SOLENOID

220V/TAH,

110V/TAL,

0V/TC

220V/110V output terminal, connected to solenoid valve coil

Note:

1. Max. output power of internal power-frequency transformer:

15W

2. When users choose the solenoid valve with 220V coil, connect

the solenoid coil to 220V and 0V connecting terminals;

3. When users choose the solenoid valve with 110V coil, connect

the solenoid coil to 110V and 0V connecting terminals.

Each machine must be grounded, three PEs, grounding

resistance is less than 10Ω

Note: Do not connect the connecting terminal of solenoid valve to other external loads; if the power of

solenoid valve coil exceeds 15W, the power-frequency transformer inside the integrated machine will

need to be customized or connected to external 220V/110V power independently.
