Expansion Modules

The JNIOR logic controller utilizes Plug and Play expansion modules to keep the cost of the core controller low while allowing for the cost-effective addition of more relay outputs and/or analog signals in the future. Expansion modules connect to the JNIOR’s sensor port using a 6 Pin Modular Flat Cable with an RJ-12 Connector. Cable lengths have been tested up to 100 feet with one module, but the number of modules impacts the maximum cable length before powering the module fails. Each Expansion Module works on any JNIOR logic controller model and contains the following key features:

• On-board microprocessor for rapid, effective analog signal sampling
• Automatic recognition of the module by the main JNIOR logic controller
• Flexibility to utilize a mix of modules
• Can be used in addition to the JNIOR temperature sensors
• Web-based configuration via the main JNIOR web page
• Easily integrated into all the JNIOR communication methods
• No separate power supply necessary – all power received via the Sensor Port
• 2-year warranty
