The TB1100 is a DB9F-to-terminal block adaptor. Housed in an attractive ABS enclosure and featuring nine screwless terminal blocks, the TB1100 is an ideal companion for our programmable serial controllers and device servers. The TB1100 directly connects nine pins of the DB9 to nine terminal blocks.
The TB1100 comes in two versions, "A" and "B", which differ in the orientation of the DB9 connector. The DB9 on the "A" version has the "wide side up" orientation ("normal" orientation). The connector is rotated "wide side down" on the "B" version.
