This protector will stop electrical transients such as spikes, surges and noise from
damaging strain gage load cells. Excitation voltage can be 18 VDC or +/-9 VDC or 9
VAC. This unit will clamp the excitation voltage to 20 VDC between + and - excitation
terminals, 75 VDC between any terminal and earth ground. Three active protection
stages on each of four lines. One active protection stage on the shield. Response time
on 20 VDC stage is 5 nanoseconds. Response time on 75 VDC stage is 100
nanoseconds. Resistance to ground is 7500 megohms minimum. Grounding is through a
1/4" lug to a 20 ft insulated #10 AWG ground wire(included). Two nylon strain reliefs for
0.187"-0.312" dia cable. Chemically resistant PVC enclosure is gasketed NEMA 1,2,3 and
11 intended for indoor and outdoor service. It is not NEMA 4 (washdown) or NEMA 6
