SNAP Analog Input & Output Modules

SNAP I/O analog input modules are part of Opto 22’s SNAP PAC System. All of these modules mount on a SNAP PAC rack with a SNAP PAC brain or R-series controller, either a standard wired model or a Wired+Wireless™ model.

SNAP I/O analog output modules are also part of Opto 22’s SNAP PAC System. They mount on SNAP PAC racks along with other I/O modules and a SNAP PAC brain or R-series controller, either a standard wired or a Wired+Wireless™ model.

SNAP I/O isolated analog input modules provide two channels isolated from each other, thereby eliminating problems caused by ground loop currents. These isolated analog modules are part of Opto 22’s SNAP PAC System and mount on SNAP PAC racks with an I/O processor (brain or on-the-rack controller). SNAP isolated analog input modules are compatible with all SNAP PAC brains and rack-mounted controllers, including Wired+Wireless™ models.

SNAP pH/ORP Input Module

The SNAP-pH/ORP module provides two isolated channels of high-impedance voltage input, either -1.00 to +1.00 volts or -0.50 to +0.50 volts.

The module is ideal for differential voltage measurements and is used with pH or oxidation reduction potential (ORP) probes for monitoring bodies of water such as holding tanks, swimming pools, and cooling towers.

SNAP-AIPM Modules

The SNAP-AIPM analog input modules provide an efficient way to monitor AC voltage and current using a SNAP PAC rack-mounted controller or SNAP PAC brain.

Two models are available:

• The SNAP-AIPM monitors single-phase AC power
  
• The SNAP-AIPM-3 monitors three-phase AC power

Both modules mount on a SNAP PAC rack right alongside digital, analog, and serial SNAP I/O™ modules.

SNAP-AIPM modules help you measure and control power usage, so you can reduce costs, maintain power quality, and track energy use. If they are part of a SNAP PAC System running a PAC Control™ strategy, strategy logic can automatically perform additional calculations and respond to any problems the module reports.

SNAP Load Cell Modules

The SNAP-AILC and SNAP-AILC-2 modules each provide one channel of transformer and optically-isolated analog-to-digital conversion for load cell inputs.

These modules support 6- or 4-wire load cells (4-wire is at reduced performance). Both modules provide isolated 10 VDC bridge excitation for up to four parallel 415/350 ohm load cells as a load cell front end. For both modules, 24 VDC is required at the separate connector on top of the module.

The bridge and 10 VDC bridge power are isolated from the 24 VDC bridge source and the 5 VDC source used by the mounting rack.

The 24 VDC input is reverse-polarity protected and may be used for multiple modules. The 10 VDC bridge source is current limited so that an external fault on the load cell is isolated and will not affect another load cell module.
