BCD Output Module
Information
INTRODUCTION The 7054.7144 BCD Output Module is used on the 7054 and 7144 DMM, the difference in their scale lengths being catered for by a set of links on the Module pcb. A common pcb is used for both types of instrument, Solartron Part Number 70509004. The BCD Output Module provides an isolated parallel BCD output from the 7054 7144/DMM, consisting of the magnitude, and the range (in BCD code). The DMM mode is manually selected and is therefore not programmable. The BCD Output Module operates in the normal sample/print command closed loop mode, generally associated with a system incorporating a Recorder (Teleprinter, Typewriter, etc.) and its Drive Unit, or similar devices which provide the necessary TTL compatible input/output. The following equipment is recommended for use with the 7054.7144 DMM. Solartron A290 RECORDER DRIVE UNIT Provides a simple recording system, the RDU controlling the DMM and driving the desired recording device. Solartron A226 PROGRAMMER Provides the facilities of a 10 channel scanning system with high and low limit detection. Can also be supplemented by the A290 RDU. The Module provides complete isolation between the DMM and the peripheral, and removal of the BCD Output Module from the DMM has no significant affect on the latter’s performance.
