The Vykon IO-16 is a compact direct I/O module for auxiliary monitoring and control when used with a JACE-2 or JACE-6 series controller (JACE-2/6) or other JACE platforms as identified in their respective datasheets. This option expands the JACE by an additional sixteen logic-controlled points. Included are eight universal inputs, four form “A” (SPST) relay outputs, and four analog (voltage only) outputs. This greatly expands the JACE’s monitoring and control capabilities with fast, reliable, direct inputs and outputs for monitoring power, temperature, humidity, and status. The on-board I/O can be used to monitor pulse contacts from power/demand meters, analog sensors, ortransducers, as well as to control energy-consuming devices such as fans, lights, or pumps with digital relay outputs. Also included are four analog outputs to proportionally control dampers, valves, and other devices. Up to four IO-16 modules may be cascaded to a JACE-2/6, to provide a total of 32 UIs, 16 relays, and 16 analog output points.
