We make one, but it was for a specific application of a commercial customer and
doesn’t have DB9 connectors; it wires directly to terminal strips. It’s based
on our M-348 (rotator line/control line) product. It’s not on the website but
is available upon request.
Model M-346 is a new model using fast acting TVS diodes and gas discharge tubes
(GDT)
to achieve a lower clamping voltage for sensitive RS-232, RS-485 and RS-422
data lines.
TVS diodes and GDT’s were selected due to their low capacitance, minimizing
distortion
on serial data lines that might occur with other types of protection devices.
