SNAP-AOVA-8

Production Specification

The SNAP-AOVA-8 analog output module has 8 channels, each individually configurable for any one of six voltage or current output ranges.

Voltage:
0 to 5 VDC
0 to 10 VDC
-5 to +5 VDC
-10 to +10 VDC

Current:
4 to 20 mA
0 to 20 mA

The SNAP-AOVA-8 requires a 24 VDC excitation voltage brought in through the field connector on the top of the module. This voltage is internally isolated with transformer and digital data isolators, and then used to source all channels.

Because all current is sourced from within the module using the 24 VDC excitation, current outputs cannot be used with an external loop supply. Current outputs are self-sourcing and cannot be used in loops that are loop-powered or already have a self-sourcing device in the loop.

The SNAP-AOVA-8 mounts on a SNAP PAC rack alongside other I/O modules (digital, analog, and serial). This module requires a SNAP PAC brain or rack-mounted controller with firmware version R9.4b or higher. It cannot be used with legacy controllers or brains.

To wire the module, a 6-foot-long SNAP-HD-20F6 cable is required. The cable has a 20-pin connector at the module end and flying leads for wiring to field devices.
