. . . . . Johnson Controls YK-SCCPNL-0 Sc-Eq Communication Card With Enclosure
The SC-EQUIP (SC-EQ) Communication Card supersedes the E-Link Gateway and provides BAS network connectivity for Johnson Controls® and YORK® mechanical equipment, such as chillers and rooftop units. It is designed with four active serial ports: The J12 BAS (RS-485) port, the J7 Equipment (RS-232) port, the J8 Equipment (RS-485) port, and the J11 CS port, which allows equipment data to be sent to the Johnson Controls Remote Operation Center for remote chiller monitoring and diagnostics.
To simplify the installation and setup, the SC-EQ Comm Card automatically determines the BAS protocol, Baud rate, and the model of the connected chiller or rooftop unit. The only user setting is the MAC address for the SC-EQ on the BAS network. Several SC-EQ Comm Card models are available for connection to various types of input voltage and equipment. For chillers using the OptiView™ 02430 or 03630 microboards, the SC-EQ Comm Card consists of a single circuit board attached to four studs inside the Micro Panel, using the accessory mounting kit. The microboard supplies 12 VDC input power, eliminating the need for an external power supply. The SC-EQ plug J10-COM needs a ground wire to ground the lug on the panel.
For screw compressor chillers using the 02478 or 03478 microboards, the SC-EQ Comm Card is installed inside the Micro Panel, using the accessory mounting kit. The microboard supplies 12 VDC input power, eliminating the need for an external power supply.
For scroll compressor chillers using the 02050 or 02550 microboards, the SC-EQ Comm Card is installed inside the Micro Panel and requires an additional transformer to supply power to the SC-EQ Comm Card. The transformer is included in the SC-EQ Scroll Chiller Installation Kit.
For other types of chillers, the SC-EQ Comm Card is packaged in its own enclosure. In addition to the SCEQ circuit board, a transformer is included inside the enclosure that converts a 120 VAC or 240 VAC input to 24 VAC power.. Johnson Controls. Johnson Controls. YK-SCCPNL-0.
