Pump Relay Boards
• Compatible with All Cabin & Chiller Controls, Including Legacy OEM
• Replaces Legacy Cruisair Pump Relays
• Supports Dual Voltage using a single circuit board
This Pump Relay (PRP) board allows control of a common seawater pump between multiple cabin or chiller controls. It can also be used to control a common chilled-water loop pump between multiple chiller controls. Separate, fully-isolated pump trigger inputs accept either 115VAC/60Hz or 230VAC/50-60Hz. The pump power source and pump output is also isolated and can be either 115VAC or 230VAC/50-60Hz.
Two models of PRP are available, one that can support up to 2 trigger inputs, and one that can support up to 6. PRPs are also available enclosed in a metal electric box.
Are these dual voltage boards?
Yes. They operate from 85 to 240 volts AC.
Will it damage the board if I mis-wire the inputs?
No. The input triggers are completely isolated from each other and the main power.
How big a pump can I run with the pump relay?
The maximum rating is 16 amps running current for the pump relay.
What if I have a bigger or 3 phase pump on the pump relay?
There is a provision for using the pump relay to drive an external contactor.
What is the minimum trigger voltage?
We recommend driving the trigger with at least 90 volts AC.
