Weidmüller ERC-1TX-4CO Relay Converter Module, 1 Digital Input, 4 Changeover Relay Outputs, 24 V DC, PUSH IN, DIN Rail

Space and wiring simplicity are paramount in industrial control cabinets. The Weidmüller ERC-1TX-4CO replaces the traditional pairing of a separate signal conditioner and a bank of relays with a single compact module. One 24 V DC digital input drives four independent changeover relay outputs, eliminating redundant components and reducing panel clutter. PUSH IN terminals allow tool-free wiring, while LED indicators provide immediate status confirmation. This module is engineered for reliable switching in demanding environments.

Highlights

• 1 digital input (24 V DC) and 4 electromechanical changeover relay outputs
• PUSH IN connection technology for fast, tool-free wiring
• Compact DIN rail TS 35 mounting for easy integration
• LED status indication for input and output states
• Wide operating temperature range from -25 °C to +60 °C
• High switching capacity: up to 6 A at 250 V AC

In daily use

Installation is straightforward: snap the module onto a standard TS 35 DIN rail, connect the 24 V DC supply and digital input using the PUSH IN terminals, and wire the relay outputs to your loads. The clear LED indicators provide immediate visual confirmation of signal presence and relay activation, reducing troubleshooting time. The module's IP20 rating suits it for control cabinets and distribution boards, while the robust relay contacts handle both AC and DC loads with confidence.
