Description:
The 50RRA+ PLC option offers 50 I/O’s (22 inputs and 28 outputs). See Figure 50RRA+ I/O’s Datasheet p2 below, for general and technical features, and input, output, and communications details.
Communications:
All Arduino Mega-based PLCs provide: two serial TTL (UART) services; and one each of I2C, SPI, RS-232, RS-485 (half or full duplex), and Ethernet services. All Raspberry PLCs provide: two each of RS-485 (half duplex) and Ethernet services; and one each of serial TTL (UART), I2C, SPI, Bluetooth, WiFi, and CAN bus services. Raspberry PLCs also provide four USB and one micro-HDMI sockets, plus real-time clock (RTC) and a microSD socket features. An I2C server may have up to 127 client nodes, which allows a network with more than 7,100 total relay, analog, digital, PWM, and interrupt I/O’s.
NOTE: The Arduino serial 0 service is shared with the USB port, which is designed for uploading and debugging only.
Inputs:
Six inputs are software configurable as either interrupts or digital. Twelve inputs are software configurable as either analog or digital. Four inputs are digital isolated only.
NOTE: The digital and interrupt input voltage range is from 7 VDC to 24 VDC.
NOTE: The analog input voltage range is from 0 VAC to 10 VAC.
NOTE: If the M-Duino system is configured with the GPRS option, one digital/interrupt input is no longer available for use. See Figure 50RRA+ I/O’s GPRS / GSM Pinouts below.
Outputs:
Eight outputs are switch configurable as analog or digital/PWM (Pulse Width Modulation). Four outputs are digital isolated only. Sixteen outputs are relays.
NOTE: The digital/PWM output voltage range is from 5 VDC to 24 VDC, and the current limit is 70 milliamps.
NOTE: The analog voltage range is from 0 VAC to 10 VAC and the current limit is 20 milliamps.
NOTE: The relay outputs are open by default, the current limit is 5A for max 250 VAC, and the current limit is 3A for max 30 VDC.
NOTE: The PWM outputs are 5 Vdc; connecting these to components that require only 3 Vdc may damage those components.
