      Description

      The Quad Signal Converter (QSC) has been designed to provide a compact Isolation, Signal Conversion, Arithmetic Processor Unit and General I/O device for process control applications.

      The QSC has four isolated inputs, four isolated analogue outputs, four relay outputs, two isolated digital inputs, RS485 (Modbus and RMF) and a USB interface for configuration.

      In its simplest form this can be used as four isolated signal converters with alarm relay outputs in one DIN rail mounting module 45 mm wide.

      Specifications
      • Four individually isolated inputs - standard types are: 0-100 mV (0-30 mV also possible), 0-1 V, 0-10 V, ±10 V, 0-100 V, 4-20 mA, 0-20 mA and loop powered 4-20 mA.
      • Two inputs can be factory configured for DC or AC currents 0-1 A, 0-5 A.
      • Input impedance > 100 kΩ for voltage input versions, 50 Ω for mA current inputs.
      • Input and output accuracy 0.1 % of ranges. Linearity better than 0.1% of full scale, basic 12 bit accuracy (0.05%).
      • Input signal status using LEDs to indicate input “normal” and high or low input levels.
      • Two output versions:
        • Four outputs – all four are 4-20 mA, loop powered.
        • Four outputs - three of which are 4-20 mA, loop powered, one is a self-powered output: 4-20 mA, 0-10 V, ±10 V, ±5 V, 0-5 V.
        • Four outputs - two of which are 4-20 mA, loop powered, two are self-powered output: 4-20 mA, 0-10 V, ±10 V, ±5 V, 0-5 V.
      • Trimpot adjustment of all outputs, each output adjustment selectable using recessed push button switches.
      • Inputs and outputs can be user configured and ranged using DIP switches.
      • Step response around 100 mS or less.
      • Four separate relay outputs, able to switch 230 VAC at 5 A. Configurable to switch on each input, can switch going high (high alarm trip) or going low (low alarm trip). Hysteresis also configurable using trimpots.
      • Two opto isolated digital inputs.
      • ModBus RS485 connection for integration into control systems will be provided in the future.
      • Isolation between inputs, outputs, power supply, communications, digital inputs and relay outputs > 1000 V, between each input > 500 V.
      • Compact, high quality, self-extinguishing polyamide enclosure. DIN rail mounting - 45 x 100 x 113 mm (width x length top to bottom x height off DIN rail).
      • Up to eight four way plug-in screw terminal connections for wire diameter 2.5 mm2.
      • All controls can be adjusted on-site using front panel trimpots.
      • In the future the unit will be able to be completely configured using the USB connection or the RS485 interface.
      • Operating temperature range -10°C to +70°C.
      • Auxiliary supply 90 -250 VAC, 50 Hz (optionally 18 to 36 VDC or 9 to 18 VDC).
      • Approximate weight 200 g.
