SRM8 is an 8-channel relay module designed to allow expanding microcontroller I/O pins. SRM8 is based on the 8-bit shift register 74595 IC. It supports 8 output relays while using only three I/Os. SRM8 can be daisy-chained to further extend the outputs to theoretically an infinite number while still using the same three microcontroller I/O pins. SRM8 module can be supplied from a wide range of voltages (5-40V). The input control signals are Digital Input (DI), Clock (CK), and Load (LD). Every time the shift register Clock input receives a low to high transition it accepts the data input value to bit0 and shifts the internal register data by one bit. Thus, 8 clock pulses are required to get one-byte data from the microcontroller. Finally, a latch pulse is required to load all internal shift register data to parallel outputs (Relays). This control sequence can be performed using a hardware-implemented SPI or a few lines of written code.
Features:
Supports: 8-channel output relays.
Protocol: SPI.
Wide operating voltage range: 5-40V (two selectable ranges).
Input signals (TTL): Data Input (DI), Clock (CK), and Load (LD).
Output signals (TTL): Data Output (DO), Clock (CK), and Load (LD).
Power-on relay status is OFF (a reset operation is auto-applied up on power on).
Green LED for power indication.
Red LED indicator for each output relay.
Both normal open and normal close terminals are available.
Reverse polarity protection for power input.
Input and output signals are available via screw clamp terminals as well as pin headers for flexibility.
SRM8 module can be daisy-chained to obtain a large number of relay outputs.
The power connector is duplicated to facilitate the daisy chain board-to-board power connection of up to 16 modules, To connect more SRM8 modules use external wiring.
Mounting: Four (Ø 3.5mm) mounting holes for easy installation.
