Teracom TDO340 MODBUS RTU relay output module, 4-Channel with SPST relay contacts
The MODBUS RTU relay output module, model TDO340, is a dependable 4-channel SPST device featuring independent contacts. It fully supports the MODBUS RTU protocol, enabling you to configure relay safety statuses both at startup and in the event of communication loss, ensuring continued system protection. The module is equipped with a watchdog function that detects communication failures and takes prompt action to maintain safety. Additionally, the TDO340 utilizes nonvolatile memory to retain and restore relay states following power outages. Thе device can be used as a relay output extension for MODBUS RTU master devices.
Features:
• RS-485 interface carrying up to 63 nods
• Non-volatile memory for counters storage
• LED indicator for communication status
• Watchdog functionality for communication loss
• Reinforced isolation of relay contacts
• Built-in 120 ohms termination resistor
• DIN rail mounting
• Firmware update via the interface
Applications:
• AC/DC consumers commutation
• Industrial process control
