DX-9100-8004

The DX-9100-8004 model from Johnson Controls is categorized as an extended digital controller. This unit is equipped with a capacity for 8 analog inputs and 8 digital inputs, making it suitable for complex monitoring and control tasks. For output, it offers 2 analog outputs and 6 digital outputs, which can be configured to meet specific operational demands.

The analog inputs can handle a range of 0–10V, 0–20mA, or RTD, allowing flexibility in sensor integration. Similarly, the analog output options include 0–10V or 0–20mA, with a 4mA offset for precise control. Digital outputs can be utilized for functions such as on/off switching, pulse modulation, position adjustment, and duration modification.

Communication with this controller occurs via N2 Bus (RS-485) and XT Bus, enabling robust connections within a control network. Its I/O can be expanded to accommodate up to 64 points using XT or XTM modules, enhancing the versatility of the system. Additionally, the programmable functions support 12 modules dedicated to PID control, logic operations, calculations, and scheduling tasks.

For scheduling, the controller provides 8 independent time schedules, further enhancing its utility in automated systems. User interaction is facilitated through an LED display and keypads designed for straightforward operation. The unit is powered by 24 VAC, and it features both capacitive and lithium battery backup for reliability.

Configuration tools include the GX-9100 software and the SX-9120 module, which streamline setup and customization processes. The DX-9100-8004 also supports peer-to-peer communication, vital for distributed control architectures, thereby ensuring that it can effectively integrate into various operation scenarios.
