Schneider Electric STBDRC3210 Advantys STB 2-Channel Relay Output Module

Schneider Electric STBDRC3210 Advantys STB Relay Output Module

The STBDRC3210 is a standard 2-channel relay output module from the Schneider Electric Advantys STB series. It switches 24V DC or 115/230V AC field devices. Each channel supports up to 2 A. The module uses C-type (Form C) relay contacts. It offers 1780V AC field-to-bus isolation. Hot swapping is supported for fast replacement. This module fits the STBXBA2000 I/O base. It works with the STBPDT3100 24V DC PDM. The STBDRC3210 is discontinued. Schneider Electric now points users to the Modicon X80 range. Oiltech Controls still supplies tested units for legacy systems.

Key Technical Data

Installation Guide

• Mount the STBXBA2000 I/O base on a DIN rail.
• Connect the STBPDT3100 PDM for 24V DC supply.
• Insert the STBDRC3210 into the base.
• Wire field devices to the C-type relay contacts.
• Keep the load within 2 A per channel.
• Use hot swapping only in safe conditions.

Commissioning and Maintenance

• Check wiring before power-up.
• Confirm the PDM output is 24V DC.
• Test each relay channel with a known load.
• Inspect contacts for wear in high-cycle jobs.
• Replace the module if relay operation becomes unstable.
• Hot swap reduces downtime in live systems.

• Works with the Advantys STB I/O system.
• Requires the STBXBA2000 base.
• Requires the STBPDT3100 PDM.
• Field signals can be 24V DC or 115/230V AC.
• Not a direct drop-in for Modicon X80 racks.
• Use as a legacy replacement or spare part.

Diagnostics and Application Scenarios

The STBDRC3210 provides basic relay output status through the control system. It does not include advanced channel-level diagnostics. Engineers use it for simple ON/OFF control. Typical uses include:

• Relay control of small AC or DC loads
• Legacy Advantys STB I/O upgrades
• Factory automation retrofit projects
• Building control panels with mixed voltage signals
• Spare part support for discontinued lines
