MINio
MINio is a distributed I/O module capable of interfacing a large variety of analog and digital input or output loads. When combined with Novar's OpusTM Executive Controllers, MINio delivers the most flexible, efficient and reliable I/O solution for monitoring and controlling refrigeration, HVAC and other building equipment.

Refrigeration Rack Input Module
This module collects and transmits much of the refrigeration rack status information that determines the control activity of an Opus Refrigeration System. It provides 37 analog and digital input connections for dry contact closures and temperature, pressure and current sensors. Inputs that can be connected to the Rack Input Module include compressor current, compressor oil protection switch, compressor discharge temperature, suction pressure and other digital inputs, such as the receiver float switch.

RCC.521
The rcc.521 is a multi-function BACnet field controller providing state-of-the-art Electronic Expansion Valve (EEV) control for refrigerated display cases, cold rooms and walk-in freezers. It can also be used with Electronic Evaporator Pressure Regulator (EEPR) valves for enhanced circuit temperature control and improved cost savings in distributed systems.

Refrigerant Leak Detection
Novar Refrigerant Leak Detection Panel Kits deliver all the components necessary to monitor walk-in cooler/freezer refrigerant gas levels in an easy to install package perfect for supermarkets, convenience stores, restaurants or other business where local building codes require safeguards against refrigerant gas leaks.
