10.1 Expansion modules
BWT controllers incorporate an “Infinite Expanda
-
bility 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 the last device
added in a “daisy chain” configuration.
The optional expansion modules are available for
use on all BWT controllers. Contact your authorized
distributor for purchasing information.
10.2 Remote alarm connection module
Allows 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).
10.3 4-20 mA module (option)
Outputs a 4-20 mA signal of the UV output to a
remote device such as a data logger or computer.
