PCS TRIO™ Single Dimmer/Double Pole Relay Module

- Dimmers shall be of the solid-state relay (SSR) type using silicon controlled rectifiers (SCR) arranged in an inverse parallel configuration
- A toroidal filter assembly modifies the rate of current rise ('rise time') within that circuit and operates with a rise time of 350µs
- Double Pole Relay circuits utilize mechanically latching, open-air type relays rated for 500,000 cycles
- Relays maintain last state (open or closed) until signaled or manually manipulated
- Dimmer and relay circuits possess zero-cross detection for trigger timing
- The SCR dimmer and double pole relay are mounted to a vertical PCB to increase heat dissipation
- Stacked modules within a Module Chamber utilize a 'plenum' effect to maximize cooling via convection
- Individual modules possess over-temperature sensing
