TPMC671 16 Insulated Digital 24V Inputs and 16 Insulated Digital 24V Outputs with High-/Low-Side Switching

The TPMC671 is a single-width 32 bit PMC with 16 insulated digital 24V inputs. The input circuit ensures a defined switching point and polarization protection. All inputs have a common electronic debounce circuit with a freely programmable debounce time and can generate interrupts. The signal edge handling is programmable to interrupt on rising, falling or both edges.

The TPMC671 has 16 digital high side (TPMC671-10/20) or low side (TPMC671-11/21) switches with insulation in groups of four outputs. All outputs are protected against short-circuit and thermal overload. The drivers are capable of driving 0.5A continuous per channel. A hardware watchdog clears all outputs in case of trigger fail. The TPMC671-1x provides front panel I/O and the TPMC671-2x P14 I/O.

Drivers are available for Linux, Integrity, QNX, VxWorks, and Windows.
