Honeywell 51452810-501 Auxiliary Output/Digital Input Communication Card

The Honeywell 51452810-501 is a combo card specifically intended for Honeywell UDC (Universal Digital Controller) series equipment. An extra electrical output channel called Auxiliary Output can be set to operate a variety of external devices. Consider a light being controlled by a switch. Similar behaviour is shown by this output channel, but inside the UDC system. The UDC can receive digital signals from external sensors or switches thanks to its digital input feature. Consider a computer receiving a signal from a button. Similar behaviour is shown by the digital input, but inside the UDC system. These features are all combined into one card, which makes system integration easier and eliminates the need for additional modules. The UDC2500 and UDC3200 variants are particularly intended to work with the Honeywell 51452810-501.
