Schneider Electric TM2DRA8RT Discrete Relay Output Module

Engineers select the Schneider Electric TM2DRA8RT discrete output module to expand Modicon M238 logic controller capabilities significantly. Schneider Electric designs this versatile expansion unit to drive industrial loads through eight highly reliable open relay contacts. This compact relay module maintains total signal isolation while delivering dependable switching performance across automated industrial machinery.

Technical Specifications

• Brand and Manufacturer: Schneider Electric manufactures top control hardware for Modicon M238, Twido, and Advantys OTB automation series.
• Model Identifier: The TM2DRA8RT module offers eight discrete relay output channels organized into two separate common point groups.
• Channel Current Load: Each normally open output channel handles up to 2 A continuous current at 240 V AC.
• Maximum Group Capacity: Each common terminal supports a total maximum current capacity reaching up to 7 A simultaneously.
• Switching Response Speed: The relay contacts close within 10 ms and open within 5 ms during operations.
• Contact Resistance Performance: Premium internal relay contacts maintain low initial electrical resistance under 45 mOhm for efficient conduction.
• Minimum Switching Threshold: Precision contacts trigger reliably at low signal levels down to 0.1 mA at 0.1 V DC.
• High Voltage Isolation: Robust internal construction provides up to 2300 V dielectric strength between output channels and logic circuits.
• Mechanical Endurance Rating: Internal relay mechanisms achieve an outstanding operational life span of 20,000,000 mechanical switching cycles.
• Internal Power Consumption: Logic circuits draw low operating currents of 30 mA at 5 V DC during output activity.

Key Features and Value

• Removable Terminal Connection: Technicians wire field devices quickly using a practical removable screw terminal block system.
• Comprehensive Quality Guarantee: We support every genuine expansion card with a complete 12-month factory warranty covering defect replacement.
• Compact DIN Rail Form: The slim 27.3 mm width mounts directly onto standard 35 mm symmetrical DIN rails effortlessly.

Installation Guide

• Snap the module securely onto the 35 mm DIN rail next to your Modicon controller expansion base unit.
• Tighten all field wiring securely inside the removable terminal block before attaching it to the plastic housing.
• Verify external load voltage levels before energizing output circuits to prevent exceeding maximum hardware operating limits.

Packing and Delivery

• Factory packaging includes one individual discrete relay module sealed inside protective anti-static industrial packaging materials.
• Logistics teams dispatch urgent international customer orders rapidly using trusted express carriers FedEx, UPS, and DHL.
