Used for full weather protection of field 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 field 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 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 field device.
Use Model 1669-01 / 05 with higher voltage isolation to ground for sites with high resistance soil conditions or where significant ground potential differences are known to exist. This double ended type is used when the field instrument has only a single conduit entry port; the protector attaches to the instrument, and the connection to the field wiring is made inside an external, appropriately rated box connected to the other end of the protector.
