SAFETY - WARNING Mains powered equipment can be extremely dangerous Electrical regulations may apply to the connection and use of this equipment. Please check before connecting. This unit must be earthed, via pin-2 on the mains connection block. DO NOT disassemble (take apart) operate or connect this equipment to the mains if damaged in any way. INTRODUCTION The GPC_3B0 "triac module" provides an easy way to connect and control 3 mains power circuits; basically 3 dimmable load blocks in one convenient package. All mains wiring connections are via a 6-way plug-in screw terminal block on one end. All control signals are connected via an RJ-45 (8P8C) plug at the other end. The triac module can be mounted using two mounting feet that form part of the plastic end-caps. The aluminium extrusion is powder-coated black and acts as a heat sink. FEATURES Small size (130mm long including connectors) Aluminium extrusion with V0 rated plastic end-caps 3 triac controlled outputs Outputs ramp up and down (soft-start) Each output capable of switching up to 6 amps at 230V AC Total triac module load up to 15 amps Full electrical isolation between input and output Control connection via RJ-45 socket on end of module Control wiring can be Cat-5, up to 30 meters in length Operates in smart and dumb modes (see description above) TO MAKE IT GO The triac module requires a DC power supply of 10V to 15V applied via the control connector in order to operate. The control signals can come from your own control circuit or simple relays or switches. The control inputs can be switched between the 10-15V DC power supply lines for simple on/off control, or driven directly from the 5V outputs of a control circuit or microcontroller. Switching the control inputs directly on or off operate the triac module in "dumb mode", providing simple on/off control with a brief ramp up at ON and ramp down at OFF. Driving the clock and data inputs from a microcontroller allows the 3 output circuits to be individually set to any level between off and full-on. This can provide full light dimming and fan or other motor speed control.
