Product questions
What voltage and output type does the NX-OD5256 use?
The NX-OD5256 has 16 PNP transistor outputs rated at 24 V DC. Omron specifies a 15–28.8 V output operating range; the 12–24 V wording in some listings should not be treated as its nominal rating.
How much current can the NX-OD5256 outputs handle?
The maximum load current is 0.5 A per output and 4 A for the entire unit. The total limit means all 16 outputs cannot each carry 0.5 A simultaneously.
What terminal connection does the NX-OD5256 use?
This unsuffixed model is 12 mm wide and uses a detachable screwless push-in terminal block with one-wire connections. Omron lists the NX-TBA162 as its replacement 16-terminal connector. Confirm the complete part number, including any suffix, before ordering.
Can the NX-OD5256 be used as a safety output module?
Omron identifies the NX-OD5256 as unsuitable for safety functions. It has short-circuit-protected outputs, but that does not make it a safety-rated output unit.
Will the NX-OD5256 fit my control system?
It uses the NX I/O bus, but this alone does not establish compatibility with every controller or machine. Provide the controller and coupler model, equipment serial number and existing module number so the configuration can be checked.
