Expansion Modules
All controllers (with the exception of the “-E” variants), incorporate an “Infinite Expandability
Port” (IEP) which allows for expansion to the UV sensor and all other modules. Each module
(including the sensor) comes with both a male and female connection. Connect any device to
the controller and all subsequent devices are then connected into the female end of last device
added in a “daisy chain” configuration.
The following optional expansion modules are available for use on RMS UV
controllers. Contact
your authorized distributor for purchasing information.
REMOTE ALARM CONNECTION MODULE: Al-
lows for a connection to a remote device such as
a buzzer, light, alarm system, PLC, etc., via a pair
of contacts. In normal operation the OK and COM
contacts will be connected, and in a fault condition
(Low UV, Lamp fail, Power Fail), the Fault and COM
contacts will be connected. Maximum Contact Rat-
ing is 1A-120V AC/DC (use 16-22 AWG). Order PN
MOD-RAM-RMS.
SOLENOID CONNECTION MODULE: Connects a
NORMALLY CLOSED line voltage solenoid valve to
the system. On a non-monitored system, the sole-
noid will only close on a lamp failure error. On a
monitored system, the solenoid is closed when the
UV level drops below 50%. Also note that in cases
where emergency use of untreated water is re-
quired, the controller can be placed into a manual
override mode allowing for the flow of water in an
alarm condition. Order PN MOD-SOL1-RMS.
4-20 mA MODULE: Outputs a 4-20mA signal of the
UV output to a remote device such as a data logger
or computer. Order PN MOD-420-RMS.
ETHERNET MODULE: Allows for all controller func-
tions to be connected to a computer via an Ether-
net cable.
