module Removal

1. Ensure power is disconnected from the 9950.

2. Unplug connectors and squeeze the two retaining

tabs while pulling module out of 9950.

Avoid Electrostatic Discharge (ESD):

●Minimize handling of module to reduce the

possibility of damage due to ESD.

●Handle module by the edges. Never touch

any exposed circuitry or contacts.

●Wear an anti-static wristband or stand

on an anti-static mat, or keep one hand

touching a properly grounded pipe or other

properly grounded piece of metal when

handling module.

CAUTION:

Exercise care when installing or removing module.

Do not bend connecting pins.
