Product Introduction

Model Interpretation

• 45C = Family code for Reliance Electric Shark XL series I/O modules.

• 994 = Analog output module; “9” = special function I/O, “94” = 2‑channel, 0–10 VDC output type.

• No suffix = standard revision; compatible with all Shark XL racks.

Technical Parameters

• Channels: 2 single‑ended analog outputs.

• Output range: 0–10 VDC (voltage only).

• Resolution: 8 bits (256 steps, ~39 mV per step).

• Output impedance: 100 Ω per channel.

• Conversion time: 1 ms per channel.

• Isolation: No galvanic isolation between field and logic; no channel‑to‑channel isolation.

• Indicators: Power OK LED, module fault LED.

• Operating temperature: ‑20 °C to +60 °C.

• Storage temperature: ‑40 °C to +85 °C.

• Humidity: 0–95% RH, non‑condensing.

• Protection class: IP20 (cabinet mounting).

• Mounting: Shark XL / 45C‑series DIN rail.

• Certification: UL, CE, CSA.

• Power consumption: ~25 mA @ 5 VDC (backplane).

Interface and Communication Configuration

• Backplane connection: Plug‑in to Shark XL rack backplane for power and data exchange.

• Field wiring: Front‑panel screw terminals for 2 analog outputs (0–10 VDC) and common ground.

• Communication: Backplane bus only; no external serial/network ports.

• Compatibility: Shark XL PLC systems; 45C‑series I/O rail (up to 8 modules per rail).

Core Functions

• Converts PLC digital values to 0–10 VDC analog signals for proportional control.

• 2‑channel independent output for dual‑actuator applications.

• Fast 1 ms conversion time for real‑time control response.

• LED status enables quick verification of power and module health.

• Compact design integrates seamlessly with Shark XL racks for centralized I/O control.

Application Scenarios

• Process control: Driving proportional valves, motor speed controllers, and analog displays.

• Manufacturing: Controlling actuators in assembly lines, packaging, and material handling.

• HVAC: Adjusting dampers and valves in building automation systems.

• Water/wastewater: Regulating flow and pressure via analog control signals.

Operation and Maintenance Instructions

• Install on a Shark XL DIN rail and ensure full backplane engagement before powering on.

• Wire 0–10 VDC analog outputs to front‑panel terminals; observe polarity and common ground.

• Verify load impedance is ≥ 1 kΩ to prevent output overload.

• During operation, monitor LEDs: Power OK ON, fault LED OFF for normal status.

• Keep the module clean and well‑ventilated to prevent overheating.

• Disconnect system power before removal, inspection, or replacement.

• Do not disassemble internal components; replace the entire module if a permanent fault occurs.

• The unit is discontinued by Reliance Electric; use surplus or refurbished units for replacement.
