Model 4046 SDI Sensor

Instruction Manual 60-0004046-00

1.0 INTRODUCTION

1.1. General Description:

The model 4046 SDI Sensor provides an interface to convert inputs from two

(2) analog sensors and one (1) tipping bucket to an SDI serial data interface.

The 4046 also provides internal measurements of battery voltage and

ambient temperature.

1.2. Specifications:

Weight 1.9 oz.

Operating Temperature -30-60Degrees Centigrade

Power requirements 12 VDC

<200 uA during sleep

<1 A for sensor power

Mounting: Din Rail

Connections: Screw Terminal

Wire Size #24-#14 AWG

Inputs: Gnd, + 12VDC, (2) Analog 0- 5VDC

Tipping Bucket (contact closure to ground

Communication: SDI -12 (version1.1 compliant)

Sensor Power: 12VDC or 5.00VDC (jumper selectable)

2.0 OPERATION

The 4046 responds to all basic SDI commands. The sensor power is switched

on after successfully decoding a “Start Measurement” command and switched off at

the completion of the measurement. The duration (sensor warm-up time is

programmable using SDI commands. The 4046 will go into low power sleep state

when it is not being polled. User values for Slope (multiplier) and Offset (adder) are

programmable for both analog channels and tipping bucket. The tipping accumulator

can be set to zero by SDI command.
