Bulletin 900 — Interface Converter
- Enables RS-232 or USB ¬ (ser. B or later converter) to RS-485 Communications between a Personal Computer (PC) using 900BuilderLite™ (900-TC8/ 900-TC16) or 900Builder™ (900-TC32) Software and up to 31 Bulletin 900-TCx Controllers — ideal for industrial applications
- All signal lines have 1500V AC insulation at the RS-232C (USB: 500 V AC) and RS-485 sides using opto-couples; power supply lines have 1500V AC insulation using a transformer
- Diagnostic LEDs indicate power available and active data transmission
- On-Board wiring and data configuration diagrams simplify startup
- DIN Rail or panel mountable
¬ Use of the USB mode requires the download of free software onto your PC. This software can be found at the
Bulletin 900 Temperature Controller website:

‡ With RS-485 communications, connect a terminating resistance (120W, 1/2 W recommended) to both ends of the communications link/network.
§ The Bulletin 900-TCx communications number must be set.
§ A pre-fabricated 3 m RS-232 cable with a 9-pin female D-shell connector on one end and three flying leads at the other is available from Allen-Bradley (Cat. No. 900-CP1X).
Ø RS-485 allows connecting 32 devices.
z Use a commercially available USB cable
