Digital input module TS32 is intended for remote data acquisition from telemetry signal transducers with a dry contact output type, capable of line monitoring on each channel.

It transmits data to upstream controllers and systems according to IEC 870-5-101.

Performance data

  • 32 channels, “dry contact” type
  • Voltage on open units – 24 VDC (polarity changes to implement the line monitoring)
  • Channel operating current – 10 mA (R lines = 0)
  • Galvanic isolation – 1500 V (power/interface lines, input channels)
  • Minimum pulse time – 1 ms
  • Maximum line impedance – 300 Ω (including detector`s resistance)
  • Maximum line capacity – 0.1 μF

Main functions

  • Data input via 32 single-point signals, or 16 doublepoint signals, “dry contact” type
  • Data exchange with central controller
  • Event registration with an accuracy of up to 1 ms
  • Algorithm of protection against bouncing: debouncing – 1 ms to 10 s
  • Lights indicating line control, light indicators showing RS status of each channel, port states, power supply/module status

Additional capabilities

  • Archive with capacity for 1000 events (over all channels)
  • Monitoring of status of communication lines between the module and the detector (continuity test, SC)
  • Lights indicating line control, light indicators showing RS status of each channel, port states, power supply/module status
  • Regular self-testing of the module (measurement of a line`s operating voltage values)
  • Module`s time can be synchronized either through the central controller, or through an external
  • GPS-receiver with an accuracy of 1 ms
  • Built-in real time clock

Communication ports

2хRS-485, data rate up to 1 Mbit/s

Data transmission protocols

IEC 60870‑5‑101

Line monitoring from module to detector

The module allows to monitor a signal line to detect if it short circuits or breaks down, being equipped with special LCM terminals, installed in the immediate proximity to the signal input point (IAS contacts or relay contacts).

Power supply

  • 18–36 VDC (up to 20 ms voltage dips with a repetition period of 50 ms are allowed)
  • Reverse-polarity protection
  • Power consumption 12 W

Overall dimensions

166х104х55 mm (WхHхD)

Mounting

DIN rail

Operating temperature range

–40...+70°C
