TM7SDI8DFS

The Schneider Electric TM7SDI8DFS is an 8-channel, 24 V DC digital input module for the Modicon TM7 distributed I/O system. Designed for robust and reliable signal acquisition in harsh environments, it provides a high-density interface for connecting field devices such as pushbuttons, limit switches, and proximity sensors directly on the machine or production line.

Parameters Parameter Specification Product Range Modicon TM7 Distributed I/O System Module Type Digital Input Module (with Fast-Connect "FS" connectors) Commercial Reference TM7SDI8DFS Number of Channels 8 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 3-4 mA typical) "0" Signal Level ≤ 5 V DC Input Current Typically 3-4 mA per point at 24 V DC Input Configuration Likely grouped with common terminals (e.g., 4 points per common). Filtering Time Configurable (via software or DIP switches): e.g., 1 ms, 3 ms, 5 ms, 10 ms. Isolation 500 V AC between field side and communication/power side. Connection Industrial M8 or M12 circular connectors (male or female, depending on variant) for fast, reliable, and sealed connections. Diagnostic LEDs Green LED per channel (indicates "ON" state). Module STATUS LED (Green/Red for power, communication, and error). Communication Interface Integrated CANopen or Modbus TCP (via the TM7 communication head). Power Supply 24 V DC (via a separate power connector, often also an M12 type). Operating Temperature -25°C to +70°C Storage Temperature -40°C to +85°C Relative Humidity 10% to 95% (non-condensing) Protection Class Typically IP67 (when connectors are properly mated). Vibration/Shock Resistance Designed to withstand industrial vibration and shock. Mounting Direct mounting via integrated holes or on a DIN rail (with adapter). Certifications CE, UL, cUL, RoHS compliant.
