Input/Output Option

KEM-IO is an optional feature that can be added to any USB-enabled J-KEM temperature or vacuum controller. It allows the controller to operate other pieces of equipment based on time, temperature changes, or external events. For example, you could instruct the controller to turn on a pump when the reaction temperature reaches 100° C., or to turn off heating when the hood door is opened.

How does it work?

KEM-IO works in combination with J-KEM’s KEM-Net software. Using the software, you define how the controller responds to temperature or external events and when to turn other instruments on or off. You can add Input, Output, and Serial Channels.

Inputs – Allows the controller to detect events that occur outside of the controller. For example, a hood door opening, or a loss of cooling water, or a GC making an injection.

Outputs – Allows the controller to operate other pieces of equipment when a set of conditions is met. For example, turn on a pump when the reaction temperature reaches 100° C., or stop stirring after three hours.

Serial Channels – Allows the controller to send commands to other pieces of equipment when a set of conditions are met. For example, if an exotherm is detected, stop heating and then send a serial command to a J-KEM chiller to turn on and start cooling to -30° C. Or stir at 200 rpm while the reaction temperature is below 80° C, then change to 400 rpm when the temperature is above 80° C.

KEM-IO can also be configured for custom applications.
