TM7BDI16A

The Schneider Electric TM7BDI16A is a 16-channel, 24 V DC digital (discrete) input module for the Modicon TM7 distributed I/O system. It serves as a high-density, compact interface for connecting a large number of field devices such as pushbuttons, limit switches, proximity sensors (PNP/NPN), and other 24 V DC sensors to a TM7 network.

Parameters Parameter Specification Product Range Modicon TM7 Distributed I/O System Module Type Digital Input Module (Block I/O) Commercial Reference TM7BDI16A Number of Channels 16 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 4 mA per point at 24 V DC Input Configuration Grouped with common terminals (e.g., 8 points per common). Filtering Time Configurable (via software or DIP switches): Typically 1 ms, 3 ms, 5 ms, 10 ms. Isolation 500 V AC between field side and communication/power side. Connection Removable screw terminal block or pluggable connector (depends on specific variant). 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 interface (depending on the communication module it is paired with in the TM7 system). Power Supply 24 V DC (via integrated power connector or terminal block). Operating Temperature -25°C to +70°C (typical for TM7 blocks) Storage Temperature -40°C to +85°C Relative Humidity 10% to 95% (non-condensing) Protection Class Typically IP67 (when connectors are properly mated), suitable for harsh environments. Mounting Direct mounting via integrated holes or on a DIN rail (with adapter). Certifications CE, UL, cUL, RoHS compliant.
