 Precise Data Acquisition

Moxa’s ioPAC 5500 RTUs offer 250 Hz-level analog input sampling rate, giving engineers the analog data precision they need to correctly analyze events. In addition, the analog input pre-recording function allows the ioPAC 5500 RTUs to continuously record analog input data before an event trigger point for improved data completeness.

 Sustainable System Reliability

The ioPAC 5500 is designed for data acquisition in any harsh environment. It can operate in temperatures ranging from -40 to 75°C (-30 to 75°C for HSPA models) with UL/cUL Class 1 Division 2, and supports EN 50121-4 for the railway industry, with rail-level surge and ESD protection.

 Easy Data Acquisition

Moxa’s ioPAC 5500 RTU controllers come with Moxa’s patented Active OPC server and DA-Center software. Active OPC server adds a non-polling architecture to the standard OPC protocol, giving users the advantage of push-based communication from Moxa’s controllers to the SCADA systems. DA-Center, on the other hand, provides a standard OPC interface that interacts with Moxa Active OPC Server for real-time data collection.

 Easy to Deploy

Moxa’s ioPAC 5500 RTU controllers are compact and come with two 10/100 Mbps Ethernet ports (two MACs, port-trunking ready), and two 3-in-1 serial ports, making the ioPAC 5500 ideal for cabinets with limited space.

Real-Time Remote Monitoring via Cellular Technology 

In this paper we discuss the technical challenges inherent in remote data acquisition, with special emphasis on applications that involve the monitoring and control of data from extremely distant pipeline, pump, and wayside equipment. We first consider what is involved in deploying a cellular communications system for remote monitoring, and the critical features and functionality required to make this a viable solution.

The following topics are covered:

  • Why Cellular?
  • Dynamic Versus Static IPs
  • Active Data Transmissions
  • Guaranteed Data Integrity
