Precautions about connection to the signal input/output terminal block are given below.
The precautions described here are important for safety.
Please properly understand the descriptions before connection.
4-1. Load Cell Connection
The excitation voltage of the F805AT-CK is 10V DC/5V DC selectable at 120 mA. Up to 4 load cells
(350 ohm) may be connected in parallel (when excitation is 10V). A 7-pin (Hirose JR16PN-7S) round
connector is supplied.

WARNING
●
Do not connect a commercial power source directly to the signal input/
output terminals.
●
Connect to the signal input/output terminals with no power applied
because it may cause an electric shock.
●
For connection to the signal input/output terminals, check the signal
names and pin assignment numbers, and then carry out wiring properly.
●
After wiring, be sure to mount the attached terminal block cover.
Otherwise, it may cause an electric shock.
(Power input terminal at the DC Spec. or RS-485 terminal block.)
●
Before applying power, carefully check the wiring, etc.
●
Do not touch any signal input/output terminal while applying power. Doing
so may cause electric shocks or malfunctions.
