Multi-channel I/O modules offer speedy connections. (Computers & plastics).
Analog input modules monitor DC current, voltage, millivolt, or thermocouple sensor inputs and provide alarm outputs if conditions exceed user-defined limits. According to the manufacturer, analog output modules are ideal for controlling a wide variety of industrial machinery. The host defines the output of DC voltage or current signals to control speed, flow, temperature, frequency, level, force, torque, intensity, and many other properties.
Microcontrollers plus optically isolated input, output, power, and network circuits increase noise/transient immunity and prevent ground loops. Status LEDs provide diagnostic feed-back and visually indicate which channels are outside their calibrated range. In addition, watchdog timer functions allow the application to define the module's fail-safe output state. The watchdog timer invokes the failsafe condition when communication between the host and module exceeds a duration specified by the application. For further security, a second hardware watchdog timer monitors the microcontroller for failed operations and automatically resets the unit.
Series 900 I/O modules are compatible with human-machine interface (HMI) software packages that support Modbus communication.
