Expansion Module for Electronic Controller Racks and Chillers Full Gauge RCK-461

Expansion Module for Electronic Controller for Refrigeration Racks and Full Gauge Chillers RCK-461

The RCK-461 is an input and output expansion module from the Rackontrol line, compatible with the RCK-862 plus. It is intended for applications that require a greater number of inputs and outputs than those available on the RCK-862 plus. The RCK-862 plus controller allows the connection of up to ten expansion modules, enabling the RCK line to control small, medium and large refrigeration systems. In addition, based on the concept of expansion modules, it is possible to add new controls, functionalities and features to a refrigeration system according to demand.

This module has eight digital outputs, five relay outputs and three solid state outputs, and two 0-10V analog outputs. Suitable for driving digital compressors.

It also has 6 digital and 8 analog inputs configurable for temperature (NTC) and pressure (4-20mA) sensors.

For which model/machine?

Used to expand the RCK-862 PLUS to control Compressor and Chiller Racks.
