PCT-7424C, PCT-7424E

The PCT-7424C/E card combines a high number of counters with digital inputs and digital outputs.

The card provides a 24-bit digital input port, which is connected to set of 32-bit counters. The counters can be started/stopped simultaneously and can be also reset.

The counters are expanded by one 8-bit digital input port and two 8-bit output ports.

The card also includes IRQ logic with one source derived from the internal timer. The timer allows the user (together with the period setup, startup and stop) to read back its actual state.

Counter inputs are accessible via D-Sub 25 connector, first digital output port via D-Sub 25 connector; both of them are placed on the card mounting bracket. Next two digital ports are accessible via the PCE-16xx series adaptor (not included), using the card mounting bracket with two D-Sub 25 or D-Sub 9 connectors.

PCT-7424C/E card is based on FPGA configured from on-board flash memory with user-friendly firmware upgrade.

PCT-7424C/E diferences

Isolation of counter inputs at PCT-7424E is the only diference between both version.
