Specification

Feature Description
Channel Configuration 8 independently isolated channels (channel-to-channel isolation), each configurable for different signal types
Signal Compatibility Supports Current (0‑20mA/4‑20mA), Voltage (±10V/0‑10V/0‑5V), and HART protocol communication
HART Functionality Full HART support on all channels for communication with smart field devices, enabling advanced diagnostics and parameter configuration
Conversion Precision 24-bit Sigma‑Delta ADC with an effective resolution of 17 bits (with 60Hz notch filter)
Isolation Rating Isolation between channels and between channels and the backplane, enhancing noise immunity and system reliability
Communication Model Utilizes Producer/Consumer model, compatible with Logix5000 controllers
Diagnostic Capabilities Comprehensive diagnostics including open-wire detection, under/over-range detection, overtemperature, and field power loss
Filtering Digital filtering and selectable 50/60Hz notch filters to minimize noise interference

FAQ:

1.Do the 8 channels of the 5094-IF8IH support independent configuration of signal types?

The 8 channels of 5094-IF8IH support independent configuration of signal types:

  1. Current signal: 0‑20mA or 4‑20mA (compatible with two-wire/three-wire transmitters)
  2. Voltage signal: ±10V, 0‑10V or 0‑5V
  3. HART protocol communication: All channels support HART protocol, which can communicate with intelligent field devices to achieve advanced diagnosis and parameter configuration.

2.How much electromagnetic interference can the channel-to-channel isolation design of the 5094-IF8IH resist?

  1. Isolation parameters: Channels, channels and backplane/SA power supply are all 250V AC continuous isolation, complying with IEC 60664-1 standard.
  2. Core EMC immunity indicators: electrostatic discharge (contact 6kV / air 8kV), electrical fast transient (power supply ±4kV / shielded signal ±3kV), surge (shielded port line to ground ±2kV), radio frequency radiation (10V/m) / conduction (10Vrms), power frequency noise suppression ratio 65dB (50/60Hz).
  3. Anti-interference description: Independent isolation blocks common-mode interference and ground circulation, adapting to strong interference scenarios such as inverters and motor starts and stops; combined with notch/digital filtering and standardized shielded wiring, the anti-interference effect can be further improved.

3.Are the backplane communication models of the 5094-IF8IH and 1756-IF8H consistent?

The logical communication models of 5094-IF8IH and 1756-IF8H are consistent. The physical backplane and architecture are significantly different, and they are not completely equivalent.
