DELTANET R7515A/B, RP7515A/B, R7516B MICROCEL
™
 CONTROLLERS 
   The R7515B and R7516B have a microbridge airflow 
sensor but not the base unit board assembly, and are 
used for remote airflow measurement. 
   Cases are in three sizes as follows: 
—   The small case (Fig. 2) accommodates a 
MicroCel with base board only or a base board 
and one input board. 
—   The standard case (Fig. 3) accommodates a 
MicroCel with a base board, one input board, and 
one output board. 
—   The large case (Fig. 4) accommodates a 
MicroCel with a base board, two input boards, 
and one output board. 
INSTALLATION 
Mount the MicroCel in a location that allows clearance for 
cover removal, wiring, and servicing. See Figures 2, 3, and 4 
for dimensions and other details. 
CAUTION  
For MicroCels with integral pneumatic transducers, 
mount the MicroCel in a vertical position so that the 
transducers will be oriented toward the bottom of the 
case and below the MicroCel PC boards. This position 
prevents damage from condensation possible from 
main air.
