3-channel Isolated Digital Input and 3-channel PhotoMOS Relay Output Module
  • PhotoMos Relay Outputs
  • Source- or Sink-type Digital Inputs
  • Photocouple Isolation
  • No Arcing, No Bounce, and No Switching Noise
  • All DI Channels Can Be Used As 16-bit Counters
  • Dual Watchdog
  • Configurable Power-on Value Settings
  • Configurable Safe Value Settings
  • Wide Operating Temperature Range: -25 ~ +75°C
Model: tM-P3POR3    
The tM-P3POR3 provides 3 digital input channels and 3 PhotoMOS relay output channels, each of which features photocouple isolation. All output channels are PhotoMOS relays, while 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.
