Introduction
Thank you for purchasing an RST-5003 Web Enabled Control Module from APG. We appreciate your
business! Please take a few minutes to familiarize yourself with your RST-5003 and this manual.
The RST-5003 Web Enabled Control Module oers a wide degree of integrated, exible, remote and local
control and monitoring for your system. The RST-5003 can control up to 10 APG Modbus sensors--any
combination of level, pressure, magnetostrictive and ultrasonic--along with one 4-20 mA sensor, and two
input or output relay terminals. All readings are available for control and monitoring via TCP/IP for local
or remote network access. The RST-5003 also had exible power options: it can use either POE or an
independent 12-28 VDC power source.
Reading your label
Every APG controller comes with a label that includes the controller’s model number, part number, and
serial number. The RST-5003 label also indicates the default IP address, subnet mask, and mac address.
Please ensure that the model number on your label matches your order.

Chapter 2: Installation and Removal Procedures and Notes
• Connection Notes
• Up to 10 Modbus sensors can be connected to the RST-5003 in any combination.
• Only one 4-20 mA sensor can be connected to the RST-5003.
• You do not need any tools to install your RST-5003. Please consult each sensor’s user manual for any
sensor installation notes and instructions.
• Tools Needed
• Connect any 4-20 mA sensor, relays, or switched inputs rst.
• Connect RST to Ethernet/network.
• Connect independant 12-28 VDC supply if not using POE.
• Connect and set up one Modbus sensor at a time.
• Electrical Installation
NOTE: For any APG sensor user manual, please visit http://apgsensors.com/support.
IMPORTANT: Each Modbus sensor must be connected to the network individually and
assigned a unique Sensor Number before the next sensor can be added.
IMPORTANT: Multiple Modbus sensors added to the network simultaneously are all
assigned the same Modbus address/sensor number: 1. Sensors MUST be added to the
network individually.
