Product Description:

The ERC 112C is an electronic climate controller manufactured by Danfoss as part of the Electronic Climate Controllers series. It manages temperature regulation, defrost cycles, and auxiliary functions in refrigerated cases and compact HVAC systems, acting as a self-contained control point between field sensors and compressors. By integrating input measurement, algorithmic processing, and relay actuation, it maintains consistent cabinet conditions without the overhead of an external PLC.

This controller offers 4 analog inputs that accept thermistors or pressure transducers for multi-zone monitoring. A single status line is catered for through 1 digital input, often linked to door switches or external timers. Equipment such as fans, lights, or solenoid valves can be driven via 4 digital outputs, each presented on an isolated relay contact. Operators view parameters on a Blue backlit display that remains legible in low-light retail environments. Internal timing aligns with mains supplies at 50/60 Hz, allowing identical hardware to be installed worldwide without modification.

Electrical versatility is provided by a supply range that begins at 100 VAC and rises to 240 VAC, so a single SKU functions in regions with differing line voltages and tolerates modest brown-outs. The device weighs only 0.077 kg, minimizing load on thin panel walls and facilitating quick retrofits. Belonging to the Electronic Climate Controllers family ensures shared parameter files and wiring harnesses across Danfoss case-control products, simplifying maintenance inventories while keeping installation footprints small.

Wake Industrial can arrange same-day shipping for orders placed before the daily cutoff. Each ERC 112C is protected by a 1-year warranty that covers functional defects. A free chat tool is available on the website for general questions about type codes or fault indicators.
