1 RMBC DIN Rail Mount BCD to SSI Converter Quality System

2 Introduction This manual addendum contains information for the installation of the RMBC BCD to SSI (synchronous serial interface). The RMBC converter is designed to be used with model PMSSI, RMSSI or LDSSI display units. BCD, strobe and address input signal may be of the voltage free type s up to VDC. See "Electrical installation" chapter for requirements for various input voltage levels. The power supply is V or to VDC. The RMBC is a DIN rail mounting module and clips easily onto standard rails 35mm rails (EN500). Plug in electrical connections simplify installation and removal for service. The plug in terminals accept wires of up to.5mm INPUTS INPUTS 96 9 Model RMBC INPUTS The BCD data address and strobe correspond to display digits as shown below. i.e. digit is the right most display digit which is the least significant digit.

3 Mechanical installation The dimensions of the RMBC are shown in the diagram below. The RMBC is designed for DIN rail, horizontal mounting. The instrument snaps onto 35mm DIN standard rails (EN500). To install the unit simply clip onto the rail shown below. To remove lever the lower arm downwards as illustrated below DIMENSIONS mm INPUTS INPUTS 96 INPUTS 35mm 0mm Max. component height 35mm CLIPPING THE INSTRUMENT ONTO THE DIN RAIL AND REMOVAL FROM THE DIN RAIL To remove from DIN rail place broad bladed screwdriver under the clip lower arm and lever the arm downwards to pull the clip away from the DIN rail. Note that two clips are used on this mounting. Page 3 of 0 RMBCMAN.0

4 3 Electrical Installation The RM Rail Mount Process Module is designed for continuous operation and no power switch is fitted to the unit. It is recommended that an external switch and fuse be provided to allow the unit to be removed for servicing. The terminal blocks allow for wires of up to.5mm to be fitted. 3. bit parallel input connections Display unit settings Set disp = Addr, SEt OPER = bc RP, 5 & s RP RP RP, & input s RP LK RP LK LK, & INPUTS INPUTS 96 INPUTS Digit Digit Input circuit BCD bit input parallel connection LK Digit Digit BCD BCD RP RP Link to centre for Link to centre for voltage Page of 0 RMBCMAN.0

Power supplies Power supplies required are V or to VDC. Supplies are non isolated (common ground or ve). DC current consumption is less than 30mA. 3.9 Link settings Links LK, LK and are used to select (to at 5VDC) or (to ) for the input lines. Place the link supplied between the centre connector and if the input signals are s from a switch, relay etc. or select if voltage signals are used. 3.0 s s RP, & are fitted for use as current limiting s on all the signal input lines.

Timing for strobe and address operation. As shown below the strobe line must become active no later than 0uS from the data and address lines becoming active. The strobe must be held active up to at least 0uS before the data and address lines become inactive. When the strobe is active the input is transparent i.e. if the data changes whilst the strobe is active then the change in the data input will be passed to the output. Date will be held whilst the strobe is inactive. The strobe must be active for at least 5uS. If more than one strobe is active then more than one digit will change. In addressed operation modes the strobe input is still needed before new data can be accepted. If necessary the strobe can be tied to a permanently active state.
