88TV01H-E GJR2346500R1041 88TV01E 数字量输出模块 

AC 800M控制器可由外部+24V直流电源供电。这
对于许多不同类型的工厂设备，源通常是常见的，导致
连接AC 800M控制器的长电源电缆。此外，重载变化可以
导致控制器电源电压变化，因此需要采取预防措施
以防止控制器故障。
如果PM8XX电源端子处存在+24 V电压下降的风险
低于19.2 V持续1 ms以上，则必须使用储能器
动力装置。
ABB要求在以下情况下使用DC/DC转换器和额外的储能器：
使用电缆长度超过10m的外部直流电源。
对于AC 800M控制器和相关单元的冗余电源，
始终从SS8xx投票设备导出连接。参见第页的图61

The AC 800M Controller can be powered from an external +24 V DC source. This
source is often common for many different types of plant equipment, resulting in
long power cables to the AC 800M Controller. Furthermore, heavy load changes can
cause variations in controller supply voltage making it necessary to take precautions
against low voltage in order to prevent controller malfunction.
Should there be a risk that the +24 V at the PM8XX power terminals could drop
below 19.2 V for more than 1 ms, then an energy reservoir must be used for
Powering Units.
ABB requires the use of DC/DC converter and extra energy reservoir in case
external DC-supply with longer cables than 10 m is used.
For redundant power supplies to the AC 800M controller and associated units,
always derive connections from the SS8xx voting device. See Figure 61 on page
177.

Section 4 Operation
This section describes the operation of the AC 800M Controller, comprising a
PM8xx (single or redundant configuration) processor unit, together with various
optional units. For additional technical information on optional units, see Appendix
A, Hardware Units.
AC 800M Controller (PM8xx)
Equipped with Control Software, the basic PM8xx/TP830 or PM891 hardware units
mounted on the AC 800M hardware platform constitute an AC 800M Controller.
LED Indicators
See Figure 2 on page 32, for description of placement.
Table 20. PM8xx – LED Indicators
Marking Color Function
F(ault) Red Normal state – OFF
Re-start (INIT) temporarily lit F(ault).
May also be operated by software program.
R(un) Green Normal state – ON
Re-start (INIT) temporarily extinguishes
R(un). At restart press the (INIT) push button
(3 sec. or more) until R(un) flashes.
May also be operated by software program.
AC 800M Controller (PM8xx) Section 4 Operation

P(ower) Green Normal state – ON
When lit, indicates that the CPU DC/DC
converter is generating valid +5 V and +3.3 V
DC supply voltages.
No software control.
B(attery) Green Normal state – ON
Lit when internal or external battery voltage is
above 3.1 V. The LED is controlled by a
software battery voltage test(1).

PRIM(ary) Yellow Lit in single and redundant configuration.
Indicates Primary CPU in redundant
configuration. Controlled by software.
DUAL Yellow Lit when the CPU is running in redundant
configuration and synchronized state.
(1) The software performs cyclic battery voltage level tests via a dedicated LED control input. The
battery provides back-up power for both the application memory and the real time clock during
power down. The battery is either accessible via the PM8xx cover panel or externally connected
to the external battery connector. Battery voltage is checked by the software. Voltage is common
for both the internal and external battery. For this reason the internal battery should be removed
when using the external battery, since having two batteries connected in parallel will result in
greatly reduced capacity.
(2) Only for PM891
(3) Not valid for PM891
(4) Only CN1 for PM851/PM851A. Do not connect to CN2.
