ELECTRICAL WIRING FOR THE 8045 FLOW TRANSMITTER

3.4.1 18-36 VDC without relays
Remove the cover via the screws on the front display and pull the cable through the
cable gland and wire according to one of the pin assignment diagrams below.
The electronics within the 8045 allows a PLC with a sourcing or sinking 4-20 mA entry
to be connected. Position A (Fig 3.3) provides a sourcing configuration and Position B
(Fig 3.4) a sinking configuration.
On a version with a stainless steel sensor, seal the unused cable gland
using the supplied obstructor to ensure the tightness of the transmitter.
Unscrew the cable gland nut, insert the obstructor and screw the nut back
on the cable gland.
