Standard Analog 28 to
140 VAC Input Module
Features
Single channel of optically-isolated voltage-to-digital
conversion
Transformer isolated from the analog power supply
Suitable for monitoring line voltage when connected
to the appropriate voltage transformer
Description
The AD15T module provides a single channel of opticallyisolated voltage-to-digital conversion with 4,000 Vrms
transient-isolation. The AD15T is transformer isolated from the
analog power supply so that it may operate with 1,500 volts
between the input terminals and analog common. The AD15T
is suitable for monitoring line voltage when connected to the

More About Opto 22
Products
Opto 22 develops and manufactures reliable, flexible, easy-touse hardware and software products for industrial automation,
energy management, remote monitoring, and data
acquisition applications.
OptoEMU Energy Management System
The easy-to-use OptoEMU Sensor monitors electrical energy
use in your facility and delivers detailed, real-time data you
can see and analyze. The Sensor can monitor energy data from
pulsing meters, electrical panels or subpanels, and equipment.
View energy data online using a software service or
incorporate the data into your control system for complete
energy management.
SNAP PAC System
Designed to simplify the typically
complex process of selecting and
applying an automation system, the
SNAP PAC System consists of four
integrated components:
SNAP PAC controllers
PAC Proj e c t
SNAP PAC brains
SNAP I/O
SNAP PAC Controllers
Programmable automation controllers (PACs) are
multifunctional, modular controllers based on open standards.
Opto 22 has been manufacturing PACs for over two decades.
The standalone SNAP PAC S-series and the rack-mounted
SNAP PAC R-series both handle a wide range of digital, analog,
and serial functions for data collection, remote monitoring,
process control, and discrete and hybrid manufacturing.
SNAP PACs are based on open Ethernet and Internet Protocol
(IP) standards, so you can build or extend a system easily,
without the expense and limitations of proprietary networks
and protocols.
PAC P rojec t S oftware Suite
Opto 22’s PAC Project Software Suite provides full-featured,
cost-effective control programming, HMI (human machine
interface) development and runtime, OPC server, and
database connectivity software for your SNAP PAC System.
Control programming includes both easy-to-learn flowcharts
and optional scripting. Commands are in plain English;
variables and I/O point names are fully descriptive.
PAC Project Basic offers control and HMI tools and is free for
download on our website, PAC Project

SNAP PAC Brains
While SNAP PAC controllers provide central control and data
distribution, SNAP PAC brains provide distributed intelligence
for I/O processing and communications. Brains offer analog,
digital, and serial functions, including thermocouple
linearization; PID loop control; and optional high-speed digital
counting (up to 20 kHz), quadrature counting, TPO, and pulse
generation and measurement.
SNAP I/O
I/O provides the local connection to sensors and equipment.
Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per
module, depending on the type of module and your needs.
Analog, digital, and serial modules are all mixed on the
same mounting rack and controlled by the same processor
(SNAP PAC brain or rack-mounted controller).

Quality
Founded in 1974, Opto 22 has established a
worldwide reputation for high-quality products. All
are made in the U.S.A. at our manufacturing
facility in Temecula, California. Because we do
no statistical testing and each part is tested
twice before leaving our factory, we can
guarantee most solid-state relays and optically
isolated I/O modules for life.
