• Relative Humidity: 5% ~ 95% non-condensing

  Functional Features:

• Each channel relay electrical isolation
• LED indication for each output channel status
• Built-in freewheeling diode for inductive load
• Relay coil surge suppression
• Hot-swappable design
• Output state feedback diagnosis

  Performance Parameters:

• Isolation Voltage: 1500 VAC coil to contact
• Contact On-resistance: ≤ 50 mΩ
• Bus Communication Rate: 1 Mbps

  Material Composition:

• Casing: Flame-retardant industrial ABS
• PCB: FR-4 high-strength circuit board
• Relay: Industrial grade power relay with silver alloy contacts
• Internal Insulation Parts: High-temperature resistant engineering plastic

  Structural Characteristics:

• 3U standard rack-mount size
• Front panel dense LED indicator area
• Rear backplane bus connector
• Independent partition for each relay to avoid mutual interference

  Working Principle:

  The DCS controller sends on/off control commands to the module via backplane bus. The internal drive circuit energizes or de-energizes relay coils to control the closing and opening of relay contacts. The contacts directly control the power loop of field motors, solenoid valves and contactors to complete switch control.

  Advantages & Highlights:

• Mechanical contact isolation realizes strong and weak current complete isolation
• Large contact load capacity drives high-power field equipment directly
• Long mechanical service life for frequent switching loops
• Built-in surge protection adapts to inductive load working condition

  Applicable Industries: Power plant auxiliary equipment control, chemical valve interlock, metallurgical motor control, industrial fan and pump control

  Model Series: Emerson Ovation Relay Output Module Series

  Installation Requirements:

• Install on DCS standard rack vertically
• Strong current output wiring uses thick wire in accordance with load current
• Inductive load must connect absorption components in parallel
• Keep ventilation to reduce relay operating temperature

  Usage Notes:

• Never exceed contact rated voltage and current load
• Check contact ablation regularly under frequent switching
• Cut off external strong current power before module replacement
• Avoid long-term overload of relay contacts
