DIN Rail mount DMX controlled 6 channel mains relay.


railSwitch provides six mains voltage relays that can be switched independently. It is housed in a high impact DIN Rail mounting case.

The control interface uses DMX512 and RDM (Remote Device Management). The RDM interface enables product configuration, including the ability to set the start address of each relay independently (see our Jump-Start hand-held programmer). RDM also allows the product to receive firmware upgrades and run diagnostics tests.

railSwitch offers a pre-set mode that enables it to run stored programmes without an active DMX controller. Other features include data loss mode (which determines what railSwitch should do in the event of loss of the DMX signal) and test mode, which is particularly useful during commissioning.

railSwitch uses electromechanical relays that are rated for 8 A at 240 VAC when switching non-inductive loads. The product can be used to drive inductive loads, or those with high inrush currents, so long as external surge protection is added. These devices stop the contacts from being damaged by arcing. Our product, Switch-Filter, is an external PTC filter suitable for this purpose. The user must also ensure that external circuit protection such as circuit breakers or fuses are connected in compliance with the local wiring regulations.

railSwitch is an elegant solution to the automation of various devices in theatre, touring and architectural markets. Applications include animatronics, fog machines, theatre practicals, cue lights and video remote control.

The product requires an external power source. We recommend PSU-24-0.75-FER Рsee PSU.
