1769 Compact I/O
Specialty I/O Modules
Specialty I/O modules are available for more application-specific needs.
1769-ASCII Serial Gateway Module
The 1769-ASCII module, a general purpose two-channel ASCII interface, provides a flexible network interface to a wide variety of RS-232, RS-485, and RS-422 ASCII devices. The module provides the communication connections to the ASCII device.
| Cat. No. | Communication Interface | Message Length, Max. | Backplane Current @ 5V | Power Supply Distance Rating |
| 1769-ASCII | RS-232, RS-422, or RS-485 | 200 characters | 500 mA | 4 modules |
1769-BOOLEAN Control Module
Use the 1769-BOOLEAN module in applications that require repeatability, such as material handling and packaging, when there is a requirement to activate an output based on an input’s transition. If the Boolean expression is true, the output is directed to the ON state. If the Boolean expression is false, the output channel is directed to the OFF state. There are four operators that you can configure as OR, AND, XOR, or none.
| Cat. No. | Number of Inputs | Number of Outputs | Voltage Category/Type, Input | Backplane Current @ 5V | Power Supply Distance Rating |
| 1769-BOOLEAN | 8 real 8 virtual |
4 | 24V DC, sinking input, sourcing output | 220 mA | 8 modules |
1769-HSC High-speed Counter Module
Use the 1769-HSC when you need:
- a counter module that is capable of reacting to high-speed input signals.
- to generate rate and time-between-pulses (pulse interval) data.
- as many as 2 channels of quadrature or 4 channels of pulse/count inputs.
| Cat. No. | Number of Inputs | Number of Outputs | Backplane Current @ 5V | External Power | Power Supply Distance Rating |
| 1769-HSC | 2 | 4 | 425 mA | 19.2...31.2V DC 100 mA @ 24V DC |

Compact I/O to PowerFlex Drives
The 1769-SMx modules provide a Compact I/O connection to PowerFlex drives.
| Cat. No. | Description | Communication Rate | Backplane Current @ 5V | Backplane Current @ 24V | Power Supply Distance Rating |
| 1769-SM1 | Compact I/O to DPI/SCANport Module connects to PowerFlex 7-class drives, other DPI-based host devices, and SCANport-based host devices such as 1305 and 1336 PLUS II drives. |
DPI: 1925 Kbps or 250 Kbps SCANport: 125 Kbps |
280 mA | 60 mA per channel supplied by the DPI/SCANport host | 6 modules¬ |
| 1769-SM2 | Compact I/O to DSI/Modbus Module connects to PowerFlex 4-class drives and to other Modbus RTU slave devices, such as PowerFlex 7-class drives with 20-COMM-H RS485 HVAC adapters. | DSI: 19.2 Kbps Modbus RTU: 300...38.4 Kbps |
350 mA | 0 mA | 4 modules |
1769-ARM Address Reserve Module
Use a 1769-ARM address reserve module to reserve module slots. After creating an I/O configuration and user program, you can remove and replace any I/O module in the system with a 1769-ARM module once you inhibit the removed module in RSLogix 5000 programming software.
| Cat. No. | Number of Inputs | Number of Outputs | Backplane Current @ 5V | Power Supply Distance Rating |
| 1769-ARM | — | — | 60 mA | 8 modules |
