CABLE
NOTE 1: This ground connection is recommended for best results. If your sensors
are inherently connected to ground, use caution and avoid making additional ground
connections which could generate ground loops and measurement error.
NOTE 2: Shielded cable is recommended. For best results, ground the cable shield
at the end of the cable closest to the greatest potential source of EMC disturbance.
✓
Connect 15-36V DC to the power terminals labeled DC+ & DC-.
Observe proper polarity. For supply connections, use No. 14 AWG
wires rated for at least 75
C.
CAUTION:
Do not exceed 36VDC peak.

NOTE: For rated performance
and adherence to applicable
standards, you must connect
earth ground to the GND
terminal at TB3-33 as shown.
CAUTION: Risk of Electric Shock
– More than one disconnect switch may
be required to de-energize equipment before servicing.
IMPORTANT
– External Fuse:
If unit is powered from a supply capable of
delivering more than 1A to the unit, it is recommended that this current be
limited via a high surge tolerant fuse rated for a maximum current of 1A or
less (for example, see Bel Fuse MJS1).
✓
Connect analog input signals to the input terminals as shown below
according to your model.
✓
Connect Earth Ground as shown in the connection drawings above.
Additionally, always connect the GND terminal (TB3-33) to earth ground.
The ground connections noted are recommended for best results. If
sensors are already grounded, use caution and avoid making additional
ground connections which could create ground loops.
TIP
: For best performance, the cable shield ground should be connected
at the end that is closest to potential sources of disturbance.
The plastic module housing does not require earth ground.

Analog Inputs
Input is a type J, K, T, E, R, S,
B, or N thermocouple, ±100mV
DC, or ±1V DC.
Ground inputs as shown.
Inputs are not isolated
channel-to-channel, except for
small common mode
difference voltages up to ±4V
peak.
Earth Ground
Warning: To comply with
safety and performance
standards, use shielded cable
and connect earth ground as
noted. Failure to use good
wiring and grounding practices
may be unsafe and hurt
performance.
