5.2Parameters of digital Inputs and Outputs

The card contains eight digital TTL outputs (OUT1-OUT8) with a maximum permissible current of 20 mA at both levels. The first four outputs are also designed as relay contacts (OUT1S1/OUT1S2- OUT4S1/OUT4S2).

The maximum permissible current is 100 mA, the maximum-switched voltage is 100 V and the contact resistance is 150 mΩ. The relay is onstate (closed) when there is a LOW level of a relevant digital output.

The card contains 4 digital inputs IN1 to IN4.

To suppress contact bouncing the digital inputs are equipped with monostable toggles that prolong any change affecting the input to at least 200 ms (to ensure that the station is able to detect it).

A pulse with duration of at least 1 ms is necessary in order to excite the toggles.
