ID 983

Product catalog summary

Overview: The ID 971 controllers are designed for use in normal or low temperature refrigeration units. They feature two PTC thermostatic probe inputs, with an option to select NTC via parameter, and two relay outputs for managing the compressor and defrost functions.

Defrosting Cycle: The defrost cycle can be terminated either after a set time or when the end cycle temperature is reached, as detected by a probe on the evaporator.

Display and Programming: The controller displays readings on a three-digit display with a minus sign, and the decimal point can be adjusted via parameter. A TTL connection is available for using a Copy Card for quick programming.

They are provided with two PTC thermostatic probe inputs (NTC can be selected by parameter) and two relay outputs for compressor and defrost management. The defrosting cycle may be stopped at a specified time or, using the appropriate probe placed on the evaporator, when the end cycle temperature has been reached. The value of the probe’s reading is viewed on a display by three digits and a minus sign; the decimal point reading can be set by parameter. All the versions are provided with a TTL connection in order to use Copy Card, the quick programming accessory. In addition, the 16 A compressor relay options and the buzzer are provided. These controllers are available in the 32x74 standard format and the power supply voltage is, on choice, 230 Va or 12 Va/c.
