Rackcontrol Electronic Controller with (2) SB-68 Pressure Transducers

The RCK-862 plus is an expandable electronic controller from the Rackcontrol line for application in commercial and industrial refrigeration compression plants. It can control in low and medium temperature applications with up to three suction lines and three discharge lines. In addition to controlling and monitoring, it has two independent RS-485 communication ports that can be used for remote control via Sitrad software or other equipment via MODBUS protocol.

The RCK-862 plus is capable of controlling pressure or temperature, through its 6 configurable inputs for sensors and 8 digital inputs for monitoring devices and external drivers. Its robust hardware also has eight control outputs for compressors or fans, two analog outputs for proportional control and six digital outputs (three relay outputs and three solid state type) for ON-OFF control of compressors, unloader valves and fans. Its three solid state relays can be used together with dedicated logic for controlling digital compressors of variable capacity. The RCK-862 plus is a control module that acts alone or together with expansion modules to increase the number of inputs and outputs in large systems.

Simple to operate and configure, the RCK-862 plus is equipped with an internal buzzer (audible warning), key and screens for monitoring alarms that simplify the process of monitoring and identifying faults in the refrigeration system. There is also a real-time clock (RTC) that allows you to automate commands and record the times of alarms. The USB connection can be used to upload and download configuration parameters, as well as to update the firmware.
