ProSoft Technology 3100-MCM Modbus Master/Slave Communication Module

Protocols: Modbus RTU, Modbus ASCII, Modbus TCP/IP. Serial ports: 2×RS-232/485 software selectable. Baud rate: 110bps to 115.2kbps. Ethernet port: 1×10/100Mbps RJ45. Power supply: 24V DC. Current draw: 300mA. Operating temperature range: -40°C to +70°C. Protection rating: IP20. Mounting: DIN rail.

Dual serial ports support independent master and slave operation simultaneously. It supports up to 128 Modbus commands per port. Built-in message prioritization and error checking improve communication reliability. Front panel status indicators show port activity and fault conditions. Configuration is performed via software or DIP switches. It supports multiple slave addresses per port.

It integrates Modbus field devices such as instruments, drives, analyzers and weigh scales into PLC systems, process control panels, SCADA systems and factory automation networks.

Serial baud rate: up to 115200bps. Ethernet throughput: 10/100Mbps. Maximum commands: 128 per serial port. Response time: <10ms. Operating temperature range: -40°C to +70°C. Vibration resistance: 2G @ 10Hz to 500Hz. Shock resistance: 30G.

Housing: UL 94 V-0 flame-retardant plastic. PCB: FR-4 glass epoxy. Connectors: gold-plated copper alloy. Serial drivers: industrial-grade transceivers.

It features compact DIN rail mount housing, front panel status LEDs, two serial connectors, Ethernet RJ45 port, terminal block power input, and integrated mounting clips.

It receives commands from the host controller over the backplane or network, translates them into Modbus protocol frames, and transmits them to field devices over serial or Ethernet links. It receives Modbus responses from field devices, validates the data, and transfers it to the host controller memory.

Mount on 35mm standard DIN rail. Connect 24V DC power supply. Wire serial devices per Modbus wiring standards. Use shielded cables for long serial runs. Configure port protocol, baud rate and slave addresses via configuration software.
