Johnson Controls model RA-1270 is available with the following variations at additional cost. See Table 1 for options.

  • Sensor cable lengths: for client monitor boxes, 10 ft (3.05 m) is standard and 25 ft (7.62 m) is available as an option. For local host monitor boxes, 25 ft (7.62 m) is standard. Remote host monitor boxes do not include sensor cable assemblies.
  • Client data/power cables are available in lengths of 18 in. (457 mm), 32 in. (813 mm), 44 in. (1,118 mm), 50 in. (1,270 mm), 10 ft (3.05 m), and 25 ft (7.62 m) and include factory- terminated phoenix connectors. 50 in. (1,270 mm) is the default length.
    Note: Installations that include a local host and one or more client monitor boxes include one 25 ft (7.62 m) length of data/power cable to connect the local host to the nearest client monitor box.
  • Remote host installation can be up to 500 ft (152 m) away from the client monitor box when 25 ft (7.62 m) sensor cables do not reach the host. The host, unlike the client monitor box, must be located external to the air stream and easily accessible during the calibration process. Selection of the remote host option adds one client monitor box to the airflow measuring station. There are no sensor assemblies connected to a remote host.
  • Remote host feature includes data/power cable length options of 10 ft (3.05 m), 25 ft (7.62 m), and 50 ft (15.2 m). The remote host data/power cable connects the remote host to the nearest client monitor box.
