Using WAGO I/O with SMLC

WAGO Ethernet and Profibus DP I/O feature a wide variety of analog and digital I/O modules that reliably interface the ServoWire Motion & Logic Controller (SMLC) to industrial devices such as switches, sensors, solenoids, valves and motor starters.

WAGO I/O utilizes either a Ethernet or Profibus DP Fieldbus Coupler for each node, which is connected to DIN rail mounted I/O modules. The user can select appropriate modules (AC In/Out, DC In/Out, sinking/sourcing, Analog current/ voltage, etc.) for their specific application.

The WAGO Fieldbus Couplers are compact, flexible, high-performance processors that provide the interface between the I/O modules and either a Profibus DP or dedicated Ethernet network. DIN rail mounted modules provide an efficient method for mounting that minimizes panel space.

The 24 VDC digital input modules include built-in noise filters, available with either a 3.0 or 0.2 msec time constant. The AC digital output modules utilize zero voltage turn-on and zero current turn-off of the load to greatly reduce generated EMI and RFI, and feature an internal dv/dt snubber network for protection from voltage transients on the line. All digital I/O modules feature internal LED indicators and digital output modules include electronic short-circuit protection.

The analog input modules are available with 12 or 16-bit resolution, and support a variety of input signal current and voltage levels, including 0-20 mA, 4-20 mA, +/-10 V and 0-10V. Analog input modules are also available for use as interfaces to thermocouples, RTD sensors and resistor bridges. The analog output modules are 12-bit, and also support a variety of signal types.

Specialty modules are available with up/down counters, incremental encoder interfaces, SSI interfaces and more.

The I/O modules are color-coded by function and provide a high degree of isolation and noise immunity between the motion controller and external components. Optional labeling components are available to clearly indicate I/O point number, power and ground connections for easier installation and maintenance.

WAGO I/O: At a Glance

• Standard Connectivity Solutions – WAGO Ethernet and Profibus DP I/O provide standard connectivity solutions for interfacing digital and analog I/O to the ServoWire Motion & Logic Controllers (SMLCs) that is easy to implement, operate and maintain.

• Flexible Interface – All WAGO I/O modules connect to the SMLC using a Fieldbus Coupler, one per rack. The Fieldbus Coupler interfaces to the Ethernet or Profibus DP network providing a high-speed connection to all I/O in the rack. I/O can be remotely distributed throughout the machine.

• Quick and Reliable Installation – Each module incorporates CAGE CLAMP connection system for vibration-proof, fast and maintenance-free wiring with test points for easy access to signals with wiring in place.

• Digital I/O Modules – WAGO I/O provides a full line of digital I/O modules. DC inputs (5 & 24 VDC), DC outputs (5 & 24 VDC), AC inputs (80 to 230 VAC) and AC outputs (60 to 230 VAC) provide flexible interface options. Digital modules feature compact 2, 4 and 8 channel designs.

• Analog I/O Modules – Analog voltage inputs range from 0 to 10 volts, +/- 10 volts, and 4-20 mA. Analog output modules provide 0 to 10 volts, +/- 10 volts ranges. Analog input modules are available as efficient 2- channel devices. Interface to temperature sensors, load cells, dancer control systems, and other industrial analog voltage or current control points.

• Minimum Panel Space – Compact 12 mm (0.47 in) and 24 mm (0.94 in) wide, DIN rail mounted module designs allow the OEM designer to use a minimum amount of panel space.
