TL;DR: P-2 for one-shot delay. Hold UP for units. Hold SET to save. sinotimer mc101 manual

• Power: Terminals 1 (AC/DC+) and 2 (common) for supply voltage (12-240VAC/DC – a wide-range switching power supply is one of the MC101’s key features).
• Trigger input: Terminal 3 (control signal, e.g., from a switch or PLC).
• Relay outputs: Terminals 4-5 (normally open, NO), 6-7 (common), 8-9 (normally closed, NC) – though the actual pin count varies slightly by revision. The manual includes connection examples for load control, contactor activation, and interfacing with logic circuits.

What is the Sinotimer MC101?

Before diving into the manual, let’s identify the device. The Sinotimer MC101 is a digital single-shot delay timer relay (often called an "on-delay" or "interval" timer). Unlike a simple mechanical timer, the MC101 uses a microcontroller to manage precise timing functions. Sinotimer MC101 is a digital PID temperature controller

Tips and Precautions

Terminal Labels: Wiring can be confusing for beginners; requires careful attention to input vs. output [16]. Verdict Save Program 1: Press PROG to lock in

Before powering on, ensure your connections match the diagram on the side of your specific unit. Power: Terminals for AC power (usually 1 & 2). Sensor: Input terminals for your thermocouple or RTD.
