Modicon TM3DM24R Discrete I/O Module - 24VDC, 16 Digital Inputs & 8 Relay Outputs

The TM3DM24R is a robust Modicon TM3 discrete I/O module designed to expand the input and output capabilities of various Modicon programmable logic controllers, including the M221, M241, M251, and M262 series. This module provides a total of 24 I/O points, featuring 16 discrete inputs (IEC 61131-2 Type 1, sink or source logic) and 8 normally open (NO) relay outputs. The inputs operate on a 24V DC logic, while the relay outputs offer versatility with support for both 24V DC and 240V AC, capable of handling up to 2000 mA. Each I/O channel is equipped with a green LED indicator for clear local signaling of its state.

The TM3DM24R module is built for reliable performance in industrial environments. It boasts an impressive mechanical durability of 20 million cycles and features quick 4 ms turn-on and turn-off response times for inputs. The module is engineered with robust insulation, providing 1500 VAC between input and output groups and 750 VAC between open relay contacts, ensuring electrical isolation and system integrity. Connectivity is facilitated through removable screw terminal blocks (17 terminals for inputs, 11 for outputs), accommodating wires up to 1.5 mm². It complies with various international standards including IEC 61131-2 and carries multiple certifications such as cULus, CE, UKCA, RCM, and EAC, including cULus HazLoc. The module operates reliably within a wide temperature range, from 14°F to 131°F (-10°C to 55°C) depending on installation orientation, and maintains an IP20 degree of protection with its protective cover in place. It is designed to withstand harsh industrial conditions, demonstrating high resistance to electrostatic discharge, electromagnetic fields, fast transients, and vibrations.

This discrete I/O module is an essential component for extending the reach of Modicon PLCs in diverse automation applications. It is particularly suitable for systems requiring additional digital sensing and control points, such as in machine control, process automation, building management, and material handling. Its relay outputs make it ideal for switching higher power loads directly, simplifying wiring and reducing the need for external interposing relays. The module's robust design and comprehensive certifications ensure dependable operation in demanding industrial settings.
