Foxboro E69F-T12-JRS – 12-Channel Relay Output Module for I/A Series DCS

In stock

Product Introduction:
The Foxboro E69F-T12-JRS is a 12-channel relay output module for the I/A Series distributed control system. The “E69F” identifies the relay output module family, “T12” specifies 12 output channels, and “JRS” denotes the jumper-configured revision S. This module provides 12 independent dry contact relay outputs that can switch AC or DC loads for controlling solenoid valves, motor starters, indicator lamps, and alarm annunciators. The relays are electromechanical with Form C (changeover) contacts, providing both normally open and normally closed contacts per channel. The “JRS” revision uses jumper-based configuration for contact rating and coil voltage, allowing the module to be customized for different load requirements without firmware changes.

Technical Specifications:
Board Type: Relay Output Module
System: Foxboro I/A Series DCS
Channels: 12 independent relay output channels
Contact Type: Form C (SPDT – Single Pole Double Throw)
Contact Rating: 5 Amps at 250V AC or 30V DC (resistive load)
Coil Voltage: 24V DC (jumper selectable: 12V, 24V, 48V, 120V AC)
Coil Power: Approximately 0.5 Watts per relay
Switching Time: Less than 10 milliseconds (energize), less than 5 milliseconds (de-energize)
Isolation: 500V RMS opto-isolated per channel
LED Indicators: Per-channel red LEDs show relay energized status
Communication: I/A Series UIM/LIM backplane
Power: 5V DC from backplane + 24V DC for relay coils
Form Factor: Eurocard (3U height)
Operating Temperature: 0 to 60 degrees Celsius

Functional Features:
12 Independent Relays: Each relay operates independently, allowing simultaneous control of 12 different field devices.
Form C Contacts: Each channel provides both NO and NC contacts, enabling complex control logic (e.g., energize one device while de-energizing another).
Jumper Configurable: Coil voltage and contact rating are set via jumpers, allowing field customization.
LED Status Indicators: Bright red LEDs on every channel show relay status without software.
Fail-Safe Operation: Relays default to de-energized (safe) state on loss of DCS communication.
Snubber Circuits: Built-in RC snubbers across each contact suppress arcing and extend relay life.
Hot Swappable: Can be removed and replaced while the system is running (in redundant configuration).

Application Scenarios:
Solenoid Valve Control: Switches 24V DC solenoid valves for process control in water treatment and chemical plants.
Motor Starter Control: Controls motor starter coils for pumps, fans, and compressors.
Alarm Annunciation: Drives alarm horns, strobe lights, and indicator lamps from the DCS.
Interlock Logic: Provides dry contact interlocks for safety systems (e.g., close valve A when pump B starts).
