HUMIDITY CONTROLLERS AND TRANSMITTERS • Wall mounting bracket provided • Transmitter built into the probe housing • Adjustable or removable duct flange included • Water tight stainless steel housing • 4 to 20 mA or 0 to 1 V outputs • 0 to 100 °C operating range V_'___J The RDP series transmitters are ideal for measuring Relative Humidity (RH) and temperature in enclosures or ducts. The RDP requires a hole less than 1" in diameter and can be inserted anywhere from 1" to 9" into the enclosure. The RDP can be ordered with 4-20 mA or 0-1 V ouputs and includes a bracket for wall mounting. Relative Humidity 3 % RH to 95 % RH range at ±2 % RH accuracy. Temperature compensated -10 °F to +175 °F Temperature 0 °C to +100 °C (32 °F to +212 °F) range at ±0.6 °C (±1 °F) accuracy. RH and Temperature Outputs 4 to 20 mA or 0 to 1 V Input Voltage 6 to 30 VDC, polarity protected for both current and voltage input units Dimensions See diagram below Temperature Response Time Under 10 seconds Housing Stainless steel NEMA 4 enclosure. Duct flange 70 mm (2.75 in) dia. cutout hole 21 mm (.812 in) dia. has 4 mounting holes 4 mm (.156 in) dia. on 51 mm (2 in) circle. Wall mounting bracket also included. Weight 198 grams (7 ounces) with flange Connections 4 pin connector on 12 in. cable accepts 26 to 18 AWG wires. Mating connector included. Maximum Loop resistance at 20 mA for each output (RH and temperature); 0 D at 6 VDC, 200 D at 10 VDC, 700 D at 20 VDC, 1450 D at 30 VDC.
