Texmate SC-CTR counter/ rate controller

3 independent hardware counters (quadrature, NPN, PNP, TTL or mV sensor)

This versatile counter is compatible with a range of sensors, including NPN, PNP, namur, proximity switches and rotary encoders.

It comes in a DINrail mountable case with a built-in LCD display for simple operator interface.

This controller can be scaled to suit a variety of applications, such as pulse, distance, length and difference.

Texmate SC-CTR counter/ rate controller features:

  • 0/4-20mA input (3 independent hardware counters)
  • NPN, PNP, TTL or quadrature (x1, x2, x4) sensors
  • Input signal averaging on the rate
  • Variety of applications, including pulse, distance, length and difference
  • Factory precalibrated to suit either a 0-20mA or a 4-20mA input
  • Dual display rows with customisable display sources
  • Simple, intuitive interface with scrolling text prompts
  • Security PIN protected setup and setpoint access

The Texmate NZ SC range features a broad spectrum of versatile instruments that are ideal for either stand-alone control or as an interface to a PLC.

Measuring in at 10cm high and under 5cm wide, these compact controllers are hassle-free to install, with an easy snap-on clip for a 35mm DIN rail.

Unlike many competing DIN-rail systems, they also feature a built in 2 x 8-digit LCD display for simple operator interface.

All SC units come standard with 2 relays (5A Form A), and have the option of adding 1 serial port (RS232/485) and up to 2 analogue outputs (single 4-20mA/0-10V, or dual 4-20mA for selected models).
