SOYUZ RM-4 Relay Module
The SOYUZ RM-4 relay module is designed for discrete signal acquisition and control of indicators, push-buttons and contactors using relay outputs.
The SOYUZ RM-4 module is housed in an industrial enclosure and supports connection of expansion modules from the SOYUZ product line.
The module is controlled by an embedded microcontroller and communicates via the Modbus protocol operating as a slave device with configurable address.
The device provides discrete input acquisition from four inputs and transmits control signals via twelve discrete outputs for indicator control, as well as switching four relay outputs rated for 220 V loads.
