Chapter 2 __________________________________________________________ Product Overview Transient Protection Devices Each sensor input in the logger has a varistor (VDR) protection against induced transients. The maintenance terminal I/O ports have transzorb diodes in their inputs. In case of long signal cables, additional transient protectors can be installed on the DIN rail. These surge protectors consist of a combination of VDR, transzorb diodes, and coils, thus providing excellent protection.
User's Guide ______________________________________________________________________ Communication Modules RS-232 Module The RS-232 communication module is unisolated, providing either a double serial channel without handshaking (dual RS-232 module) or a single RS-232 with handshaking (single RS-232 module). The power consumption is less than 15 mA when communicating, less than 5 mA at standby.
Chapter 2 __________________________________________________________ Product Overview The RS-485 isolated communication module provides a 2-wire or 4wire RS-485-communication link between two devices with a similar interface. This module is used, for example, for connecting displays and terminals to the data logger when the distance is longer than 15 meters. The maximum distance for the isolated RS-485 module is approximately 1500 meters at full speed. The module must be configured before use.
User's Guide ______________________________________________________________________ The SDI-12 channel has its own connecting point on the board. It does not use channel A or B for the communication. SDI-12 is galvanically connected to the host board's GND potential. There is a later version of this module, DSI486-B, that widens the operating range and usable RS-485 line speed.
Chapter 2 __________________________________________________________ Product Overview Ethernet Communication Module DSE101 Figure 12 1004-122 Ethernet Communication Module DSE101 Ethernet Communication Module DSE101 is a single, compact, printed circuit board. It provides a 10Base-T Ethernet interface for the QML logger, thus allowing the logger to be accessed, for instance, directly from a LAN environment.
User's Guide ______________________________________________________________________ Data Collection Software The QML logger works based on what is known as a setup. A setup is a set of parameters that tells the logger what to measure, log, calculate, and report. Measured data is stored in the daily log files that can be downloaded to a PC and viewed using display software. The delivery/ project-specific data reports can be configured to collect data from weather stations by data collection systems.
Chapter 2 __________________________________________________________ Product Overview When you start using the QML logger, the first thing you need to do is to define what parameters you want to measure and at what frequency.
