W100 Series Water Treatment Controllers

The W100W series provide an economical and reliable way to keep your cooling tower, boiler, or condensate water treatment program under control.

Features & Benefits
Benefits:
  • Large display with icon based programming makes setup easy
  • Universal sensor input provides extraordinary flexibility; the same controller can be used with almost any type of sensor needed
  • Multiple language support allows simple setup no matter where your business takes you
  • The third control relay allows the controller to be used in more places than other entry level products

Complete flexibility in the function of each relay

  • Bleed on conductivity
  • Bleed time proportional to makeup water volume
  • Boiler Blowdown on conductivity using intermittent sampling
  • Feed in proportion to bleed time
  • Feed time proportional to makeup water volume
  • Feed as a percentage of elapsed time
  • Biocide timer with pre-bleed and post-feed bleed lockout options

Optional analog (4-20 mA) output for recording, datalogging or connection to building energy management systems

Additional Notes
Specifications:
Inputs

Power 100-240 VAC, 50 or 60 Hz, 7A max - Fuse: 6.3 Amp

Digital Input Signals (2) - State-Type Electrical: Optically-isolated input. Provides isolated 9V power. Current consumption when input is closed: 2.3 mA nominal. Typical response time: <2 seconds Devices supported: Any isolated dry contact (i.e. relay, reed switch) Types: Interlock

Low Speed Counter-Type Electrical: Optically-isolated input. Provides isolated 9V power. Current consumption when input is closed: 2.3 mA nominal. 0-10Hz, 50 msec minimum pulse width Devices supported: Any device with isolated open drain, open collector, transistor or reed switch Types: Contacting Flowmeter

High-Speed Counter-Type Electrical: Optically-isolated input. Provides isolated 9V power. Current consumption when input is closed: 2.3 mA nominal. 0-500Hz, 1.00 msec minimum pulse width Devices supported: Any device with isolated open drain, open collector, transistor or reed switch Types: Paddlewheel Flowmeter


Outputs

Powered Mechanical Relays (0 or 3 model code dependent) Pre-powered on circuit board switching line voltage. 6 A (resistive), 1/8 HP (93W) per relay All three relays are fused together as one group, total current for this group must not exceed 6A

Dry contact mechanical relays (0 or 3 model code dependent) 6 A (resistive), 1/8 HP (93W) per relay Dry contact relays are not fuse protected

4 - 20 mA (0 or 1 model code dependent) Internally powered Fully isolated 600 Ohm max resistive load Resolution .0015% of span Accuracy ± 0.5% of reading

Mechanical (Controller) Enclosure: Polycarbonate Enclosure Rating: NEMA 4X (IP65) Display: 128 x 64 graphic backlit display Ambient Temperature: -4 to 131°F (-20 to 55°C) Shipping Temperature: -4 to 176°F (-20 to 80°C) Shipping weight: 22 lbs (10 kg) (approximately) varies with model

Agency Certifications Safety: UL 61010-1:2012, 3rd Edition CSA C22.2 No.61010-1:2012, 3rd Edition IEC 61010-1:2010 3rd Edition EN 61010-1:2010 3rd Edition EMC: IEC 61326-1:2012 EN 61326-1:2013

Note: For EN61000-4-6, EN61000-4-3 the controller met performance criteria B. This equipment is suitable for use in establishments other than domestic and those directly connected to a low voltage (100-240 VAC) power supply network which supplies buildings used for domestic purposes.
