About 1794-ID2

The 1794-ID2 by Allen Bradley is an Input/output module deployed for applications that require high-speed pulse counting. It includes 2 basic inputs which also act as pulse transmitter interfaces with 4 inputs per counter (also known as optocoupled inputs). There are a variety of processes that are aided by this module, including high-speed calculations, positioning, and quantity counting. Additionally, it contains independent –ve and +ve inputs which are basically complementary and non-complementary signals.

Event triggering in the 1794-ID2 generally takes place with 1 or 2 pulse trains, each of them being individually programmable; it has an operating voltage ranging between 12 to 24 Volts DC and supports an open style enclosure with dimensions of 46 x 94 x 53 millimeters. There are 13 indicators for process identification (1 green/red and 12 yellow); this module’s interfacing capabilities work with an I/O adapter to support communication with external devices. Basic errors with this module include transmission errors, removal from the terminal base, and incorrect module insertion.

The 1794-ID2 comes with easy screw mounting and supports DIN rail mounting as well. Installation and maintenance are quite easy with proper instructions to re-assemble parts after every maintenance. Remove field-side power before inserting this module as the electric arc generated can cause damage to property or personnel. Bidirectional block transfers help communicate with the PLC processor using both read and write instructions with the DeviceNet Manager software.
