A New Addition to the Module Family:
The Retransmission Output Module is used to convert values into 1-to-5 V analog voltage or 4-to-20 mA analog current and retransmit the result. Those values can be measured or computed with the DARWIN Series or specified via the communication interface from a PC.
The input module is a 10-channel*1 small remote multiplexer that A/D-converts the measured signals minimum of every 500 ms.*2 The input signals include not only DC voltage and temperature, but also contact, power monitor, pulse, strain and DCA(mA) signals.
*1 :Power monitor modules are 2 or 6-channel.
*2 :If input modules of different measurement intervals are mixed, the resulting measurement interval is that of the longest interval input modules.

The universal input module permits measurement of DC voltages between 20 mV and 50 V, thermocouple inputs, RTD inputs, and contact signals in up to 500 ms intervals.
Other cost-effective universal input modules are available that measure data from 20 or 30 channels in 2-second intervals, and low-cost dedicated input modules that accept voltages and thermocouple outputs.

The Power monitor module receives AC voltage or current input signals and measures RMS values, active power, apparent power, reactive power, frequency, power factor and phase angle.
The maximum measurement interval (data update cycle) is 2 seconds.

The pulse input module receives TTL or contact signals from a flow or tachometer, and counts and integrates the number of pulses. The maximum measurement interval is 0.5 second and the data update cycle is one second.

The strain measurement module measures static strain, and comes in two types.
One corporates a 120 or 350 ohms bridge resistor, the other is for connecting an external bridge box. One module enables data in 10 ch to be measured, however it requires two slots worth of space. The minimum measurement interval (data update cycle) is 500 ms.

The shunt resistor (100 ohms) is pre-installed to measure the DCA signal.

You can connect subunits to a main unit over a distance of up to 500 m using a single dedicated cable. Consequently, you can greatly reduce field wiring and installation costs. For example, in the case of a 60-channel TC input, 120 wires must be connected to the main unit, but you can replace these wires by a single twisted cable.

Convenient Power to the Input Modules
By using an extension module, you can supply power to each input module directly from the main unit or subunit.

GP-IB, RS-232C, RS-422A/485 and Ethernet 10 BASE-T general-purpose interface modules are available, enabling measured data to be transferred to a PC on a real-time basis.
