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.

Features:
8-channel analog input for mV, voltage, current signal with wire-off detection (at 4 to 20 mA)
2-channel analog output for voltage, current actuator control
16-bit resolution analog input, 12-bit resolution analog output
Easy-to-use, quick programming lib for VB, VC++, BCB
NIST-Traceability calibration for analog I/O channels
