Hammond SKTH012009230 230V Humidity & Temperature Controller

The SKTH012009230 is a humidity and temperature controller in the SKTH Series, identified in its short description as the 230V version (HUMITY & TEMP THERMOSTAT 230V). The series is designed to provide both air temperature and humidity control as well as monitoring in electrical and electronic enclosures, and is highly effective in ATMs, parking control gates, ticket dispensers and traffic control systems exposed to wide-ranging outdoor elements.

SKTH controllers independently sense relative humidity and temperature and can switch resistive and inductive loads, such as heaters or filter fans. The series specification lists a humidity setting range of 50 to 90% RH, a temperature switching difference of 2K and a humidity switching difference of 4% RH (+/- 1K at 25C (+77F) 50% RH), and a reaction time of approximately 5 seconds.

The output is a change-over relay rated 10A resistive / 1.6A inductive @ 240 VAC and 0.6 @ 60 VDC, with a maximum inrush current of AC 30 A for 10 seconds and a service life of NO/NC 30,000 cycles. The series case is light gray UL 94V-O plastic with IP20 protection, mounting on 35 mm DIN rail, and operating/storage temperature is -40 °C to 60 °C (-40 °F to 140 °F).

Series approvals are UL file E164102 / UR component / CE. The SKTH012009230 is RoHS and REACH compliant and has a shipping weight of 0.4 lb (0.18 kg). It does not appear in the series ordering table, so confirm its display scale and dimensions against the manufacturer drawing before designing it in.
