Allen-Bradley 1756-IF6CIS ControlLogix Sourcing Current Loop Input Module

Description

The 1756-IF6CIS and 1756-IF6I modules primarily operate the same with a few exceptions, including:

• The 1756-IF6CIS only operates in current mode
• The 1756-IF6CIS offers an isolated power source for each channel that supplies power to external transmitters

The 1756-IF6CIS module offers an internal power source on each channel. The source is current limited to 28mA and allows the module to power a two-wire transmitter directly without the need for an external power supply. The transmitter can then vary the current to the analog input in proportion to the process variable being measured. The inclusion of an internal an on-board current source, saves you the expense of extra power supplies and greatly simplifies the interface wiring to field devices.

In addition to supplying loop power to 2-wire transmitters, the module can also acomodate current loops powered by an external supply and loops using 4-wire transmitters.
