RC91 - ANALOG SETTING TEMPERATURE CONTROLLER

Product catalog summary
Description: The document describes an analog setting temperature controller, which is multi-scale, multi-probe, and multi-voltage (24 to 230Vac-dc). It features a large knob for temperature setting and a 19 LED crown for temperature display. The scale is differentiated for precise regulation. The Undecal version includes alarms or fan control, with outputs available in Octal or Undecal configurations, offering relay or SSR options.
Front Settings: The controller supports ON-OFF, PID, and OFF modes. It accepts inputs from J, K, Pt100, and PTC probes, with temperature units in °C or °F. The full range selection includes standard and optional ranges.
Features: The supply voltage ranges from 24 to 230Vac ± 10%. The controller's dimensions are specified in millimeters. Wiring diagrams are provided for installation guidance.
Technical Data: Input power varies with voltage, with precision errors of +/- 1.5% full scale. The PID precision is 250ms, and the sample time is 0.1°C. Cold junction compensation ranges from -10 to +50°C, with a warm-up time of 20 minutes. Supported probes include J, K, Pt100, and PTC KTY 81-121.
Temperature Limits: The operating temperature range is -10 to +55°C, with storage limits from -25 to +65°C.
Relay Technical Data: The electrical life is 1x105 operations, and mechanical life is 1x107 operations. The relay current rating is 8A AC1, with a voltage rating of 250 Vac. The solid-state relay output is 12 Vdc 20mA max.
Order Code: The order code specifies configurations for scale and relay type, with options for low and high scales and static or relay outputs.
