• 24 Vac ± 10% 50-60 Hz – 25W (optional)
• 24 Vdc ± 10% 25W (optional)
Selectable Output Voltage
• 24 Vdc
• 24 Vac
• 115 Vac
• 230 Vac
Inputs And Outputs Not Galvanically Insulated
• Enable contact (remote cleaning enable).
• Fan contact (post-cleaning).
• 4 – 20mA (dP remote reading).
The solenoid valves connected to the unit are normally closed.
The activation of a solenoid valves causes them to open and consequently let out a jet of
air.
Alarm Relay
The two alarm relays contain 2 clean contacts on terminals 4-5 and 6-7.
Maximum permitted load: 3A @ 250 Vac - 2A @ 24 Vdc, Vac.
The relays are normally closed, opens in case of alarm, and opens to the control unit off in
the absence of power.
Fuses:
1 x 1 A @ 230 Vac.
1 x 1 A @ 115 Vac.
1 x 3 A @ 24 Vac (optional).
