Modbus RTU Thermocouple/Millivolt Input Module: 4 input channels

This signal conditioner is a four-channel analog input module with four discrete outputs. It filters and linearizes thermocouple inputs while providin

g isolation between input, output, power, and network circuits. Cold junction compensation and upscale/downscale sensor break detection are standard. AC and DC power sources are supported with nonpolarized, diode-coupled terminals.

  • Features
  • Ordering info
  • Self-diagnostics monitor microcontroller activity to detect operational failures (lock-up) and execute a reset to restore communication
  • Operating temperature: -25°C to +70°C (-13°F to +158°F).
  • Heavy-duty 1A solid-state relays provide dependable on/off control of industrial devices
  • Self-calibration lowers maintenance costs by reducing periodic manual calibration checks
  • Watchdog timers provide a configurable failsafe output state for use when host I/O communication is lost
  • Four-way isolation eliminates potential ground loops between power, input, output and network circuitry
  • Standard Modbus-RTU protocol with high-speed RS-485 communication (up to 115K bps)
  • 16-bit sigma-delta A/D yields 0.1°C resolution and 0.5°C measurement accuracy
  • Thermocouple linearization and sensor break detection ensure reliable measurements
  • Four discrete outputs enable local temperature limit alarms or host-controlled on/off switching
