Industrial Automation Parts Supplier Serving Pomona, CA

In Pomona electronics and electrical equipment manufacturing, a failed PLC or drive can cost thousands of dollars per hour in lost throughput, scrap, and overtime. Waiting days while a vendor “checks with their sources” is not an option when a test bench, SMT line, or panel build is stalled. Faster sourcing changes that math.

PLC Department supports Pomona manufacturers and construction and electrical contractors with quick access to industrial automation parts from US inventory and a wide supply network. From your shops and job sites in Pomona to nearby Montclair and La Verne, we help you track down the exact PLC, HMI, VFD, servo, or control module you need, including obsolete Allen‑Bradley, Siemens, Mitsubishi, Omron, Schneider, and GE Fanuc items that local channels have given up on.

For controls engineers building new panels or retrofitting older equipment, we can source both current production hardware and discontinued CPUs, I/O, comms modules, and operator interfaces so you can keep proven designs in service. Construction and electrical firms working on industrial TI projects rely on us for hard-to-find breakers, soft starters, and drives that match existing gear, reducing redesign time and change orders when site conditions do not match the prints.

Every tested surplus and new-open-box part from PLC Department comes with a 1-year warranty and is inspected before it leaves our warehouse. You get clear condition grading and honest information instead of surprises on the jobsite. Our team issues fast, written quotes, accepts purchase orders from approved accounts, and can coordinate shipments directly to plants and contractors across Pomona and the surrounding area.

When a failed control card shuts down a production cell or an MCC drive failure threatens a construction schedule, you can call (833) 800-7748 and tap into a sourcing group that spends all day hunting down difficult automation SKUs. We focus on finding what others cannot, so your maintenance and project teams spend less time chasing parts and more time getting Pomona equipment back online.
