Learn how to wire the Schmersal SRB301ST Safety Relay from start to finish! This step-by-step tutorial covers power wiring, dual-channel E-Stop connections, manual reset circuit, external contactor output, and feedback monitoring. 🎯 You’ll Learn: How to wire A1/A2 power supply How to connect dual-channel E-Stop inputs How to add manual reset (S12 → X2) How to drive an external safety contactor How to wire feedback monitoring 🔧 Hardware Used: Schmersal SRB301ST | 24 V DC | E-Stop 2 NC | Reset PB NO | Contactor K1 with NC aux Timestamps / Chapters 00:00 – Intro & Overview What you’ll learn: wiring a Schmersal SRB301ST safety relay step-by-step with dual-channel E-Stop, manual reset, and external contactor monitoring. 00:20 – Why This Matters A quick story about the common wiring mistake — missing the reset/feedback connection that prevents the relay from energizing. 00:45 – Components Overview SRB301ST relay, dual-channel E-Stop (2 NC contacts), reset pushbutton (NO), contactor K1 with NC feedback, and 24 V DC power supply. 01:20 – Power Wiring (A1 / A2) Connecting 24 V DC power: A1 = +24 V DC, A2 = 0 V DC. Verify the green Power LED turns ON. 02:10 – Dual-Channel E-Stop Wiring Channel 1: S11 → NC1 → S12 Channel 2: S21 → NC2 → S22 Explanation of how dual channels ensure safety redundancy. 03:20 – Manual Reset Circuit Adding the reset pushbutton between S12 and X2. Explaining manual vs automatic reset (jumper S12 → X3 for auto start). 04:10 – Output to Contactor Wiring 13–14 output to the contactor coil K1. Demonstrate relay energizing the contactor after reset. 05:30 – Feedback Monitoring Using K1’s NC aux contact in series with the reset line (S12 → K1 NC → Reset PB → X2). Explaining why the relay verifies that the contactor is truly OFF before restart. 06:40 – Live Demo • Power ON → Press Reset → K1 energizes • Press E-Stop → K1 drops • Hold Reset while releasing E-Stop → no restart (anti-tie-down) • Release and press Reset again → safe restart 08:30 – Troubleshooting Tips No output? Check: Both E-Stop channels closed Reset loop complete Feedback contact opens correctly 24 V supply polarity 09:20 – Summary & Review Recap of all connections: Power (A1/A2), Dual-Channel E-Stop (S11–S22), Manual Reset (S12–X2), Output (13–14), Feedback (K1 NC). 09:50 – Final Demo & Wrap-Up Show full working cycle again.
