Signal Relay click Signal Relay click Signal Relay click Signal Relay click IC/Module PCB GV5-1 datasheet [1] Interface AN, RST, CS and PWM Power supply 5V Product page [2] Schematic Signal Relay click schematic [3] Signal Relay click carries four ultra-small GV5-1 PCB relays from Omron and runs on a 5V power supply. The click communicates with the target MCU over the following mikroBUS pins AN, RST, CS and PWM. Features and usage notes Maximum continuous current The relay contacts are designed for a maximum of 1A of continuous current. The Signal Relay click board is configured so that the switch circuit supply a maximum of 24VAC/30VDC voltage of a power supply source. Each GV5-1 relay has its own LED on the board that signalizes whether the relays is switched on or off. Application ON/OFF control in various home automation devices, like alarm units, lamps, heaters, etc. It can also be used for energizing coils of bigger relays and contactors in industrial AC schemes 12/24V . Signal Relay click Key features • GV5-1 relay • Power switching from 1 mA to 1 A • 150 mW nominal coil power consumption • Maximum contact resistance 100 mΩ • 4 pairs of screw terminals • Interface AN, RST, CS and PWM pin • 5V power supply Pinout diagram This table shows how the pinout on Signal Relay click corresponds to the pinout on the mikroBUS socket the latter shown in the two middle columns .
