Buying and selling used PLC output modules

Browse the used PLC digital output modules in this category and open individual product pages for purchasing options. Choose by PLC series, channel count, relay/transistor/triac output type, switched voltage and load current. For the basics, see PLC input and output modules.

Electrical compatibility: Check the module supply separately from the AC/DC voltage switched by its outputs. For transistor outputs, verify sourcing/sinking (PNP/NPN) wiring. For every output type, check per-channel and group current limits, load type and inrush current. A relay output alone does not establish suitability for switching a motor directly. Pulse applications also require verification of supported frequency and CPU functions; see high-speed pulse outputs for details.

Series compatibility and testing: Match the complete model code and revision to the supported CPU, rack or remote I/O station. Similar connectors or identical channel counts do not establish interchangeability. Ask the selling store whether front connectors and terminal blocks are included, which output channels were tested with which loads, and whether any channels have known faults.

Selling store and item condition: Your seller is the store identified on the product page; confirm price, stock, delivery, specifications and item condition with that store. Used, unused, boxed, repaired, faulty and parts-only items must be clearly distinguished, with known faults and missing accessories disclosed. Test scope, any warranty terms and declarations of conformity with standards are those stated in the selling store's product description. Boxed or unused equipment does not automatically come with a warranty.

Selling an output module: Email the brand, complete model code, quantity, working condition or known faults, clear photographs of the equipment and nameplate, and your asking price to otomasyonavm@gmail.com. Identify any faulty channels and missing connectors. We do not purchase equipment without an invoice. A submission does not constitute a commitment to buy. This section is not a platform where users publish their own listings.

Stock updates: Product listings are updated approximately every 10 days. A sold item may remain listed briefly; confirm availability with the selling store before ordering.
