The Schneider TM5SDO2R is a two-channel discrete relay output module designed for Modicon TM5 automation systems. It provides two changeover relay contacts for switching AC and DC loads that require electrical separation from the controller output circuit.
Each relay channel can control loads up to 5 A at 30 VDC or 230 VAC. The module supports a total output current of up to 10 A and is suitable for industrial devices such as contactor coils, solenoid valves, indicator lamps, alarms, fans and auxiliary switching circuits.
The TM5SDO2R is installed on a compatible TM5 bus base and uses the TM5 distributed I/O architecture for compact machine-control cabinets. Its relay output design makes it useful where different load voltages are required within the same automation station.
For inductive DC loads, use an external flyback diode or suitable suppression device. For AC inductive loads, use an RC snubber or varistor where required to reduce switching transients and help protect relay contacts.

Installation and Selection Notes
Install the TM5SDO2R on a compatible TM5 bus base only. Confirm the load voltage, inrush current and switching frequency before selecting the module. Do not exceed 5 A per relay channel or 10 A total output current. Add appropriate suppression devices for inductive loads to help reduce contact wear and electrical interference.
