This is compared to anadjustable setpoint to provide either a currentoutput or VFC switched output.FEATURES■■Reliable and accurate switching■■VFC or current output■■Quick and simple to installSPECIFICATIONOutput: Current mode (dry 12 mA)VFC mode SPDT contact, 240Vac @ 1A resistiveSupply voltage: 24Vdc ±5% or 24Vac ±10%Cable:Low smoke and fumeDimensions: 70 x 48 x 30mm (2.76 x 1.89 x 1.18”)Weight:80g (0.18 lb)Part code DescriptionWD-CPS Condensation Detector - 2m (6.56 ft) leadWD-CPS-5M Condensation Detector - 5m (16.4 ft) leadData sheet: WD-CPS.pdfAir & Water Flow Air Quality & Gas Detection Controllers Input / Output Modules Water & Energy Metering Peripherals70www.sontay.com · Email sales@sontay.com
