Four Channel Override Relay Module – IORM04

The IOMR4 is designed for applications that require an independent manual override of digital output channels from BMS Controllers. The outputs can be switched without a controller present, making the IOMR4 useful for temporary control or commissioning. Link selection enables up to 4 outputs to be switched from Input 1. High-Quality Rising Clamp Terminals are used for all connections. The IOMR4 is powered by 24V ac or dc and features an LED indication of Power ON and an LED indication for each energised relay. The IOMR4 is designed to mount on the TS35 DIN Rail section.
