Measuring Rain by Using a Signal Conditioner (Computing Unit)

Overview

This describes a rainfall pulse integration that uses an M series computing unit MXT (XJJM.511) free program. The XJJM.511 hardware is a computing unit with 3 isolated inputs and 1 output. There is 1 analog input, 2 digital inputs, and 1 analog output. The rain gauge's unit rainfall pulses are integrated and sent to the analog output (e.g. 1–5 VDC). The output rainfall integral value is 0% for a count of 0, and 100% for a count of 100. When the rainfall integral value reaches 100%, 100% is output for 1 second, and then the integral value returns to 0%. The maximum value of the rain integration can be changed on the VJ77 or other device.

I/O

1st input (X1): Unused
2nd input (X2): Rain gauge pulse signal (DRY contact, 0.5 mm/P)
3rd input (X3): Reset signal (DRY contact, ON=Reset)
1st output (Y1): Integral analog output free program editing

Examples of Programs and Parameters

User Program Editing

User programs can be edited using the VJ77 or other tools.

The VJ77 is a software program for configuring parameters and computing unit programs of the PC-based JUXTA signal conditioners.
