Fisher Controller & Instrument Corp

General Purpose Digital Controller

  • A cost‑effective, microprocessor‑based single‑loop controller for temperature, pressure, and flow regulation. Available in multiple DIN sizes with RS485 Modbus RTU communication, it is purpose‑built for panel‑mount installation in industrial process control systems.

Overview

  • A versatile digital controller designed for reliable single‑loop process regulation in standard industrial environments. Suitable for installation in control panels across upstream, midstream, and downstream oil & gas facilities, it delivers dependable performance for temperature, pressure, and flow applications.

Control & Performance

  • Supports PID, On/Off, Heat/Cool (dual PID sets), Motor Position, Phase Angle, and Zero Crossover algorithms.
  • Autotuning function simplifies commissioning and enhances process stability.
  • Operates in both manual and automatic modes, with remote setpoint capability for flexible integration.

Input / Output

  • Accepts thermocouple (J, K), RTD, and high‑level analogue inputs.
  • Dual 4‑digit displays: upper for process variable (PV), lower for setpoint (SP).
  • Relay output for On/Off switching control

Communication & Connectivity

  • RS232 or RS485 interface with Modbus RTU / ASCII protocol.
  • Supports up to 30 controllers on a single host network.

Mechanical & Compliance

  • Compact ¼ DIN panel mount design (also available in 1/16, 1/8, and 3/16 DIN formats).
  • IP65 enclosure rating for durability in harsh industrial environments.
