Part # / modbus resistor

BillP · ‎2021-06-28

I use AP8841; I've lost the resistors used to daisy-chain these boxes. I'd like to purchase more. What is the part #?

Hi Stuart these are CAN bus terminators, nothing to do with Modbus.

The part numbers are 0W4161A or lower profile version 0W05545A.

The ordering preference I would suggest is:

0J-0W05545A - qty 2 of 0W05545A so plan accordingly on the number you need 2 are required per PDU group you create Up to (4) PDUs in a group.
If above isn't available, there may be availability of the individual part #, which is 0W05545A.
Then, if those aren't available in a timely manner, 0J-0W4161A and 0W4161A may be available for qty 2 and 1 respectively. These are not as low profile though and stick out of the PDU display..but they will work.
