This is my first time I am using this keysight module and I am confused on the amount of relays this module has.
The datasheet states this has 20 form A relays. When I look D-sub connector pins it looks like each channel has 4 SPST relays. Are those relays already connected to each other and act as one or are they independent of one another. Are there any examples of how one might configure this? Thanks.
Hi, this module has 20 isolated SPST relay. For relay#1, Pin 3 and pin 19 (connected together) is for NO contact and pin 4 and 20 (connected together) is for common. We have 10 relay on 1 50 pin connectors and the last 10 relay on second 50 pin connector.
