Database? More like databeast

• With tons of nonvolatile memory, the RC‑FLEXair has enough space to handle the most challenging applications now and in the future. It automatically logs all input, output, value, calendar, loop, and schedule objects, which can each store more than 2,000 records. That’s enough for over 1 million data points! It also has space for 64 control programs, each large enough to run advanced energy sequencing, integrated fault detection and diagnostics, and much more.

Ultimate flexibility

• With many available models and options, the RC‑FLEXair is suited to a wide variety of projects. You can order models with one or three universal inputs and up to six outputs with a mix of universal or solid-state relay outputs. Better still, the RC-FLEXair can communicate with up to eight Reliable Controls SMART‑Net™ devices and expand the controller’s capability without consuming inputs or outputs. You can connect temperature, humidity, gas detection, or occupancy sensors; a SMART‑Sensor™ EnOcean Accesspoint; or even the SMART‑Net Relay with up to five heavy-duty mechanical relays.

Ideal for terminal control

• The RC‑FLEXair features an optional precision-airflow sensor and a brushless DC damper actuator, making it ideal for many types of terminal control applications. The pressure sensor ports are highly resilient and made from die-cast aluminum; combined with the aluminum enclosure and steel baseplate, this controller is rugged and built to last.

Better by design

• RC-FLEX Ethernet models are equipped with a versatile USB application port that provides convenient access to a technician today and extended capabilities tomorrow. You can power the controller via USB from a laptop to permit configuration, firmware updates, programming, and graphics creation. You can also use the USB port to access the entire BACnet network.
• All input, output, and communication ports are hardware‑protected against transient surges and spikes, which hardens the controller against field-wiring mistakes and improves resilience.

Network resilience

• To improve Ethernet network resilience and safeguard against common failures, all RC-FLEX family controllers come standard with Copper Switch™ technology and support for Rapid Spanning Tree Protocol (RSTP). Copper Switch ensures that data can still pass through if a controller loses power, maintaining uptime. RSTP lets you connect controllers in a ring topology, which provides inherent redundancy with a duplicate network path; controllers can maintain communications even if one part of the ring is severed.

Sustainable hardware

• Reliable Controls rigorously engineers its products to minimize their impact on the environment and provide years of dependable, high-performance service. The RC‑FLEXair is manufactured in an ISO 9001 and 14001‑certified facility and features an industry‑recognized 5‑year warranty. Made from highly recyclable materials, it also complies with RoHS 3, WEEE, and R2 directives to ensure easy, clean disposal at the end of its useful life.
