1794 FLEX I/O

Specialty I/O Modules

Conformal coated versions of standard modules have the letter K in the last position of the catalog number, before the series designation.

FLEX Counter I/O Modules

Cat. No.z	Number of Inputs/Outputs	Input Frequency, Max.	External DC Supply Current, Nom.	Power Dissipation, Max.	Terminal Base Unit¬
1794-IJ2 1794-IJ2K	• Inputs: 2 frequency inputs, 2 gate inputs • Outputs: 2 outputs	1…32 kHz w/sine wave; 1…32 kHz w/square wave input	220 mA @ 19.2V DC; 180 mA @ 24V DC; 140 mA @ 31.2V DC	4.6 W @ 31.2V DC	1794-TB3G, 1794-TB3GS
	The 24V DC 2 Input Frequency Module performs high-speed frequency algorithms and is capable of reporting frequency, acceleration, and direction. The frequency inputs are capable of accepting frequencies up to 32 kHz. Input devices range from magnetic pickup to flowmeters, to incremental encoders to proximity detectors. The module accepts and returns binary data. Outputs are activated by alarms. Module power is supplied from the external power supply. All power for input devices (24V DC) is supplied by the I/O module.
1794-VHSC§	• Inputs: 2 groups of A/A, B/B, and Z/Z pairs with 5V DC or 15…24V DC terminations • Outputs: 2 groups of 2	1.0 MHz counter and encoder X1 (no filters) 500 kHz encoder X2 (no filters) 250 kHz encoder X4 (no filters)	100 mA @ 24V DCT	5 W @ 31.2V DC	1794-TB3G, 1794-TB3GS‡
	The 24V DC 2 Channel Very High Speed Counter Module has two incremental quadrature encoder interfaces each with three inputs (A, B, and Z). Each input module has ±inputs for connection to pulse transmitters with complementary or non-complementary signals. The counter can count pulses of one or two pulse trains for up/down counting and detection of a selectable number of edges (X1, X2, X4). Each of the two counters has an upper limit of 1MHz, a 24-bit counter register, a preset register, and a latch register. Module power is supplied from an external 24V power supply. The 1794-VHSC has two outputs that can be configured for overlapping, multiple windows, and/or pulse width modulation. Use with 1794-ACN15 or 1794-ACNR15 Series B or later ControlNet adapters or 1794-AENT EtherNet/IP adapter.
1794-ID2	• Inputs: 2  (2 groups of A, B, Z, G inputs)	100 kHz	150 mA @ 12V DC 75 mA @ 24V DC	5 W @ 26.4V DC	1794-TB3, 1794-TB3S, 1794-TBN, 1794-TBNF§
	The 24V DC 2 Input Pulse Counter Module performs high-speed scaling, calculation operations for various industrial applications including quantity counting, speed calculation, and flow monitoring. All input devices for the pulse counter module should be able to provide the input signal of 6V amplitude.
1794-IP4	• Inputs: 4  (2 groups of 2)	100 kHz	150 mA @ 12V DC 75 mA @ 24V DC	5 W @ 26.4V DC	1794-TB3, 1794-TB3S, 1794-TBN, 1794-TBNF§
	The 12/24V DC 4 Input Pulse Counter Module performs high-speed scaling, calculation operations for various industrial applications. Typical applications include quantity counting, speed calculation, and flow monitoring. All the input devices for the pulse counter module should be able to provide the input signal of 6V amplitude. The 1794-IP4 has a 6V minimum threshold for an input On condition and a maximum 3V threshold for an input Off condition. The region between 3V and 6V is a transitional one and therefore requires input signals to pass cleanly through that region, otherwise module operation cannot be guaranteed.
z Catalog numbers ending with (K) = Conformal Coated. § As of FlexLogix firmware revision 11, you can install the 1794-VHSC module (and any other module that uses extended data transfers) on the local or extended-local DIN rails of a FlexLogix system. Previous revisions of the controller firmware support these modules only as remote ControlNet I/O. ¬ Recommended terminal base is in bold text. T Does not represent power required to supply the inputs or outputs. ‡ For use with 1794-ACN15, 1794-ANCR15, and 1794-AENT only. § Auxiliary terminal strips are required when using the 1794-TBN or 1794-TBNF for this catalog number.

SCANport Communication Module

The SCANport Communication Module interfaces two SCANport communication ports to the backplane. Each port can interface a SCANport-enabled drive or power product through an I/O adapter module to a ControlNet, DeviceNet, or Universal Remote I/O link. SCANport communication provides data for logic command/feedback, analog reference/feedback, and channel enable/status.

SCANport-enabled products include: 1305 AC Drives, 1336 PLUS AC Drives, 1336 PLUS II AC Drives, 1336 IMPACT AC Drives, 1336 FORCE AC Drives, 1336 SPIDER AC Drives, 1336 REGEN package, 1397 DC Drives, 1557 Medium Voltage AC Drives, 1394 Motion Systems, SMC Dialog Plus, SMP Smart Motor Protector, and 2364 Regenerative DC Bus Supply Unit.
