Our Process

Our Process: Preparation
Preparation

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.

Our Process: Receiving
Receiving

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.

Our Process: Initial Testing
Initial Testing

Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.

Our Process: Refurbishment
Refurbishment

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.

Our Process: Repair
Repair

Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.

Our Process: Final Testing
Final Testing

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.

Our Process: Shipping
Shipping

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.

Floatless Level Switch (Compact Type) 61F-G@N CSM_61F-G_N_DS_E_3_3 Improved Design for a More Lightweight Construction and Reduced Standby Power Consumption. • Standby power reduced to 85% or less of previous models. (Applicable to 61F-GN.) Weighs only 85% or less of previous models. (Applicable to 61F-G3N/-G4N.) Easy identification of operating status with LED operation indicator. Increased reliability of internal relay (micro load: 5 VDC, 1 mA) to enable PLC input. Electrode terminals and other wiring terminals are separated for easy wiring. Select from three mounting me thods: JEM, DIN rail mounting, or screw mounting. Note: LED operation indicator is provided on Controllers manufactured in August 1999 or later.

This arrangement is called a two-wire connection. Three Electrodes are still required. Both the 61F Controller (including the Relay Unit) and Electrode Holder must be two-wire models. Two-wire Electrode Holders have an in-built resistor of 6.8 kΩ 1W.
