BTU-4D


The BTU-4D Burk Digital Temperature Unit connects up to four digital temperature sensors to an ARC Solo remote control or to a Plus-X input device in an ARC Plus system. Sensor cables up to 1000 feet long are supported without measurement degradation. The unit also provides a low voltage output sample that tracks linearly with the AC line voltage.

Each temperature output supplies 10mV per degree Fahrenheit or Celsius, based on a jumper setting on the BTU-4D/BTU-4D-I.

The BTU-4D/BTU-4D-I  is supplied with:

  • One 120 V AC power adapter for BTU-4D or a 220V AC power adapter for BTU-4D-I  
  • One TEMP-OUTDOOR sensor for either Fahrenheit or Celsius temperature measurement 
  • One 6‐terminal Phoenix-style plug for connection to monitoring equipment

TEMP-INDOOR Sensor

Part #: TEMP-INDOOR

The TEMP-INDOOR Sensor is a general-purpose, digital, indoor temperature sensor tailored for monitoring ambient temperatures within a room or in an equipment rack. Temperature accuracy: ±0.5° C from -10° C to 85° C. Cables are not supplied with this sensor — order 25’ RJ-12 cable, part number SENSOR CABLE.

TEMP-WALLMOUNT Sensor

Part #: TEMP-WALLMOUNT

The TEMP-WALLMOUNT Sensor is housed in a 2 5/8” x 5” enclosure with air vents to facilitate sensing of the environment. Temperature accuracy: ±0.5° C from -10° C to 85° C. A 14’ cable is provided with an RJ-12 connector on one end. The TEMP-INDOOR has a large, easy to connect barrier strip that accommodates flat or Phillips type screwdrivers

TEMP-OUTDOOR Sensor

Part #: TEMP-OUTDOOR

The TEMP-OUTDOOR digital outdoor temperature sensor is included with the BTU‐4D/BTU-4D-I systems, and is intended for general purpose monitoring of equipment or ambient temperatures. Temperature accuracy: ±0.5° C from -10° C to 85° C. The TEMP-OUTDOOR sensor is attached to 25’ of cable with an RJ-12 connector on the end. The sensor has a mounting ring and gasket to accommodate #6 or #8 hardware. The sensing elements are sealed for added protection from dirt and moisture.

TEMP-STACK Sensor

Part #: TEMP-STACK

The TEMP-STACK Sensor is a digital stack temperature sensor designed for sensing heat within the air ducting of your equipment. Temperature accuracy: ±0.5° C from -10° C to 85° C. The TEMP-STACK Sensor is attached to 25’ of cable with an RJ-12 connector. The sensor is mounted in the tip of a 3/8” diameter chrome tube. The supplied mounting hardware consists of a base and a compression fitting to allow the sensor to be secured at variable depths. This allows the installer to locate the sensor up to 9 1/2” from the equipment wall, well within the airflow being monitored.
