Sensor Connection
Connect the sensor/s to the terminal block/s at the top of data logger:
Figure 11: OM-DAQLINK logger sensor inputs
Sensors do not have to be added successively. You may only configure In-4, or configure In-1
and In-3, for example, when setting up the logger via the software.

Programming Limitations for OM-DAQLINK-TEMP and OM-
DAQLINK-TEMPRH
The standard sampling rate for all sensors on all inputs is from a maximum of one sample every
second to a minimum of one sample every 18 hours. However, there are certain limitations
using a specific combination of sensors, which must be taken into account when programming
the OM-DAQLINK data loggers.
Note: The software integrates all programming limitations automatically when configuring the
loggers.
Please refer to the table below for OM-DAQLINK programming limitations, where:
PT100, Thermocouple J, K or T

DAQLINK-TEMPRH)
