Part Number: The main communication gateway module is 136180-01 and the I/O module is 136188-02 for interfacing with external systems.
I/O Module Type: 04 for Ethernet / RS485 Modbus I/O Module.
Memory type: 01 indicates low memory.
Communication protocol: support Modbus RTU protocol through RS-232/RS-422/RS-485, which can be integrated with PLC, DCS and other control systems; Supports Ethernet communication for remote monitoring or integration with network-based control systems; Modbus TCP/IP protocol is also available for high-speed data transfer.
Communication mode: Support half-duplex and full-duplex communication mode, flexible configuration.
Ethernet interface: The Ethernet connection is an RJ45 interface for 10Base-T radial configuration Ethernet networks.
Power consumption: Typical power consumption is 5.0 watts when using Modbus RS-232/RS422 I/O modules; When using the Modbus RS485 I/O module, the typical power consumption is 5.6 watts.
Indicators: The OK indicator is used to show if the module is operating properly, and the TX/RX indicator is used to show if the module is communicating with other modules in the 3500 rack.
Operating pressure dependent: For installations in accordance with N.F.P.A. 495 - 1982, static purge pressures greater than 0.05 kPa (0.2 inches of water) for installations that meet N.F.P.A. 495 - 1982 specifications; For installations that comply with the Canadian Electrical Code C22.1 - 1986, pressures must be greater than 0.25 kPa (1.0 inches of water). The maximum operating pressure should not exceed 2.49 kPa (10 inches of water).
