The
MCOM301IO is a compact industrial I/O expansion module for PLC, SCADA, and
automation systems. It provides digital and analog inputs/outputs with
photocoupler isolation and communicates via RS485 Modbus RTU. Designed for
robust industrial performance across -25°C to +75°C, it is ideal for industrial
automation, building control, and process monitoring.
· Source-type Digital Outputs
