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 30V / 1A (use 16-22 AWG).
Order PN
DMMOD-RAM
.
SOLENOID CONNECTION MODULE:
Connects a NORMALLY CLOSED line
voltage solenoid valve to the controller. 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. Maximum
contact rating is 240VAC (50-60Hz) / 30VDC
/ 2A. Order PN
DMMOD-SOL1
.
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
DMMOD-420.
