Accessories

CB15 Terminal Block U3 and UE9

READMORE

Provides convenient screw terminals for the DB15 connector on the LabJack U3 and UE9. The CB15 can connect directly to the LabJack or can be attached with various types of cables (not included). Not compatible with the U12. Includes screwdriver.

CB25 Terminal Block U12

READMORE

Most of the connections on the LabJack U12 have built-in screw terminals, but 16 of the digital I/O are accessed with a DB25 connector. To ease the use of these digital ports the CB25 provides screw terminal connections. For the LabJack U12 only.

CB37 Terminal Block UE9

READMORE

Provides convenient screw terminals for the DB37 connector on the LabJack UE9. The CB37 can connect directly to the UE9 or can be attached with various types of cables (not included). For the LabJack UE9 only. Includes screwdriver.

EB37 Experiment Board UE9

READMORE

The EB37 experiment board connects to the LabJack UE9’s DB37 connector and provides convenient screw terminal access. Also provided is a solderless breadboard and useful power supplies (+/-10 volts, 3.3 volts, and 1.25 volts). Includes a screwdriver, power supply, and jumper wires. For the LabJack UE9 only.

EI-1022 Temperature Probe

READMORE

Easy to use and inexpensive temperature probe. Designed to work with any LabJack, but can also be used with any voltage measuring device. Outputs 10 mV per degree C, and has a range of up to -40 to +100 degrees C.

EI-1050 Digital Temperature/Humidity Probe U12

READMORE

The EI-1050 uses two digital lines on the LabJack U12 (IO0 and IO1) to retrieve temperature and relative humidity measurements. Featuring the Sensirion SHT11 sensor, it provides 14-bit temperature readings and 12-bit humidity readings. An enable line is provided allowing multiple EI-1050 probes to be connected to a single LabJack U12. Measurement range is -40 to 120 degrees C for temperature and 0 to 100% for humidity. Accuracy is +/-0.5 degrees C (@ 25 deg C) and +/-3.5%. With LabJack U12 firmware version 1.10 or higher (Feb 2003 or later), it takes about 230/75 milliseconds to get a temperature/humidity reading. With earlier firmware versions it takes about 2 seconds to get one temperature or humidity reading. For the LabJack U12 only.

EI-1040 Dual Instrumentation Amplifier

READMORE

Dual instrumentation amplifier provides 2 high-impedance differential inputs. Operates from a single 5 volt supply and provides a +/- 15 volt supply and a 4.096 volt reference. Analog input range is +/- 10 volts. The gain of each channel is set to 1, 10, 100, or 1000 via digital I/O or jumper wires. Typical current requirement is about 80 mA @ 5 volts, allowing the EI-1040 to be powered from a +5V terminal on a LabJack.

RB16 Relay Board U12

READMORE

The RB16 provides a versatile method for electricians, engineers, and other qualified individuals, to interface a LabJack U12 with high voltages/currents. The included DB25 cable connects the RB16 to a LabJack U12. The RB16 has sockets for mounting up to 16 industry standard mini I/O modules (not included). The user can also install a resistor to bypass each socket and pass through the standard digital I/O line. For the LabJack U12 only.
