General Hardware Characteristics
Hardware Characteristics
On-board CPU, memory, fixed I/O
circuitry, and power supply
16 MHz CPU speed for handling I/O
throughput
A built-in time-of-day clock
A parallel expansion port for up to
three racks of A120 I/O modules
24 VDC high-speed inputs that can
be configured to operate as dedi-
cated hardware interrupts and/or a
user-configurable counter/timer/inter-
rupt input
Two RS-232 ports, comm 1 and
comm 2, for communication with pro-
gramming devices and with ASCII in-
put/display devices
Comm 2 of 61204 (only) supports
Modbus master XMIT block. Default
condition is slave. XMIT enabled
permits port to be temporary Modbus
master ASCII or RTU mode.
Comm 1 or Comm 2 of 512xx and
612xx supports comm block, which is
Modbus master ASCII only.
An RS-485 port for serial I/O expan-
sion with other Modicon Micro PLCs
The 612 models also support four
analog input channels and two analog
output channels.
The AC units (Models 51201 and
51202) have an on-board 24 VDC pow-
er supply that provides 150 mA. This
supply is suitable for driving the hard-
ware interrupts or the 24 VDC I/O
points in an AC environment.
