ENDA EHTC7425A HUMIDITY AND TEMPERATURE CONTROLLER Thank you for choosing ENDA EHTC7425A Humidity and Temperature Controller 72 x 72mm sized Dual 4 digits display 0/4-20mA, 0-10V, 1- 5V analog or digital input (Specify at Order) Heating or cooling control selection PID, On-Off Temperature control selection PID Auto-calculation (SELF TUNE) Humidification or drying control selection Internal supply output for sensor Timer control for fan relay output 2 Relay outputs with time setting for incubation operations Adjustable buzzer alarm feature for measurement values CE marked according to European Norms. C(on/off) HUMIDITY TEMPERATURE CONTROLLER TECHNICAL SPECIFICATIONS ENVIRONMENTAL CONDITIONS Ambient/stroge temperature 80% Relative humidity for temperatures up to 31°C, decreasing linearly to 50% at 40°C. Rated pollution degree KEEP AWAY device from exposed to corrosive, volatile and flammable gases or liquids and DO NOT USE the device in similar hazardous locations. ELECTRICAL CHARACTERISTICS Supply Power consumption Wiring Temperature input range Humidity input range EMC Safety requirements 230V AC 110V AC ±10%, 50/60Hz or 10...30V DC / 8...24V AC Max. 7VA 2.5mm² screw-terminal connections 0~20mA / 0~10V can be selected for analog output sensors. Temperature range for digital output Enda Sensor is -40~125°C 0~20mA / 0~10V can be selected for analog output sensors. Humidity range for digital output Enda Sensor is 0~100 RH EN 61326-1: 2013 EN 61010-1: 2010 (pollution degree 2, overvoltage category II) INPUTS Input Type Measurement Range Input Resistance Approx. 10Ω Measurement Accuracy When the device is in current measurement mode, the input impedance is 10Ω. Therefore voltage input should not be connected to the device while in current mode. Otherwise the device will deteriorate. If it is necessary to switch from the voltage measurement mode to the current measurement mode while the device is running, It must be removed and then changed to one of the input type current measurement modes. OUTPUT Sensor Supply Life expectancy for relay 15VDC , Max. 50mA 30.000.000 Switching for no-load operation; 300.000 switching for 10A resistive load at 250VAC. HOUSING Housing type Dimensions Weight Enclosure Material Suitable for flush-panel mounting according to DIN 43 700. W72xH72xD97mm Approx. 350g (after packing) Self extinguishing plastics Avoid any liquid contact when the device is switched on. DO NOT clean the device with solvent (thinner, gasoline, acid etc.) and / or abrasive cleaning agents. SİSEL MÜHENDİSLİK ELEKTRONİK SAN. VE TİC. A.Ş. Şerifali Mah. Barbaros Cad.

PROGRAMMING THE DEVICE (1/2) Device has two menus as user and hidden menu. User menu is the frequently used parameters and the hidden menu is where all parameters are found. Menus can be transferred between parameters. If SET and keys are pressed together for 2 seconds in the hidden menu, the parameter is transferred to the user menu. Up to 10 parameters can be transferred to the user menu in this way. If SET and keys are pressed together for 2 seconds in the user menu, parameter is removed from user menu. User Menu If keys are pressed together for 2 seconds, user menu is entered and first...
