The ECIO2 multiple I/O compact module contains I/O mix optimized for HVAC and home control applications. The module uses Ethernet (Modbus TCP) for communication with PLC, and RS485 (Modbus RTU) bus as link to optional extension RS485 I/O modules, and can be easily integrated in a variety of supervision and control systems.
Modbus RTU, Modbus TCP
The ECIO2 module is a multiple I/O module (8 AI, 6 AO, 8 DI, 8 DO). The module communicates as Modbus TCP station (slave) over the Ethernet interface; as web server over the Ethernet interface for IP configuration and statistics; as Modbus RTU router over the RS485 bus. Communication circuits are protected against overvoltage and optically separated. Power: 12...24 V AC/DC, Analog Inputs: 8x 0-10 V DC, measured ranges: Pt1000, Pt100, Ni1000, resistance 20..1600 Ohm, 0...5000 Ohm, optional switch-on 125 Ohm resistor for (0) 4...20 mA at AI1 to AI4, 16 bit resolution. Analog Outputs: 6x 0-10 V DC, 2x common terminal AOGND, galvanically separated 1 kV from the rest of the module, 10 bit resolution, output impedance < 16 Ohm. Analog output load min. 10 kOhm, max. current 50mA, short-circuit-proof outputs ? current limitation to 80 mA. Digital Inputs 8x 24V AC/DC ? input current 4 mA, voltage must be applied e.g. from module powering terminals (no dry contacts). Digital Outputs: 6x NO relay: 3A/250VAC, 3A/30VDC, 750VA, 90W, 2x change-over relay: 8A/250VAC, 8A/24VDC, 2000VA, 192W.
