The 16RDA I/O’s PLC option offers 14 relay, analog, digital, PWM, and interrupt I/Os (8 inputs and 6 outputs). See Figure 16RDA I/O’s Datasheet p2 below, for general and technical features, and input, output, and communications details.

Communications:

The 16RDA I/O’s PLC provides one each of the I2C, SPI, TTL, and RS-485 (half duplex only) communications services. 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 I2C service is switch enabled – if enabled, the interrupt/digital isolated input and one relay output are no longer available for use.

Inputs:

One input is software configurable as either interrupt or digital isolated. Three inputs are digital isolated. Four 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.

Outputs:

Six outputs are relays.

NOTE: The relay output voltage ranges are 7 VDC to 24 VDC, and 0 VAC to 220 VAC.
NOTE: The maximum DC current is 410 milliamps, and the maximum AC current is 5 amps.
