In industrial environments where gas monitoring is critical, having a reliable and versatile system in place is paramount. The B14 Gas Alarm Module Receivers are designed to meet these demands, offering robust performance and flexibility. These modules accept input from two, three, or four-wire 4-20mA transmitters located up to 10,000 feet away, providing comprehensive local alarm, display, and retransmission functions. Whether you need to monitor gases in multiple rooms from a single remote location or integrate with a variety of gas monitors, the B14 is an ideal solution.
Key Features of the B14
LED Display and Monitoring
- Comprehensive Display: Gas concentrations are displayed in parts per million (PPM), parts per billion (PPB), percent, or percent lower explosive limit (LEL), configurable at the time of ordering.
- Multiple Gas Compatibility: The B14 is compatible with 38 different gases, making it a versatile choice for various applications.
Advanced Alarm System
- Three Alarm Setpoints: Each module features separate caution, warning, and alarm setpoints with LED bar indicators. The LEDs flash initially upon alarm activation and then change to steady once the alarm condition is acknowledged.
- Relay Outputs: Equipped with three individual alarm relays per module, these relays can be assigned to any setpoint, allowing for multiple alarm functions at a single point. They can be configured for standard or fail-safe operation, as well as latching or non-latching operation.
- Trouble Alarm: An additional fourth LED alarm bar and relay indicate trouble conditions, such as loss of input signal or if the 4-20mA input drops below a specific value.
Remote and Internal Control
- Remote Reset Input: Provides isolated input contacts for acknowledging alarm conditions from a remote location or via telemetry equipment.
- Internal Transmitter Power: Supplies 24 VDC to operate two or three-wire transmitters, simplifying power management.
Signal Retransmission and Power
- Signal Retransmission: Each module provides a 4-20mA output, optically isolated from the input signal to prevent ground fault issues.
- DC Powered: The B14 modules operate on a 12 VDC power supply, which can power up to three modules (or two with battery backup). User-provided 12-28 VDC supplies are also compatible.
Customization and Ordering
The B14 modules are highly customizable to meet specific requirements. Here’s how you can tailor your order:
Alarm Measurement Range
Specify the gases and ranges you need displayed. Each module is custom set, so a variety of gases and ranges can be accommodated.
Enclosure Options
The B14 comes in various enclosure sizes based on the number of receivers and power supplies required, all made from NEMA 4X material with standard 35mm DIN rail mounting:
- Single Module: Houses a single receiver module for DC power applications.
