1669 Series – Transient Protector
Specifi cations are subject to change without notice. The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. Users should verify actual device performance in their specifi c applications. Used for full weather protection of fi 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 ground- ed (+ or -) or ungrounded circuits. Able to survive and protect even from direct lightning strikes to the transmitter ground or fi 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 diff erential 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 mm2) 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 fi 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 signifi cant ground potential diff erences are known to exist.

This ‘double ended’ type is used when the fi eld instrument has only a single conduit entry port; the protector attaches to the instrument, and the connection to the fi eld wiring is made inside an external, appropriately rated box connected to the other end of the protector. The ‘single ended’ protectors are useful for fi eld devices with dual conduit ports; the fi eld wiring connects to one port while the 1669 protector connects into the second - all connections are made within the instrument’s wiring cavity. This installation simplifi es the task of maintenance or of adding a protector into an existing loop. 16691669-01, 1669-02 (For control room protector use 1820-28-A1/A3) 1669-05, 1669-06 (For control room protector use 1820-28-A1/A3) EQUIP 1669 LINE How To Order 1669 - XX Model Number Designator 01 05 02 06 1669-01, 1669-02 1669-05, 1669-06 REV.
