A FLEX I/O adapter module interfaces FLEX I/O modules to an I/O scanner port across a communication network. The FLEX I/O adapter module contains a built-in power supply that converts 24V DC to 5V DC for the backplane to power the FLEX I/O modules. One adapter communicates with up to eight I/O modules, allowing connection to 256 digital input/output points, or 64 analog input points/32 analog output points, or a mix to meet your needs. Conformal coated versions of standard modules have the letter K in the last position of the catalog number, before the series designation. Extreme environment versions have the letters XT in this position.

| ♠ Catalog numbers ending with (K) = Conformal Coated. ∆ Catalog numbers ending with XT = Extreme environment version. ‡ The 1794-ACNR15 and 1794-ACNR15XT adapters accept redundant ControlNet cable media. The 1794-ACN15 and 1794-ACN15K are non-redundant. § The 1794-FLA is an extended local adapter for a FlexLogix controller. ♣ Use the 1794-ASBLT Series D adapter when communicating with Classic PLC-5/15 or PLC-5/25 via Remote I/O. The 1794-ASBLT Series D adapter is a replacement for the 1794-ASB Series D adapter only when communicating with PLC-5/15 or PLC-5/25. |

DeviceNet Straight 5-pin Open Plug to 5-pin Micro Male Connector
|
The DeviceNet straight 5-pin open plug to 5-pin micro male connector can be used in place of the 5-position open style plugs for DeviceNet, making it easier to connect I/O modules to the network, as well as reducing potential for miswiring and saving wiring time.
The DeviceNet straight 5-pin open plug to 5-pin micro male connector is compatible with:
- 1734D POINTBlock I/O
- 1790 CompactBlock LDX I/O
- 1791D CompactBlock I/O
- 1794-ADN FLEX I/O DeviceNet adapter
- 1799 Embedded I/O
