Parameters Parameter Specification Product Range Modicon TM2 Modular I/O System Module Type Configurable Digital I/O Module (DI/DO Relay) Commercial Reference TM2DMM8DRT Number of Points 8 Point Configuration Each point individually configurable as: • 24V DC Digital Input (Sink/Source compatible) • Relay Digital Output (SPDT - Form C contact) Input Specifications (when configured as DI) Voltage: 24 V DC nominal (19.2 - 30 V DC) "1" Level: ≥ 15 V DC Input Current: ~4 mA Filtering: Configurable Output Specifications (when configured as DO) Contact Type: SPDT (Form C) Relay - 1 Normally Open (NO) + 1 Normally Closed (NC) Max. Switching Voltage: 250 V AC / 30 V DC Max. Switching Current: 2 A (resistive load @ 30°C) Electrical Life: Varies with load (e.g., ~100k ops @ 2A, 250V AC resistive) Configuration Method Via software (SoMachine or EcoStruxure Machine Expert) using the connected controller. Isolation 1500 V AC between relay coil and contacts; 500 V AC between field side and bus side. Connection Removable screw terminal block. Diagnostic LEDs Green LED per point (indicates point status: ON for input active or output energized). Module STATUS LED (Green/Red for power/communication/error). Bus Interface TM2 bus via a TM2 base (e.g., TM2XMTGB). Power Consumption From 5V bus: ~110 mA (typical). From 24V field: depends on configured inputs/outputs and loads. Operating Temperature 0°C to +60°C Storage Temperature -25°C to +70°C Relative Humidity 10% to 95% (non-condensing) Certifications CE, UL, cUL, RoHS compliant.
