1669 Series – Transient Protector
Used for full weather protection of ?eld transmitters and instrumentation operating on 24-28 V systems, the 1669 Series protects
sensitive I/O circuitry from surges of any polarity or magnitude. Principal use is on 4-20 mA control loops and can be used on
grounded (+ or -) or ungrounded circuits. Able to survive and protect even from direct lightning strikes to the transmitter ground or
?eld wiring. Automatic recovery after passage of the surge. Long life, high operational reliability.
Construction is hybrid 3-stage design, using a high surge capacity Balanced Trigard ? Gas Tube protector, coordination impedance
and silicon suppressors to provide differential and common mode protection with very low clamping levels for delicate loads. The
housing is thick walled schedule 40, type 303 stainless steel. Wiring is #20 (.5 mm 2 ) 1000 V, PVC insulated. Solid red and black colors
are used for the input; striped colors signify the protected output. The protector ground wire (green) is electrically bonded to the
metallic housing; it is for connection to the grounding screw within the ?eld device. Use Model 1669-02/06 for standard ground
resistance conditions.
Use Model 1669-01 / 05 with higher voltage isolation to ground for sites with high resistance soil conditions or where signi?cant
ground potential differences are known to exist.
