MODEL 5081-A

1.10 ORDERING INFORMATION

The Model 5081-A Transmitter is intended for the determination of oxygen (ppm and ppb level), free chlorine,
total chlorine, and ozone. For free chlorine measurements, which often require continuous pH correction, a sec-
ond input for a pH sensor is available. The transmitter is housed in a weatherproof, corrosion-resistant enclo-
sure. A hand-held infrared remote controller is required to configure and calibrate the transmitter.

1.11 ACCESSORIES

POWER SUPPLy: Use the Model 515 Power Supply to provide dc loop power to the transmitter. The Model 515
provides two isolated sources at 24Vdc and 200 mA each. For more information refer to product data sheet
71-515.
ALARM MODULE: The Model 230A alarm Module receives the 4-20 mA signal from the 5081-A transmitter and
activates two alarm relays. High/high, low/low, and high/low are available. Hysteresis (deadband) is also
adjustable. For more information, refer to product data sheet 71-230A.
HART COMMUNICATOR: The 275, 375, or 475 HART communicator allows the user to view measurement val-
ues as well as to program and configure the transmitter. The 275, 375, or 475 attaches to any wiring termi-
nal across the output loop. A minimum 250 W load must be between the power supply and transmitter. Order
the communicator from Rosemount Measurement. Call (800) 999-9307.
