Module RS-485 Modbus RTU 4 kênh AI+2 kênh DI+2 kênh DO ICP DAS tM-AD4P2C2 CR


  • Multifunction (4 AI, 2 DI and 2 DO)
  • 2 Voltage Input Channels and 2 Current Input Channels
  • 2-channel DI Can be Used as 16-bit Counters
  • 2-channel DO Can be Used as Voltage Input Limit Alarms
  • Adjustable Sampling Rate
  • Configurable Power-on Value and Safe Value Settings
  • Dual Watchdog


The tM-DA1P1R1 is an RS-485 Interface module that offers 1 analog output channel, 1 digital input channel, and 1 relay output channel. Analog output resolution is 12-bit with an output range of 0~10V and 0~20mA. The Digital input channel is a dry contact type and provides a 16-bit counter function. The Relay output type is a Form C, and all I/O terminals provide 4 kV ESD protection and 3 kV intra-module isolation.
