Relay Outputs
The PumpSmart PS220 has 3 Form C “Dry Contact” relays on board as standard. They are fully assignable to oper-
ating and fault conditions. Relays will revert to original states once warnings, faults and the operating conditions
are reset or cleared. Each can be forced on, off, and inverted. By default, Relay 1 is configured for Ready, Relay 2 is
configured for Running, and Relay 3 is configured for Fault. If they are not used, they will show “Force Off” in their
configuration status. Additional relays can be added with an extension module.
The relay outputs should be configured using the PS220 Configuration Wizard. To get to the wizard from the home
view follow the path:
Menu>PS220 Configuration>I/O Configuration>No>Relays>
Relay Output Technical Information.
Switching Capacity is 30 VDC/250VAC with max of 2 Amps.
Refer to the PS220 Wiring Diagram for detailed information on connections required.
