Maximum Versatility

The IO9000 module allows the use of digital and analog inputs and outputs with the AS950 sampler. With the IO9000 module, the AS950 provides more input and output options than any other Hach sampler before it. For added versatility the IO9000 is available in two versions; IO9001 is available for simple applications that only require 1 high voltage relay while the IO9004 is fully loaded. See specifications for more detail.


The digital outputs can be used to indicate an alarm or an event. Analog 0/4-20 mA outputs can be used to send information to a SCADA system for parameters such as level, velocity, flow and pH. Examples of alarms and events include: sensor outside of limits (flow related, water quality related, internal temperature or ambient temperature), program started, program completed, sample being taken, bottle full (single bottle), pump running forward, pump running in reverse, pump error, distributor error, power failure, or main battery low.


Analog 0/4-20mA inputs can be used to interface third party sensors to the AS950. Once logged, the analog process measurement can be used like a Hach sensor in applications such as setpoint alarms or event-based sampling. In addition, the third party measurements can be monitored on the user interface along with Hach sensors and peripherals.


Like the digital outputs, these relay outputs are used to indicate alarms or events. The difference is that relays can be used for switching AC mains line voltage to control higher power functions. Examples for use are for a warning light or sound signal, switching a diversion valve or gate or a control signal to another machine.
