Kann direkt mit PC verbunden werden zum schnellen Einrichten und zum Datenabruf
Überblick
Das Granite™ VOLT108 ist ein analoges Eingangsmodul, mit dem man einen Campbell-Datenlogger einfach erweitern kann. Es hat acht differentielle oder sechzehn single-ended Eingangskanäle und zwei Anregungskanäle. Angeschlossene Geräte können über einen 12 V- und einen geschalteten 12 -V Port mit Strom versorgt werden, außerdem gibt es zwei geschaltete 5 V -Ports zur Steuerung von Geräten. Das VOLT 108 verwendet einen 24-bit, AD-Wandler und hat sehr wenig Rauschen für bestmögliche analoge Messungen. Das VOLT108 unterstützt auch Period-average Messungen und bietet Anregungsstrom und -spannung.
Funktionen und Vorteile
- 24-bit AD-Wandler und geringes Rauschen auf den Eingängen
- Erweiterung der analogen Kanäle über den CPI Bus
- Erhöht die anzahl der Eingangskanäle aber nicht die Messzeit
- Einfach zu konfigurieren
- Rauschunterdrückung kann ausgewählt werden.
- CANbus 2.0 A/B Ausgabe möglich bei -XD Version
- USB 2.0 Anschluss zur direkten Verbindung mit dem PC

CPI Calculator v.1.0 (2.49 MB) 06-07-2016
The CPI Calculator is a downloadable Microsoft Excel spreadsheet used to estimate the usage and capacity of a CPI network. The calculator provides an overview on CPI devices including the CDM-A108, CDM-A116, CDM-VW300, CDM-VW305, and the CSAT3B. The calculator can also estimate the measurement speed of the CDM-A108 and CDM-A116 based on the number of channels and measurement parameters.
The CPI Calculator is an estimation tool and will help you better understand and design CPI networks by considering the following:
- What is the capability of each CDM or CPI device
- What is the CPI network capacity
- How much of the CPI capacity are the CDMs or CPI devices using
Volt100 OS v.06.03 (640 KB) 09-05-2023
Execution of this download installs the Volt108 / Volt116 Operating System on your computer which can then be uploaded to the Volt108 or Volt116 device with the Device Configuration Utility.

-
Yes, both 11-bit and the 29-bit (extended) message identifiers are supported.
-
All outputs except strain gauge calculated microstrain are supported in CANOut:
- VOLT SE/Diff output in mV
- BridgeFull in mv/V
- BrHalf3W and BrHalf4W in Rs/Rf
- TEMP 120 output in desired temperature units
Note: Strain values are in mV/V and either need a data logger or post processing to calculate microstrain.
-
in Burst Mode operation, repeated measurements are performed on the same channel for X number of times, then there is a waiting period for the measurements to be processed and transmitted to the data logger. No measurements can be made during this processing period. The maximum capture rate is 30 kHz on a single channel for a duration of 2.18 seconds (absolute maximum capability).
-
Only the XD versions (not the SD) support CANOut 2.0b. To enable this function, use our SURVEYOR software. When SURVEYOR recognizes an XD module, a CAN Enable menu appears with a “CAN Enabled” slider switch.
-
Yes, a specific CAN ID can be selected for each module.
-
in continuous scan mode (normal operation), 1 kHz on 1 channel is typical.
-
The VOLT 108/116 XD and TEMP 120 XD output CAN2.0b data frames in Big Endian byte format.
-
The CPI bus speed is adjustable in your CRBasic data logger program. Use the CPISpeed() instruction in your CRBasic program to adjust the CPI bus bandwidth to meet the following maximum combined (total) Ethernet cable lengths:
- 1000 kB/s for maximum combined Ethernet cable lengths of 15.2 m (50.0 ft)
- 500 kB/s for maximum combined Ethernet cable lengths of 61 m (200 ft)
- 250 kB/s for maximum combined Ethernet cable lengths of 152.4 m (500 ft)
