Product Short Description
Product Name: Shark XL Series 8-Channel, 8-Bit Analog Input Module
Product Introduction: A classic analog input module for the Reliance Electric Shark XL PLC system. It acquires 0–10 VDC voltage signals from field transmitters and sensors, converting them to digital values for the PLC processor.
Description
Technical Specifications:

Functional Features:
-
High channel density (8 channels in one compact module).
-
8-bit resolution with 1 ms conversion time for fast, reasonably accurate data acquisition.
-
High 100 kΩ input impedance minimizes loading on source signals.
-
Plug-in PCB design for easy insertion/removal in the Shark XL rack.
-
LEDs for channel status and fault indication (typically).
Application Scenarios: Temperature, pressure, level and similar slow-changing process variable monitoring in legacy industrial systems, particularly in industries still operating Reliance Shark XL PLCs (metallurgy, paper, power, manufacturing).
Working Principle: Each channel’s 0–10 VDC analog voltage is sampled by an 8-bit ADC. The digitized value is placed on the rack backplane for the processor to read. The module draws power and communication from the backplane.
Installation Requirements:
-
Insert the module PCB directly into a vacant slot of a compatible Shark XL controller rack.
-
Ensure the rack provides proper backplane power and communication.
-
Secure the module with the rack’s card-retention mechanism.
Usage Precautions:
-
The module is non-isolated; ensure input signals share a common ground reference with the rack to avoid ground loops.
-
Do not exceed 10 VDC on any input channel to prevent ADC saturation or damage.
-
Maintain ambient temperature and humidity within specified limits.
-
As this product is discontinued, handle as a critical spare part; verify functionality before installation.
