We do our best to fulfill every request, but some parts are unavailable. Your patience and understanding is appreciated.
Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.
Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.
Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.
Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.
Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.
Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.
After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.
IPC Station is a website of GID Industrial, an ISO 9001:2015-certified company that has specialized in servicing industrial computer boards and providing other industrial products for sectors including manufacturing, defense, aerospace, entertainment, healthcare, and more by utilizing our combined skills and vast international network of trusted suppliers since our founding in 2015.

The control recognises cross-short, cable break and earth leakages in the monitoring circuit. F1 = hybrid fuse Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. For 1-channel control, connect NC contact to S11/S12 and bridge S12/S22 Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X3. If the feedback circuit is not required, establish a bridge Time delay: The time-delayed safety enable 37/38 is adjustable for 1 to 30 seconds drop-out delay (see setting intructions). The safety enabling circuit 37/38 conforms to EN 60204-1 for STOP Category 1. The safety enabling circuits 13/14 and 23/24 conform to EN 60204-1 for STOP Category 0. Setting of the drop-out delay time is carried out by means of a potentiometer from the front of the enclosure. The wiring diagram is shown with guard doors closed and in de-energised condition.
