The GE Pulse Rate Input Board DS3800HPRB1D1C is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Pulse Rate Input Board DS3800HPRB1D1C also is populated with 12 jumpers and 1 trimmer resistor. The board also is populated with 1 programmable interrupt controller, multiple programmable interval timer devices, and multiple capacitors.
The programmable interrupt controller and programmable interval timer components are logic devices that are sensitive to static electricity. The boards require special consideration when you handle or work on them. Static can interfere with the firmware and programming code stored on the modules. It can make the code unuseable by the modules. When you handle the board, always wear a static protective wrist strap. A cable connects the 2 ends of the device. One end touches your arm or wrist. The other end is a clip that you clamp to a metal grounded surface. This can be a metal chair leg or a metal support on a work table. Some wrist straps end with a connector that is designed to fit in a plug on a work table. This provides a fast and secure connection. The metal is a grounded surface. The static seeks out the grounded surface and exits your body or the board. In this way the board and the programmable devices are protected.
When you receive the board keep it in the protective bag. The bag prevents static from entering the board. Also store the board in a safe place in the shipping box.
