Linking Input and Output Signals over RS-485
The ioLogik R2000 series was designed for system integrators to acquire
and control remote digital and analog devices over RS-485. Types of
digital on/off devices include proximity switches, mechanical switches,
push buttons, optical sensors, LEDs, and light switches. Types of
analog devices include pH, conductivity, temperature, humidity,
pressure, flow, actuator, and valves.The ioLogik R2000 series of
servers can work with the standard Modbus protocol. SCADA software or
the MXIO DLL library may be used to access the server.
Full Range of DI/O and AI/O Models
RS-485 is the most popular wiring standard for many industries. Now,
Moxa offers a high quality line of remote I/O server with the RS-485
interface and upgraded functions.
- Multi-functional digital I/O with DI/Event Counter and DO/Pulse
Output modes
- Multi-function analog I/O with mA/mV/Voltage modes
- Over-current and over-voltage protection
- PLC-grade I/O design that ensures accuracy and reliability during
field operation
- Remote management of firmware upgrades over RS-485 network
Independent Configuration of Multi-Functional DI/DO and
AI/AO Channels
Each input signal can be independently configured, with DI/Event
Counter modes available for digital inputs and voltage/current modes
available for analog inputs. Each digital output can be independently
configured for DO or Pulse Output mode. The analog input channels
support various signals ranging from +/-150 mV to +/-10V at 16-bit
resolution. The analog output channels support 0 to 20 mA and 4 to 20
mA @ 12-bit resolution.
