It provides a switching contact relay with galvanic and safety isolation for switching 230 V/16 A power loads. The relay can respond to the status of control panel PG outputs or to the activation of devices of the JA-15x series with unidirectional communication, enrolled directly to the relay. The response can be selected from five modes – the default NATURAL function (extended copy), IMPULSE, STATUS CHANGE, SWITCH OFF and BLOCK. The relay also has a button for a direct manual status change. It allows you to update the firmware via a USB port. It is designed to be mounted on a DIN rail. It occupies one position in the system.
