(if you need isolated analog modules, see opto 22 form #1182.) transformer isolation prevents ground loop currents from flowing between field devices and causing noise that produces erroneous readings. ground loop currents are caused when two grounded field devices share a connection, and the ground potential at each device is different. isolation also protects sensitive control electronics from industrial field signals. important: since these analog input modules provide multiple single-ended input channels with a common reference, the channels are not isolated from each other. (see opto 22 form #1182 for isolated modules.) bipolar and unipol ar input modules most snap analog input modules are considered to be bipolar, which means the range extends equal amounts above and below zero. an example of this is the snap-aiv module, which has a range of -10 to +10 vdc. some modules are considered unipolar, which means the range starts or ends at zero. for example, the snap-aivrms module has a range of 0 to 250 vac because ac current cannot be negative. nominal range and over-range limits all snap analog input modules have a nominal range for the field signal and most support a 10% over-range limit. the nominal range is the normal range of the field signal for the module or point configuration. the over-range limit is the maximum valid field signal the module or point configuration can read outside of the nominal range. for example, the over- range limits for the snap-aiv are -11 and +11 vdc, and for the snap-aivrms, the over-range limit is 275 vac. some modules or point configurations do not support field signals outside of the nominal range. for example, points configured as temperature inputs (thermocouple, rtd, ictd) do not support over-range readings. when the field signal is outside of the over-range limits of the module, the brain will not be able to determine if the value is too high or too low, so it will return an "out of range" value of - 32768.0 over-range limits only apply to input modules. output modules are limited to their nominal ranges.

(for more information on using legacy hardware, see form #1688, the snap pac system migration technical note .) modules snap securely into place in the row of connectors on the mounting rack. each module connector has a number. analog input modules and other types of snap i/o modules are mounted on the module connectors starting at module position zero. modules require a special tool (provided) for removal. the following diagram shows part of a snap pac mounting rack. 1. place the rack so that the module connector numbers are right-side up, with zero on the left, as shown in the diagram above. (if your rack has screw connectors, the screw connectors will be at the bottom.) 2. position the module over the module connector, aligning the small slot at the base of the module with the retention bar on the rack. when positioning modules next to each other, be sure to align the male and female module keys at the tops of the modules before snapping a module into position. 3. with the module correctly aligned, push on the module to snap it into place. 4. (optional) use standard 4-40 x 1/4 truss-head phillips hold-down screws to secure both sides of each module. caution: do not over-tighten screws. 5. follow the wiring diagrams beginning on page 4 to attach modules to the devices they monitor. most modules accept 22 to 14 awg wire; the snap-aitm-8 accepts a maximum of two solid 18 awg wires. for faster, easier field wiring installation and maintenance, use snap tex cables and breakout boards. see opto 22 form #1756, the snap tex cables & breakout boards data sheet , for compatibility and specifications. modules compatible i/o processors 32-channel inputs 8-channel inputs snap-airtd-10 snap-airtd-1k snap pac r-series controllers and snap pac brains, including wired+wire- less models 4-channel inputs snap pac r-series controllers and snap pac brains, including wired+wire- less models also the following legacy brains: snap ethernet, snap simple, snap ultimate; snap-dn p-asds; snap oem 2-channel inputs (except snap- airtd-10 and snap-airtd-1k) snap pac r-series controllers and snap pac brains, including wired+wire- less models also the following legacy brains: snap ethernet, snap simple, snap ultimate; snap-dnp-asds; snap oem; serial snap brains (b3000, modbus, pro- fibus); b3000-ha; b6 module position zero module connectors processor connector retention bar
