5.2 Force sensors or load cells
Sensors with strain gauge signals are connected to the 14-way terminal strip. Several sen-
sors can be wired in parallel – up to 4 x 350 Ω or 8 x 700 Ω , depending on the sensor imped-
ance. Use 4-wire connection.
Terminal assignment:
Terminal Designation Colour *
1 (S+) Strain gauge output signal (+) white
2 (S-) Strain gauge output signal (-) yellow
3 (-AL) Strain gauge supply voltage (-) black
4 (+AL) Strain gauge supply voltage (+) red
The shield is connected to terminal 3.
* The colours refer to SIKA sensors with standard cables.
5.3 Relay outputs
The floating relay contacts are available on terminals 10 to 14 of the 14-way terminal strip.
The relays are controlled by the programmable switching points SP1 and SP2.
CAUTION! Maximum contact rating: 115 V
AC
, 0.2 A or 48 V
DC
, 0.2 A!
The maximum contact rating is only valid for purely resistive loads and must never be
exceeded. Switching inductive or capacitive loads in particular may cause large voltage
or current spikes.

Take suitable protective measures for your application.
