The 138708-01: Real-World Reliability
It is always the same story: 2 AM, the control system alarms, and the spare parts cabinet is empty. The Bently Nevada 138708-01 — a i/o module — is the component that failed. Now you are calling suppliers, hoping someone has stock and can ship today.
That is the scenario we built PLC Parts Direct to solve. We stock the 138708-01 in our Shenzhen warehouse — physically, not virtually. When you order, our team picks it from the shelf, verifies the serial number against the test report, packs it in anti-static packaging, and hands it to DHL. You get a tracking number, not a processing status that drags on for weeks.
What you are getting: four input channels: Accommodates signals from up to four absolute shaft encoders simultaneously.; size: 2.5 cm x 11.2 cm x 24.2 cm; weight: 0.4 kg; manufacturer: Bently Nevada. Every unit undergoes multi-point functional verification and 48-hour burn-in at 55°C before shipping. A printed test report is included. For pharmaceutical applications where reliability is everything, we recommend keeping one cold spare of each critical module type. The cost of the spare is negligible compared to the cost of unplanned downtime.
