Input/output signal introduction

1. Input signal: 4 signals(normal open dry contacts)

Diff-pressure signal input

Upper limit of outlet-water pressure

Upper limit of outlet-water pressure (internal sources backwash only)

Lower limit of outlet-water pressure (internal sources backwash only)

2. Output signal: 18 signals (3A/24V)

16 signals control the wash solenoid valves: each signal control 4

solenoid valves 24VDC.

2 signals control the valves: singlephase electric valve or solenoid

valve. At external sources back washing, the action of the output signal synchronizes with the action of the backwash valve. When the backwash

valve is ON, the inlet valve is ON, and when the backwash valve is OFF,

the inlet valve is OFF.
