Schneider STBDRC3210 Relay Output Module 24V DC

Schneider STBDRC3210 Modicon STB Relay Module

Product Introduction

The Schneider STBDRC3210 belongs to the Advantys STB distributed I/O platform. This standard relay output module provides 2 channels with C-type (Form C) contacts. Specifically, each channel handles loads up to 2 A, covering both 24V DC and 115/230V AC circuits. Furthermore, the STBDRC3210 delivers 1780V AC field-to-bus isolation for dependable separation. Therefore, it suits mixed-voltage applications where flexible switching matters most.

Technical Specifications

Each output channel uses a Form C (C-type) relay contact arrangement. Moreover, the contacts switch either 24V DC or 115/230V AC loads at up to 2 A per channel. The coil operates at 24V DC, which keeps control-side wiring simple. Additionally, the field-to-bus isolation withstands 1780V AC, protecting the logic bus from field transients.

The STBDRC3210 supports hot swapping when paired with a standard network interface module. This feature allows replacement without disrupting other stations on the network. Power for the module arrives through the STBPDT3100 power distribution module at 24V DC. Besides, the module mounts on the STBXBA2000 I/O base, which measures 18.4 mm in width. Consequently, cabinet space stays efficient in dense installations.

Mechanical and Environmental Parameters

The module shares the compact Advantys STB form factor. Its width measures 18.4 mm, allowing tight side-by-side mounting on a 35 mm DIN rail. In addition, the product weighs approximately 0.130 kg. The housing carries an IP20 protection rating, so it belongs inside a control cabinet.

For environmental tolerance, the operating temperature spans 0°C to 60°C. Meanwhile, storage temperature extends from -40°C to 85°C. The module also withstands 95% relative humidity at 60°C without condensation. Moreover, it resists vibration at 3 gn on standard DIN rails. These ratings support reliable performance in typical factory conditions.

Installation Guide

First, snap the STBXBA2000 I/O base onto a 35 mm DIN rail. Next, slide the STBDRC3210 module onto the base until it locks firmly. After that, wire the relay contacts to the load circuits. Additionally, confirm the STBPDT3100 supplies 24V DC power to the module. Finally, check the status LEDs to verify correct channel operation.

The module supports hot swapping with standard NIMs. However, always follow local electrical codes during installation. For instance, de-energize field circuits before wiring if safety procedures require it.

FAQ

Q1: What contact type does the STBDRC3210 provide?
A: Each of the two channels uses a Form C (C-type) relay contact. Therefore, both normally open and normally closed wiring options remain available.

Q2: Which load voltages can this relay module switch?
A: The contacts handle 24V DC or 115/230V AC loads. Additionally, each channel carries up to 2 A continuously.

Q3: Is the Schneider STBDRC3210 still available?
A: Schneider Electric has discontinued this module and replaced it with the Modicon X80 range. However, distributors may still hold remaining inventory.

Q4: Can I replace this module while the system runs?
A: Yes, the STBDRC3210 supports hot swapping with standard NIMs. This allows replacement without powering down the entire I/O station.

Q5: Which power distribution module pairs with this relay module?
A: Use the STBPDT3100 power distribution module, which supplies 24V DC field power. Alternatively, the STBPDT3105 model also offers compatible performance.
