Sinotimer Mc101 Manual [repack] Jun 2026

If you are looking to or integration using this controller, could you tell me:

Correct wiring is critical for safe operation. Always disconnect power before making connections. Refer to the specific diagram on your unit's label for the most accurate pinouts.

The final pages list common issues: “Relay does not energize” (check power and trigger wiring), “Time inaccurate” (potentiometer wear or ambient temperature effect), “Chattering output” (insufficient trigger hold time). A compact table of specifications confirms electrical life (100,000 operations mechanical, 10,000 at rated load), dielectric strength (2000VAC for 1 min), and insulation resistance (>100MΩ).

Every heating system absorbs, retains, and loses heat differently. For precise temperature stability, you must run the auto-tune feature so the MC101 can calculate its own ideal P, I, and D parameters. sinotimer mc101 manual

35mm DIN Rail or Panel Mount (depending on casing style). 2. Key Interface and Button Functions

Connect to the Negative (-) DC input terminal of your SSR (usually Terminal 4 on the SSR). For Relay Output Models (MC101-R): Terminals 3, 4, and 5 act as an internal switch. Terminal 3: Normally Open (NO) contact. Terminal 4: Common (COM) contact. Terminal 5: Normally Closed (NC) contact. 3. Button Functions and Interface If you are looking to or integration using

The time range is set via a separate switch (seconds, minutes, hours). Fine adjustment uses potentiometers calibrated in % of range—a classic analog-digital hybrid. The manual provides linearity graphs and caution notes about setting accuracy (±5% of full scale).

Press the button repeatedly to move the flashing cursor to the hundreds, tens, or units digit.

Connect a bridge wire from Terminal 1 (Live) to Terminal 3 (COM) if you want to output the same voltage. If you are switching a different circuit (e.g., a 12V valve using a 220V timer), connect the external power source to Terminal 3. The final pages list common issues: “Relay does

16A Resitive (inductive loads like motors should be derated to 8A or used with a contactor). Power Consumption: < 2W. Display: Multi-segment LCD.

is part of a broader series (including MC401, MC701, MC901) that shares similar, user-friendly functionality. Key features include:

Standard 100-240V AC (50/60Hz) or 24V DC/AC (depends on version). 3. Wiring the Sinotimer MC101
