Part Number: SC-9100
Function: DDC Controller
Package: Module type
Manufacturer: Johnson Controls
DDC Controller stands for “Direct Digital Control Controller.” It is a device used in building automation systems (BAS) and HVAC (Heating, Ventilation, and Air Conditioning) systems to regulate and control various building functions digitally.
SC-9100 is a preconfigured, controller, designed for the control of heating, ventilation or air conditioning installations. The SC-9100 is a unique controller with multiple standard applications, which can be chosen from the controller’s memory during installation. Parameters can be adapted to fit the exact requirements. Other application programs may be created on quantity order. The display shows in clear text the inputs, outputs and main control information. The controller is protected to avoid unauthorized use (password). The SC 9100 is a full stand-alone controller, and may be connected to a communication bus as part of a JOHNSON CONTROLS Supervisory System. The room command module SC-9180 may be connected to the SC-9100 to provide remote set point and real time clock. Series SC-9100 Easy DDC Controller and Application Manual Features and Benefits !

Wiring: Before connecting or disconnecting any wires, ensure that all power supplies have been switched off to prevent equipment damage and avoid electrical shock. Separate extra low voltage (safe) wiring from power line voltage wiring. The 24 V supply must be stable and not shared with other switched inductive loads. Software: SC-9100 contains PI modules, ON/OFF, calculations (e.g. set point reset by outside tempera-ture), logic controls (e.g. frost protection, clock) Applications: The SC-9100 applications a […]
