PLC, I/O and Communications Products
ELC Series Programmable Logic Controllers
ELC Modular PLCs
Features
●
PB Base Model—
●
14 I/O (8i/6o)
●
Over 130 instructions
●
Two Modbus (ASCII/RTU)
serial ports for master/
slave communications
●
RS-485 master port with
the ability to
communicate to 31 other
devices
●
The master port can also
