Advantages

  • 2 independent control channels in one device
  • 2 DIN cases – horizontal and vertical
  • Universal input for 4 RTDs, 4 T/Cs, and 3 linear types
  • ON/OFF- pulse-mode control
  • RH, pH, and Δt variants available
  • RS485 serial interface available

Description

RT180 offers an exceptionally convenient and inexpensive solution for 2 loop-control applications within 1 machine or 2 adjacent ones. The universal programmable inputs make sensor change easy and convenient, and allow on-site configuring of variety of inputs and controlled physical values. The controller may be used for measurement and control of temperature difference (variant ‘D’), pH and temperature (variant ‘P’), relative humidity through the “wet-and-dry-bulb thermometer” method (variant ‘R’), and in other cases in which 1 device measures and controls 2 physical values. All of this make RT180 widely applicable for both industry and laboratory use.

(1) Instead of a chosen standard input
(2) Provides loop supply voltage – 24 VDC (only w/ isolated power supply)
(3) pH input is available ONLY for the 1st channel. The 2nd channel must be for temperature correction and/or control (Pt100: -19.9…99.9 °C).
(4) Ask for availability!
