Four Additional Outputs and Dry Contacts; +25/50 Vdc
B.10.1
General Description
This section describes an optional board with the following features: Four Additional Outputs With Dry
Contact and +25/50 Vdc. With six configurable outputs, this option includes four standard, 5 V CMOS
outputs, two Aromat AQV210E solid-state relays (SSRs).
A +25 Vdc or +50 Vdc supply is available
on-board and may be switched by the SSR outputs.
