Johnson Controls IFC-1010 Wiring Manual

Johnson Controls, Inc. SLC Wiring Manual — P/N 51870:G 04/23/2009 17
Section 2: Wiring Requirements
2.1 Recommended SLC Wiring
• Twisted-unshielded pair is recommended for IFC-320, IFC2-640, IFC-640, IFC2-3030,
IFC-3030, LCM-320, LEM-320, JLIB-200A, and JLIB-400;
Maximum resistance is 50 ohms per branch. See Table 2.1.
• Twisted-shielded pair: IFC-200, IFC-300/400, JLIB-200
Maximum resistance 40 ohms per branch. See Table 2.2.
To maximize distance on the SLC loop, use the recommended type of wire. Using other wiring
types makes the SLC circuit more susceptible to electrical interference and thus reduces its
maximum loop length.
