MTL4781+ FOR FOUR SWITCHES solid-state output.

The MTL4781+ is a barrier with four switch channels plus one supply channel. It has electronic overvolt protection and is designed solely for switch applications. It can interface with up to four hazardous-area switches or two relay/changeover contacts, providing four solid-state open-collector returns to the safe area. The status of all four switches is indicated by a bank of four LEDs on top of the module. The fifth channel is a single power output channel for all switches made available through two hazardous-area terminals. The module includes a current limit circuit which prevents the safety fuse blowing if short-term overvoltages are inadvertently applied to any of the safe-area terminals.

It is also reverse polarity protected. The module is capable of operating from bussed power.
