The AS-UNT1126-700 model from Johnson Controls is designed as a unitary (zone) controller. This device features a lightweight design with a weight of just 1.4 lbs, making it convenient for installation. It provides six analog inputs and six binary inputs that operate with 24 Volts AC dry contact requiring a minimum of 10 mA. The controller has two analog outputs, delivering 0-10 VDC at a current of 10 mA. Additionally, it is equipped with six binary outputs, utilizing 24 Volts AC relays rated at 2 Amps per output, with an inrush rating of 13 Amps while maintaining compliance with Class 2 pilot duty regulations.
Operating on a voltage rating between 20 and 30 Volts AC, the AS-UNT1126-700 operates efficiently across a frequency of 50/60 Hz. The current rating indicates an approximate power consumption of 1.67 A, accounting for a typical system total of 40 VA when outputs are included, while the maximum for the controller alone is 7 VA. This unit can operate safely within temperatures as low as -40°C and as high as 60°C, ensuring reliable performance in diverse environments.
For enhanced usability, this controller features quick-connect terminals (in the -700 variant) and screw terminals for N2 communication. It allows for versatile mounting options, including surface mounting or installation on a 35 mm DIN rail, catering to differing installation preferences.
