Overview

5094-OF8IH is an 8-channel isolated analog output module with 15V DC backplane, 35 mA maximum, Producer/Consumer communication model, communicates with Logix 5000 controller via EtherNet/IP adapter, standard DIN rail mounting (35 x 7.5 mm).

Specification

Features	Description
Channel Configuration	8 independently isolated output channels supporting single-ended connection
Signal Types	• Current: 0…20 mA, 4…20 mA (HART) • Voltage: ±10V DC, 0…10V DC, 0…5V DC
HART Support	Each channel independently supports HART 7.0 protocol, enabling communication with HART smart devices for device diagnosis and parameter configuration
Isolation Performance	• Inter-channel isolation • Isolation between system side and field side (250V continuous, basic insulation) • Isolation from SA power supply to channels/SSV and SA to FE
Diagnostic Functions	Under-range/over-range detection, open-circuit detection, connection fault detection, and HART communication status monitoring
Calibration Capabilities	Factory-calibrated with support for user calibration to improve measurement accuracy
Hot-Swap Capability	Supports RIUP (Replaceable In-Place Under Power) function, allowing module replacement with field power removed
Environmental Adaptability	Operating temperature: -40°C to +70°C, suitable for harsh industrial environments
