WBIO-DO-R1G-16 module


Control of contactors, warning lights, etc.

Technical specifications

Contains 16 HF49FD relays [(Datasheet)] with the configuration of contacts SPST (two contacts on the relay: NO/COM).

The relays are combined into two groups of 8 pieces, each group has one common COM pin: the upper COM pin for relays K1 — K8 and the lower COM pin for relays K9 — K16. There's no connection between groups, so the first group can switch one voltage source, and the second - the other.

Rated channel current: 1 A. The module has protection against sparking of the contacts.
