Essential details:1769-IR6 Compact™ I/O 1769-IR6 RTD/resistance Input Module
The 1769-IR6 module receives and stores digitally converted analog data from RTDs or other resistance inputs, such as potentiometers. The module supports connections from any combination of up to 6 RTDs or other resistance inputs. See the input specifications on page 20 for supported RTD and resistance types, their associated temperature ranges, and the analog input signal ranges that each channel supports. Each of the 6 input channels is individually configurable for a specific input device and provides open- or short-circuit and over- or under-range indication.
Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution degree 2(1)) and to circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3)
The module can be attached to the controller or an adjacent I/O module before or after mounting. For mounting instructions, see “Panel Mounting” on page 6, or “DIN Rail Mounting” on page 7. To work with a system that is already mounted, see “Replacing a Single Module within a System” on page 7.
The following procedure shows you how to assemble the Compact I/O system.
1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked (fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a small screwdriver.
