REMOTE ALARM CONNECTION MODULE:
Allows
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
Rating is 1A-120V AC/DC (use 16-22 AWG). Order
PN
MOD-RAM-CM
.
SOLENOID CONNECTION MODULE:
Connects a
NORMALLY CLOSED line voltage solenoid valve
to the system. On a non-monitored system, the
solenoid 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
required, the controller can be placed into a manual
override mode allowing for the flow of water in an
alarm condition. Contact Calmag for details. Order
PN
MOD-SOL-CM.
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-CM.
ETHERNET MODULE:
Allows for all controller
functions to be connected to a computer via an
Ethernet cable.
