R560
Universal analogue input module
Summary
The R560 is a microprocessor controlled, communicative module with 8 analogue
inputs with variable measuring range: voltage, resistance, temperature, current
loop). The module uses a RS485 bus for communication, and can be easily
integrated in a variety of supervision and control systems.
Application
•
Building and industrial control systems
–
measuring of temperature,
pressure, and other values
Function
The module incorporates 8 analogue inputs. The input signals are processed and
multiplexed into a 16 bit A/D converter. Each input is rangeable separately (see
Technical data), and inputs can also be used as 0 to 20 mA current measurement
inputs if the corresponding DIP switch is activated.
The module communicates by means of RS485 data bus. The Modbus RTU
communication protocol ensures smooth and easy integration in a variety of control
and data acquisition systems. It connects to process stations (PLCs) directly or
through the M012 interface (RS485 to RS232 converter with galvanic isolation).
Removable connectors are used for all signals as well as for data line so that
mounting is fast and easy. The module has a DIN rail clip.
The communication circuits are protected against overvoltage and galvanically
isolated from other parts of the module. If the module is terminating the
communication bus, i.e. it is the first or last in line, a terminating 120
resistor may
be switched on by activating the BUS END switches. Two LEDs located inside of the
housing enable fast diagnostics
