TK512DC-L / Proface 4 PLC HMI Wiring Diagram Extraction
Source: Uploaded PDF
TK512DC-L Wiring Diagram (Proface 4 PLC HMI).pdf.Note: This extraction is OCR-derived from the PDF. Critical wiring should be verified against the original drawing before assembly or energizing equipment.
Identified Devices / Functional Blocks
- TK512DC-L / Proface 4 PLC HMI wiring diagram
- AC mains input terminals: L, N, E
- Fuses shown on AC line feeds
- Thermocouple input
- Fan and light outputs
- Lift UP / DOWN control outputs
- DPDT switch
- Heater connection
- Solid-state relay outputs: SSR 1, SSR 2
- Relay outputs / contacts labeled with NC, CM, NO contact groups
- Buzzer output
Extracted Terminal / Label Text
The drawing includes the following labels and terminal groupings:
- AC input / protective earth:
L,N,E - Contact banks:
NC,CM,NO - Numbered contact pairs / channels:
-8 +8,-7 +7,-6 +6,-5 +5,-4 +4,-3 +3,-2 +2,-1 +1 - Output labels:
LIGHT,FAN,BUZZER,LIFT DO,LIFT UPWN,SSR 2,SSR 1 - Relay labels:
3CM RELAY 3 - LIFT UP,4CM RELAY 4 - LIFT DOWN - Other visible labels:
3NC,6NO,5NO,MS1+,MS1-,V0+,V0-,Q1,Q0,V1+,V1-,6CM,2CM,1CM - Heater:
To Heater - DPDT switch terminals shown numbered:
1,2,3,4,5,7
Apparent Wiring Relationships
From the OCR-extracted diagram:
- AC line L appears to be fused before distribution to loads/control contacts.
- AC neutral N and earth E are shown as common supply/return/protective conductors.
- Loads shown include heater, fan, light, buzzer, and lift up/down control.
- Relay contact groups appear to switch AC line to loads.
- SSR 1 and SSR 2 are shown as heater-related outputs.
- Lift UP and Lift DOWN are associated with Relay 3 and Relay 4 contact groups.
- Thermocouple wiring is shown with polarity
+/-.
Items Requiring Manual Verification
The PDF OCR is noisy, so these details should be checked visually before schematic creation:
- Exact PLC/HMI terminal pin numbering and order.
- Which fuse protects each branch circuit.
- Whether fan, light, buzzer, lift, and heater loads are AC mains or low-voltage loads.
- Exact SSR input/output side wiring and voltage ratings.
- DPDT switch contact arrangement and how terminals 1/2/3/4/5/7 map internally.
- Thermocouple type and polarity.
- Whether
LIFT DO/LIFT UPWNare OCR errors forLIFT DOWN/LIFT UP.
Next Step
If the goal is to build a Flux schematic, the diagram should be converted into functional blocks:
- AC input/protection block
- PLC/HMI terminal block
- Heater SSR block
- Fan/light/buzzer relay-output block
- Lift up/down relay-output block
- Thermocouple input block
- Manual DPDT switch block
Before creating the schematic, confirm whether this should be a wiring reference schematic using terminal blocks and loads, or a PCB design with actual relay/SSR/connector hardware.
