TPMC671

16 Digital Inputs (24V) 16 Digital Outputs (24V, 0.5A)

Application Information

The TPMC671 is a standard single-width 32 bit PMC with

16 24V digital inputs galvanically isolated from the

computer system by optocoupler. The inputs are also

potential free to each other. A high performance input

circuit ensures a defined switching point and polarization

protection against confusing the pole. All inputs have a

common

electronic

debounce

circuit

with

a

freely

programmable debounce time. All inputs can generate an

interrupt. The signal edge handling is programmable to

interrupt on rising, falling or both edges of the input signal.

The TPMC671 has 16 digital high side or low side

switches (build option) with galvanic isolation from the

computer system by optocoupler. The outputs are also

isolated against each other in groups of four outputs. All

outputs are protected against short-circuit and thermal

overload. The output drivers are capable of driving 0.5A

continuous per channel. A hardware watchdog clears all

outputs in case of trigger fail. The TPMC671-1xR provides

front panel I/O, the TPMC671-2xR provides P14 I/O.

Software

Support

(TDRV003-SW-xx)

for

different

operating systems is available.
