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.

The shield is connected to terminal 3.
* The colours refer to SIKA sensors with standard cables.

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.
