Product Overview
The 1794-OE4 is a Flex IO analog output module. This module features Four (4) user configurable channels that outputs 0 to 20mA, 4 to 20 mA, +/- 10VDC and 0 to 10 VDC signals. Analog output is typically used to drive modulating devices such as Variable Frequency Drives (VFD), Valves with positioner, converters, transducers, dampers, louvers and other control elements. Each input channel of this module support single-ended wire configuration without isolation.
The 1794-OE4 is compatible with most Flex IO communication adapters such as 1794-ACN15, 1794-ACNR15, 1794-AND, 1794-AENT, and 1794-AENTR. If used with a MicroLogix system, communication adapter 1794-ASB 1794-APB may be used.
This module is used with a terminal base to operate. Appropriate terminal base for this module are 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS, and 1794-TBN. During installation to terminal base, the keyswitch position should be in position at number 4.
This module has an internal analog to digital circuit (ADC) converter. It has an analog resolution of 12 bits including sign. The modules absolute accuracy is 0.133% Full Scale @ 25°C for Voltage and 0.425% Full Scale @ 25°C for Current. This module does not require calibration.
An external DC power supply is used to operate the module. It accepts a nominal Voltage supply of 24VDC with a rated range of 10.0 to 31.2 VDC. Supply Current to the module must be 320 mA @ 24V DC ; 720 mA @ 10.0V DC.
The module has a dimension of 94.0 x 94.0 x 53.3 mm or 3.7 x 3.7 x 2.1 in. It has a with built-in group diagnostic LEDs that consists of One (1) green/red power/status indicator.VIIIVThe 1794-OE4 is a high-density analog output module. It has Four (4) Voltage / Current single-ended output channels. This module belongs to the Flex IO product family that is used for Distributed IO applications.
