EWDR products, available in 4 DIN rail-mounting size (70x85mm), are designed for applications that require the mounting of controllers on DIN rails, like electric boards for cells or, more generally, for applications with centralized electric board.
This line of products has been specifically designed by Eliwell to meet all the needs of customers working in the commercial refrigeration sector.
230Vac power supply
EWDR 983: two digital relay outputs
EWDR 985: four digital relay outputs
EWDR 983 controller has two voltage-free digital relay outputs for the compressor and defrost.
EWDR 985 controller has four voltage-free digital relay outputs to control the compressor, defrost cycle, lights and fans of the evaporator, or one auxiliary ON-OFF light output.
The controller also has a 12V-20mA output to manage additional loads like alarms.
The three analog inputs are used for temperature control, defrost and display purposes (or for the defrost of the second evaporator).
The defrost cycle may be time-terminated or terminated by the special probe on the evaporator when the end cycle temperature is reached.
The value read by the probe is displayed with three digits plus the minus sign. Reading with a decimal point is parameter-programmable.
The buzzer is optional.
All versions have a TTL connection to allow the use of the Copy Card quick programming accessory.
/CS LX models also have:
An internal clock (RTC) for the management of defrost operations
An optoisolated RS 485 internal connector for the connection to TelevisSystem
/CSK LX models also have:
Link Master/Slave network for the management of weekly and daily defrost
All models have two voltage-free programmable digital inputs.
