System Check Module: This module has no protection components used to temporarily replace protection modules to troubleshoot and test. It allows the signal to pass directly from the input side to the output side of the DLP-31xx & DLP-37A motherboard.
There is no "one size fits all" surge protector. Misapplying surge protection results in money being spent and equipment remaining vulnerable to damage. The DLM4 modules protect 4 wires each and address countless applications and project budgets. They are used with MCG models DLP-3131, -3132,-3132-10, and -37A motherboard assemblies. Using a modular data/signal line protector permits customization: choose a motherboard and select the modules that best fit your application. Modules are easily serviced in the field, replaceable in 5 seconds (motherboard wiring does not have to be disconnected).
All of the DLM4 modules can be used with the DLP-31xx series & DLP 37A motherboards. Different DLM4's can be used in the same motherboard to match the protection module with the circuit. Specifiers often use a modular system in regions of high surge activity, in remote sites, and when mean time to repair (MTTR) must be minimized. Such a protection system results in the most suitable protection circuit being employed so that optimum performance is achieved and downtime surges is eliminated.
