8- or 16-Relay Back Panel
Orange Traffic manufactures 8- or 16-relay back panels for mounting in distribution and control enclosures.General characteristics
Description
Orange Traffic’s distribution panel—or back panel (term used by the Ministère des Transports du Québec)—houses the load and transfer relays, bus interface unit, flashing light, light signal connection terminal blocks and detection cabinet. It distributes a filtered voltage of 120 V to the light signals as instructed by the control unit.
Six dummy dynamic loads are mounted on the front of the panel for easy access. These loads neither draw energy nor produce heat, contrary to the power resistances that are normally used.
The distribution panel is mounted on sliding hinges to allow it to swing forward freely, providing easy access to the back. The light connection terminals’ raised and forward position greatly eases and simplifies onsite electrical connections.
