Product Description

The F2-08TRS provides 8 independent, normally open (Form A) relay outputs. Unlike standard relay modules that share a common return, the “S” in the part number stands for Isolated, meaning each of the 8 points has its own isolated common. This allows the user to switch different voltages (e.g., 24V DC, 110V AC, and 220V AC) within the same module without electrical interference between channels.

Product Parameters

• Outputs per Module: 8 (Isolated).

• Output Type: Relay, Form A (SPST, normally open).

• Operating Voltage Range: 7–30V DC / 7–125V AC / 7–250V AC.

• Peak Voltage: 30V DC / 250V AC.

• Maximum Current (Resistive): 7A per point / 56A per module.

• Minimum Load: 10mA @ 12V DC.

• Response Time: * ON to OFF: 10 ms (max).

  • OFF to ON: 15 ms (max).

• Relay Life: 500,000 cycles (at 7A resistive load); 5,000,000 cycles (at 2A resistive load).

• Status Indicators: 8 LED indicators for logic-side status.

• Connector Type: Removable 19-position terminal block.

Product Advantages

• Point-to-Point Isolation: Every channel is electrically separated from the others, providing maximum flexibility for complex wiring schemes.

• High Current Capacity: With a 7A rating per point, it can drive larger solenoids, contactors, and small motors directly without needing interposing relays.

• Voltage Versatility: Can handle both AC and DC loads on the same module, which saves space and reduces the number of modules required in a system.

• Maintenance Friendly: The removable terminal block allows for fast module replacement without disturbing field wiring.

• Rugged Switching: Mechanical relays are highly resistant to voltage transients and electrical noise compared to solid-state outputs.

Precautions for Use

• Inductive Loads: When switching inductive loads (solenoids, motor starters, relays), always use external suppression like a flyback diode (for DC) or an RC snubber (for AC) to protect the relay contacts from arcing.

• Mechanical Life: Because these are mechanical relays, they have a finite lifespan. Avoid using them for high-speed “pulsing” applications like PWM (Pulse Width Modulation).

• Fusing: This module does not have internal fuses. It is highly recommended to install external fuses for each output to prevent damage to the module in the event of a short circuit.

• Hot-Swapping: Do not remove or insert the module into the PLC base while power is applied to the backplane or the field side.

Product Applications

• Motor Control: Switching 110V or 220V AC contactors for industrial pumps and fans.

• Lighting Systems: Controlling high-wattage lighting banks in warehouses or greenhouses.

• Diverse Voltage Switching: Useful in panels where some outputs are 24V DC (for sensors/indicators) and others are 120V AC (for valves).

• Heavy-Duty Solenoids: Driving large pneumatic or hydraulic valves that exceed the 0.5A or 2A limit of standard PLC modules.

• Alarm Circuits: Providing dry contact closures for building management systems or sirens.
