Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•[PART NUMBER & SPEC CHECK] 1-pack 161-3128 replacement relay for compatible 24VDC systems. Match 161-3128 / 1613128, 5-pin micro relay body, terminal numbers 85/86/30/87/87a, and the original relay diagram before ordering.
•[5-PIN LAYOUT CHECK] Printed diagram shows a 24VDC 5-pin changeover-style relay with coil terminals 85/86 and load terminals 30/87/87a. Compare the socket cavity, blade spacing, terminal orientation and original marking; do not use for a 4-pin relay socket or a different voltage
•[COMPATIBLE WITH CATERPILLAR / CAT EXCAVATORS] Compatible with selected Caterpillar / CAT excavator applications using 161-3128, including model families such as 320D, 320E, 323D, 324D, 330D, 336D, 345C, 349D, 349E, 349F and related suffix variants. Verify by equipment parts diagram.

•[FUNCTION / CIRCUIT CHECK] This relay may be used in different electrical relay or fuse-box circuits depending on the machine model and relay cavity. Confirm the circuit name from the fuse/relay box label, service manual or parts diagram before replacing.
•[VISIBLE MARKING CHECK] Product photos show 161-3128, 24VDC, terminal diagram and C2416-04 housing marking. Use C2416-04 only as a visible housing/marking check, not as a separate replacement number or interchange claim.
•[INSTALLATION NOTE] Disconnect power before service, pull the old relay straight out, install with the same blade orientation, and inspect the socket for corrosion, moisture, heat damage or loose terminals. Replace only after confirming relay failure or a matching part-number diagnosis.
•[COMPATIBILITY NOTE] Equipment names, brand names and part numbers are used only to verify compatibility. Confirm original part number, voltage, pin count, terminal layout, relay marking and equipment configuration before ordering.
