12x Universal Digital I/O (20mA sink, -10V..30V)
16x Digital I/O (200mA sink, -10V..30V)

Product Summary

The 20mA sink digital I/O port consists of 12 individual TTL-compatible lines (Ch, #1...#8), each of which can be configured as: digital input bit, digital output bit, control output, clock output⁴³ . When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 32.0V and down to -16.0V.
The 200mA sink digital I/O port consists of 16 individual TTL-compatible lines (Ch#9...#24), each of which can be configured as: input or output bit⁴⁴ . When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 32.0V and down to -16.0V.

Parameter	Specifications¹⁹	Notes
Description	12 Bidirectional Digital I/O	The 20mA sink digital I/O port consists of 12 individual TTL-compatible lines (Ch, #1...#8), each of which can be configured as: digital input bit, digital output bit, control output, clock output. When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 32.0V and down to -16.0V.
