Parameters Parameter Specification Product Range Modicon TM3 Modular I/O System Module Type Digital Input Module Commercial Reference TM3DM24RG Number of Channels 24 Input Type Sink/Source (PNP/NPN) compatible Nominal Input Voltage 24 V DC (SELV / PELV) Input Voltage Range 19.2 V DC to 30 V DC "1" Signal Level ≥ 15 V DC (at 3 mA typical) "0" Signal Level ≤ 5 V DC Input Current Typically 3 mA per point at 24 V DC Input Configuration Grouped in sets of 4 channels with one common terminal per group. Filtering Time Configurable per group of 8 channels: 0.5 ms, 1 ms, 3 ms, 5 ms, 10 ms. Isolation 500 V AC between field side and bus side. Channels within a group are not isolated from each other. Connection Removable screw terminal block. Diagnostic LEDs Green LED per channel (indicates "ON" state). Module STATUS LED (Green/Red for power, communication, and error). Bus Interface TM3 bus via connection to a TM3 base (e.g., TM5SBER2). Power Consumption From 5V bus: 115 mA (typical). From 24V field supply: depends on connected sensors. Operating Temperature 0°C to +60°C Storage Temperature -25°C to +70°C Relative Humidity 10% to 95% (non-condensing) Protection Class IP20 (when mounted on a base in an enclosure). Certifications CE, UL, cUL, RoHS compliant.
