SEA CCT 440 Manuel D'installation Et Programmation page 28

 Verification of blower by means of hysteresis with two temperature values H and L
 Working temperature of the instrument from -20 to +60° CU
 Admitted maximum environmental humidity 90% non-condensin
 Control of data introduced during the programming phase
 Possibility to manually switch over the relays through the relay test menu
 Permanent storing of programmed values and maximum temperatures reached
 Automatic display of value and number of probe related to the hottest channel
 Storage of the maximum historical data achieved by each channel
 Dielectric strength of contacts 2500 V for 60"
 Arctic mode
Only for CCT 441
 Output RS485 Half duplex protocol MODBUS-RTU
Only for CCT 442
 Output galvanically insulated 4-20mA or 0-20 mA
 Maximum permissible impedance 500 OhmT
 Temperature range
 Scale 4-20 mA (-10°C 4 mA - 200°C 20 mA) transformation formula Iout = (T+10)/210*16 + 4
(current in mA, temperature in °C)
 Scale 0-20 mA (-10°C 0 mA - 200°C 20 mA) transformation formula Iout = (T+10)/210*20
(current in mA, temperature in °C)
