RGS3000

Summary

Product identification

The RGS3000 is a universal controller for automatic monitoring and control of reverse osmosis plants. It supports several operational stages: "Stand by", "Production", "Rinse after production", "Rinse during production", "Rinse during standby", "Maintenance", and "Regeneration".

Ordering Information

• RGS3x00: 4 digital inputs, 3 relay outputs, 1 conductivity meter, 1 temperature meter, and SD Card functions.
• RGS3x01: 5 digital inputs, 5 relay outputs, 1 conductivity meter, 1 temperature meter, and SD Card functions.
• RGS3x12: 5 digital inputs, 5 relay outputs, 1 conductivity meter, 1 temperature meter, SD Card functions, Ethernet (internet/email), and RS485.

The 'x' in the model number denotes the power supply configuration:

• 0: 24 VAC input / 24 VAC output
• 1: 115 VAC input / 115 VAC output
• 2: 230 VAC input / 230 VAC output
• 3: 115 VAC input / 24 VAC output
• 4: 230 VAC input / 24 VAC output
• 5: 240 VAC input / 24 VAC output

An example configuration is RGS3212, indicating a 230 VAC input/output, with SD Card, 5 digital inputs, 5 relay outputs, conductivity and temperature meters, Ethernet, and RS485.
