Model RCK-862 Plus is a versatile compressor rack controller designed for commercial and industrial refrigeration
applications. It offers comprehensive control capabilities for low and medium-temperature systems, supporting up to three suction
lines and three discharge lines.
The controller can function as a standalone unit or be integrated with up to 10 RCK 461 expansion modules, allowing for
scalability and increased input and output capacity in larger systems.

The VX-1025E Plus is a cutting-edge, patented microprocessor-based controller specifically engineered for medium and low-temperature refrigeration applications, providing precise temperature and superheat control.

Key Features:
Relay Outputs: Equipped with 4 relay outputs to manage the compressor, defrost (electrical, hot gas, or natural), evaporator fan, and an auxiliary relay that can be utilized for lighting or external alarms.
Digital Outputs: Includes digital outputs for controlling a unipolar electronic expansion valve (EEV).
Sensor Inputs: Offers 3 NTC sensor inputs for temperature, defrost, and superheat control, along with one pressure transducer input for superheat regulation.
Configurable Digital Input: Features a digital input configurable through parameters to function as a door switch, external alarm, control output deactivation, or to activate economic mode, fast freezing, or manual defrost.
Versatile Operation: Can be set up to operate solely as an "EEV driver," controlling only the electronic expansion valve and supervising the refrigeration system's superheat.
Battery Backup System: Includes a built-in battery backup system designed to close the electronic expansion valve during power outages, eliminating the need for a solenoid valve in the liquid line.
Communication Ports: Incorporates an RS-485 communication port configurable for either MODBUS-RTU or SITRAD protocols, and a TTL port, facilitating the copying or uploading of function settings using the EasyProg programming key.
The VX-1025E Plus stands out in the market with its advanced features, making it a reliable and efficient choice for refrigeration control applications. Its patented design ensures unparalleled performance and innovation.
