ISM-1200 amplifier
PANTRONISM-1200/24VDCDIN Rail

ISM-1200

1-channel infrared amplifier with selectable manual / automatic operation and analog output. The ISM-1200 expands Pantron's ISM-series platform with selectable manual or automatic operation, 2-step transmit-frequency selection, light / dark switching selection, a floating switching output, analog output, alarm output for power-limit indication, test input, and sensor control. It is intended for long-range through-beam sensing in harsh industrial applications where robust performance and signal feedback are important.

Key Features

  • Detection range up to 55 m in through-beam applications, depending on transmitter and receiver pairing.
  • Operation mode is selectable between manual and automatic.
  • Basic transmit level is 2-fold selectable: high or low.
  • Switching behaviour is selectable between light and dark mode.
  • Transmit frequency is 2-fold selectable: 3.7 kHz or 4.3 kHz.
  • Floating semiconductor switching output is short-circuit proof.
  • Includes analog output, alarm output for power limit, test input, and sensor control.
  • DIN rail mounting to EN 60715.

Best Fit Applications

  • Long-range through-beam sensing in dirty, dusty, humid, or washdown-prone industrial environments.
  • Installations that benefit from automatic operation and analog signal feedback for setup or monitoring.
  • Industrial gates, doors, timber, paper, bulk-material, and process equipment where conventional photoelectric sensors struggle.
  • Applications that need selectable light / dark mode and frequency selection to improve adaptation to the machine environment.

Device Layout and Wiring Notes

  • Front indicators include power display (green), output status (yellow), intensity display (green), alarm display (red), and sensor error display (red).
  • Gain is adjusted at the front potentiometer, and Test / Reset is provided by the front button.
  • Separate terminals are shown for switching output, alarm output, analog output, transmitter, receiver, and test input.
  • The page-10 diagram also identifies sensor control and amplifier mode selection by 4-fold DIP-switch.
  • Designed for DIN rail installation in demanding industrial control applications.

Compared with the simpler ISM-1000 and ISM-1100 variants, the ISM-1200 adds selectable manual / automatic operation plus analog-output capability for signal feedback.
