    • Cable set, 24 V DC power block to analog terminal block
    • Cable set, data logger to analog terminal block
    • Data logger data cable
    • Data logger holder
    • Terminal block accessories for 4 analog input channels
    • Document Vaisala CAB100 Assembling Analog Channel Terminal Block Technical Note (M212262EN)
  • DL4000 data logger(s), 1 logger per 4 analog input channels
  • Small flat head screwdriver

For item codes, see Spare parts and accessories.

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 Analog Wiring Set before you install and connect them.
DL4000 data loggers are delivered with default factory settings. This applies both to the factory-installed data loggers and the ones delivered as spare parts. For instructions on configuring measurement units and scaling in the data loggers, see the Vaisala viewLinc Enterprise Server User Guide for your viewLinc version, available at

Follow the steps below to install terminal blocks for analog input channels as new devices to an empty DIN rail in CAB100B.

You can apply this installation procedure also when expanding the number of analog input channels in the cabinet. For example, to increase the number of analog input channels on a DIN rail from 4 to 12, order 2 Analog Wiring Sets and 2 data loggers.

Refer to CAB100B layout diagrams when planning the installation.

  1. De-energize the cabinet:
    1. Switch off mains power and the circuit breaker located inside the cabinet.
      Circuit breaker
    2. Only when expanding the analog terminal block installation on a DIN rail:
      Disconnect the analog channel 24 V DC power cable connector from the power block, located on the right-hand side of the cabinet.
  2. Remove the cable duct cover below the empty DIN rail reserved for the analog terminal block.

    Remove also the long vertical cable duct cover in the middle of the cabinet.

  3. Assemble the new analog channel terminal block.

    See the instructions in Vaisala CAB100 Assembling Analog Channel Terminal Block Technical Note (M212262EN), included in the Analog Wiring Set (ASM213078SP).

  4. Mount the analog channel terminal block on the DIN rail.
  5. Assemble the data logger holder.
    1. Place the data logger in the logger holder.
    2. Fit the cover into place.
    3. Tighten the screw by hand.
  6. Connect the logger data cable to the RS-232 serial port in the data logger.

    Use a small flat head screwdriver to tighten the screw attached to the connector.
