The PM891 processor unit is a monolithic unit equipped with power supply and
CPU-boards, and unit termination.
The unit contains the microprocessor and RAM memory, a real-time clock, LED
indicators, INIT push button, and a Secure Digital interface.
The PM891 does not contain any internal battery.
The main function of the power supply board is to generate isolated, short circuit
proof +5 V and +3.3 V supplies, for the CPU and I/O units. The board also contains
opto-isolated RS-232C drivers / receivers for the service port.
The PM891 processor unit is grounded to the DIN rail by means of the metallic
components of the housing. The unit consists of screw terminals for power supply
(L+, L-); redundant power supply monitoring (supervision signals SA, SB); RJ45
connectors for the control network and service port; connectors for the optical
ModuleBus and the CEX-Bus. All units on the CEX-Bus are powered by the 24 V
d.c. connected to the unit. The CN1 and CN2 ports are used for connection of
Control Network. CN1 should be used in a single network. Both ports should be
used for a redundant network.
In single CPU configuration, it is possible to connect an S800 I/O cluster directly to
the built-in optical ModuleBus plug located at the lower side of the unit.
