Module RS-485 Modbus RTU 3 kênh DI + 3 kênh Relay ICP DAS tM-P3POR3 CR


  • Wet Contact, Source- or Sink-type Digital Inputs
  • PhotoMos Relay Outputs
  • photocoupler Isolation
  • No Arcing, No Bounce, and No Switching Noise
  • All DI Channels Can Be Used As 16-bit Counters
  • Configurable Power-on Value and Safe Value Settings
  • Dual Watchdog


The tM-P3POR3 provides 3 digital input channels and 3 PhotoMOS relay output channels, each of which features photocoupler isolation. All output channels are PhotoMOS relays, while the input is based on a sink- or source-type using a wire connection. All input channels can be used as 16-bit counters. There are options for configuring power-on and safe digital output values. PhotoMOS relays provide a faster response time, greater electrical endurance, and no spike. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided.
