Operating with a 5V DC TTL sourcing configuration (+4.5V to 5.5V DC range), this module features inverted logic functionality (-0.2 to 0.8V DC corresponds to an ON state) for direct interfacing with Transistor-Transistor Logic signals and high-speed sensors. Equipped with a Removable Terminal Block (RTB) for simplified wiring and maintenance, the module consumes 0.140A (140 mA) at 5V DC backplane current while featuring a net weight of \u003cstrong style=\"color: #003366;\"\u003e0.3 kg\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #003366;
