Module fit and input characteristics
The TM5SDI12D is a 12-point discrete input module for the Modicon TM5 platform. It accepts 24 V DC sink signals from field devices like proximity sensors and limit switches, with a guaranteed ON threshold above 15 V and OFF below 5 V. Each channel draws 3.75 mA at 24 V DC, and the module consumes 1.93 W typical. The sink (NPN) logic matches common sourcing PLC interfaces when wired correctly.
