4x Analog to Digital inputs (4x 0-5VDC Input)
This module is ideal for connecting third party analogue sensors with a 0-5VDC scale output. Many
industrial sensors are available with this scale output, opening up the possibilities of monitoring many
different sensors not provided by AKCP.
4x Mini Relays
This module includes 4x mini DC relays. Use them to switch on/off low current devices directly, or use
them to drive larger relays. Ideal for systems and control, building and industrial automation. Contact
ratings : 1A 24VDC/120VAC resistive load
2x Mini Relay and 2x 0-5VDC Input
This module is a combination of the above modules: 2x relays and 2x 0-5VDC Analog sensor inputs.
Internal UPS (4x AA rechargeable batteries)
This module is an internal mini UPS backup battery. Using 4x AA rechargeable batteries (not
supplied) you can power the SPX+ for up to 30 minutes with the modem, or up to 1.5 hours without.
Maintain your monitoring and alerting capabilities even during power outages. Make sure that your
SPX+ can continue alerting even if your network and power is down by combining the mini internal
UPS with cellular data modem.

Important Note: This backup internal power supply DOES NOT protect against unstable power or
power surges, so we still highly recommend using a dedicated third party UPS between the AC power
and the SPX+ 5VDC power adapter. As a reminder damage due to unstable or power surges will void
the warranty on the units.
