CFM Module
What is the Configurable Flowmeter Module?
This chapter describes the ControlLogix® configurable flowmeter module.
It also describes what you must know and do before using the module.
The ControlLogix CFM module is an intelligent I/O module that performs
high-speed flowmetering for industrial applications. The module is a single-
slot module that interfaces between a Logix controller and external I/O
devices.
The module interfaces with these output types:
•
Magnetic Pickup
•
TTL
•
Preamps
ControlLogix CFM modules mount in a ControlLogix chassis and use a
removable terminal block (RTB) or a Bulletin 1492 interface module cable that
connects to an IFM to connect all field-side wiring.
Before you install and use your module you should have already:
•
installed and grounded a 1756 chassis and power supply.
To install these products, refer to these publications:
-
ControlLogix Power Supply, publication 1756-IN619
- ControlLogix Redundant Power Supply, publication
-

•
ordered and received an RTB or IFM and its components for your
application.
RTBs and IFMs are not included with your module.
