Patton Electronics Co. Surge Protected Modular Adapters Model 504, 505, 506, & 507

The Patton EPG Model 504, 505, 506 & 507 let you design your own custom surge-protected DB-25 or DB-9 to RJ-11 or RJ-45 modular adapters! You get to choose which DB-9 or DB-25 pins are protected, as well as which RJ-11 or RJ-45 pins they connect to. And for added flexibility, you choose between Silicon Avalanche Diode clamping voltages for RS-232 or RS-422 applications. All models divert up to 600 Watts per wire of surge energy to chassis ground through the D-type connector shell.
