M1500 PLC
The M1500 is a fourth-generation Micro-Comm controller built with the processor daughterboard
from the S4500 (32bit microprocessor). The M1500 is physically much smaller than the S4500,
having the reduced I/O count listed below:
I/O capabilities:
(4) Relay outputs
(4) Open-collector outputs (COM1 pins used for radio switching)
(8) Discrete inputs (contact closure), (2) high speed pulse, (6) low speed pulse
(4) Analog Inputs (12bit, 0-20mA or 0-5volt dip switch selectable)
(2) additional 12bit analog inputs
Temperature (0.25 to 4.75v = -50C to +150C = -58F to +302F),
System Voltage (0 to 5v = 0 to 25.5 volts)
(2) Analog Outputs (0-20mA)
(2) RS-232 communication ports
- COM1 25pin port for radio cable
- COM2 9pin port normally used for the display module and programming
(1) RS-485 communication port
- COM3 is a 4-wire RS-485 port for I/O modules or for PLC communication
