6.7 Expanding galvanic isolator
installation in CAB100B
• Galvanic Isolator Wiring Set (Vaisala item code: ASM213143SP). The set contains the
following:
• Galvanic isolator cable
• Data logger data cable
• Partition plate
• Data logger holder
• DL4000 data logger(s), 1 logger per 4 galvanic isolators
• Small flat head screwdriver
For item codes, see
Spare parts and accessories (page 119)
The partition plate is needed for isolating the intrinsically safe area from the non-
intrinsically safe area inside the cabinet.
Each set of 4 galvanic isolators requires a Galvanic Isolator Wiring Set and a data logger
of its own.
You can install only one type of device or measurement point (PDT101 transmitters, analog
input channels, safety barriers, or galvanic isolators) per row in the cabinet.
In cabinet models with 5 to 8 data loggers, you need 2 serial port servers.
One serial port server controls the traffic of maximum 4 data loggers.
Make sure to number the data loggers as well as the cable sets and wires in the Galvanic
Isolator Wiring Set before you install and connect them.
Follow the steps below to add new galvanic isolators to an existing set of devices in
CAB100B. Refer to
CAB100B layout diagrams (page 135)
when planning the installation.
For instructions on introducing galvanic isolators as new devices to an empty DIN rail in the
cabinet, see
Adding galvanic isolators as new modules to CAB100B (page 78)
