Datalogger Channel Extension Capabilities on the GL840
The standard configuration of GL840s come with a detachable terminal.
The Multi-input model (GL840-M) has a removable terminal B-564, and the
Withstand Voltage model (GL840-WV) has a removable terminal B-565.
Example of standard configuration expanded to 40 channels
To add or expand additional channels, the original terminal from the
main body connects with the B-566 Terminal Base allowing you to add
additional terminals for up to 200 channels or 10 terminal blocks.
Expand channels by
connecting Terminals and Base
