The 16DA I/O’s PLC option offers 16 analog, digital, PWM, and interrupt I/O’s (8 inputs and 8 outputs). See Figure 16DA I/O’s Datasheet p2 below, for general and technical features, and input, output, and communications details.
The 16DA I/O’s PLC option provides one each of the I2C, SPI, TTL, and RS-485 (half duplex) communications services. An I2C server may have up to 127 client nodes, which allows a network with more than 7100 total relay, analog, digital, PWM, and interrupt I/O’s.
NOTE: The I2C service is switch enabled – if enabled, the interrupt/digital isolated input and one analog/digital/PWM output are no longer available for use.
NOTE: The RS-485 service is switch enabled – if enabled, two digital outputs are no longer available for use.
One input is software configurable as either interrupt or digital isolated. One input is digital isolated. Six inputs are software configurable as either analog or digital isolated.
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.
Eight outputs are digital; of these, seven are configurable as PWM, and five are configurable as analog.
NOTE The digital/PWM output voltage range is from 5 VDC to 24 VDC,
NOTE: The digital/PWM current must not exceed 70 milliamps.
NOTE: The analog voltage range is from 0 VAC to 10 VAC.
NOTE: The analog current must not exceed 20 milliamps.
