Table 37. PM864 and TP830 – Technical data
Item Value
Memory • 2 MB flash PROM (firmware storage).
• 32 MB of SDRAM (27 MB available for application
program and 5 MB used for executable firmware).
Power Dissipation 6.9W typical
11.9W typical (incl. full supply to ModuleBus and CEX-
bus, see Appendix B, Power Consumption).
Current Consumption 287 mA typical (487 mA max.)
(excl. supply of ModuleBus and CEX-bus, see Appendix
B, Power Consumption).
Power Input Connector Four pin, screw connector L+, L–, SA and SB.
Power Supply
Requirements
Inputs designated L+ and L– 24 V nominal, variation
between 19.2 V DC and 30 V DC.
Redundant Power
Supply Status Inputs
Inputs designated SA, SB
• Max input voltage 30 V
• Min. input voltage for high level 15 V
• Max input voltage for low level 8 V
These inputs are status inputs. The threshold levels are
logical "0" or "1" input limits, not power fail limits.
Power Reservoir The processor unit has an internal 5ms power reservoir,
sufficient for the CPU to make a
controlled power down.
Protection Rating IP20 according to EN60529, IEC 529.
