Features:

  • Provides high or low process alarm detection with a relay output, eliminating external alarm trip amplifiers.
  • Prevents output chatter and allows stable control near the setpoint by configuring the reset point for the alarm.
  • Can be set as either latching (requiring reset) or non-latching (auto-reset), adapting to different safety or operational requirements.
The Honeywell 51196041-100 serves as a dedicated alarm limit amplifier within the UDC controller’s backplane. Instead of using an external standalone alarm trip device (which requires its own power supply, housing, and wiring), this module integrates directly. It monitors a process signal and compares it to a user-defined setpoint. When a high-limit or low-limit condition occurs, an internal SPDT relay changes state.

A common problem in limit monitoring is relay chatter. If the process variable fluctuates slightly around the setpoint, an alarm without hysteresis will turn on and off rapidly. This can damage relays and create nuisance alarms. The Honeywell 51196041-100 solves this with an adjustable deadband (hysteresis) potentiometer. The engineer sets a reset point that is different from the trip point. For example, on a high-limit alarm, the relay might trip at 200°C but reset at 190°C. This gap ensures stable, single-switching behavior.

Different applications require different alarm reset behaviors. In a safety application (e.g., a high-pressure interlock), the alarm should remain active after the fault condition clears until an operator manually acknowledges it. In a simple indication application (e.g., a tank level reaching full), the alarm should automatically reset when the level drops. The Honeywell 51196041-100 supports both via internal jumpers. In latching mode, once the alarm trips, the relay stays in the alarm state even if the process returns to normal.

The 3500/15 106M1079-01 Bently Nevada Universal AC Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

  • Large Power Plants: Networking critical control equipment such as boilers and turbines.
  • Pharmaceutical and Chemical Industries: Ensuring the stable transmission of highly sensitive monitoring data during production processes to the History Module.
  • Non-resistor Design: This T-connector is non-resistive, reducing signal attenuation and ensuring the full maintenance of 5 Mbps LCN network transmission rates.
  • High-Reliability Connection: Employs an industrial-grade BNC interface with an anti-loosening mechanism to withstand minor vibrations in industrial environments, preventing system alarms caused by momentary communication interruptions.
  • 8C Rating Conformal Protection: The surface features a conformal coating, maintaining good conductivity even in environments containing corrosive gases (such as hydrogen sulfide) or high humidity.
  • Node Expansion and Branching: When adding new Universal Stations or Network Interface Modules (NIMs) to an existing LCN coaxial cable bus, this T-connector provides redundant connections between rails A and B.
  • Network Maintenance and Spare Parts Replacement: As the TDC 3000 is a mature legacy system, this component is commonly used to replace connectors that have oxidized or aged due to long-term exposure to industrial environments, eliminating CRC errors or packet loss on the network.
Description
The Honeywell 51196041-100 monitors a process signal and activates an alarm relay when the measured value exceeds a setpoint or falls below it. It is essential for applications requiring overtemperature, overpressure, or level limit protection.

When using the Honeywell 51196041-100, engineers can configure the alarm as high or low acting. The module includes a Form C (SPDT) relay output, typically rated for 2A at 250VAC. It operates on 24V DC power and is designed for backplane mounting within the controller chassis.

The Honeywell 51196041-100 features an adjustable deadband (hysteresis) to prevent relay chatter when the process variable hovers near the setpoint. The alarm output can be latching or non-latching, depending on the configuration jumper settings. A front-panel LED indicates the alarm state.

For maintenance of legacy Honeywell UDC systems, the Honeywell 51196041-100 remains a critical spare part. It is obsolete for new designs but widely available through aftermarket suppliers. When replacing a failed module, ensure that the configuration jumpers match the original to maintain proper alarm behavior.

Technical notes
The Honeywell 51196041-100 alarm output can be configured as either latching (requires manual reset) or non-latching (automatically resets when process returns to normal). Jumper settings on the module select the mode.This module is designed to be field-replaceable and can be removed or inserted while the controller is powered off only. It is not hot-swappable.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the Honeywell 51196041-100 used for?
The Honeywell 51196041-100 is an alarm limit amplifier. It monitors a process variable (e.g., temperature, pressure) and activates a relay if the value exceeds a high setpoint or falls below a low setpoint, protecting equipment from unsafe conditions.
Is the Honeywell 51196041-100 compatible with my UDC controller?
The Honeywell 51196041-100 is designed for UDC 6000 and 6300 series controllers. Check your controller’s parts list. It occupies one backplane slot. For other Honeywell controllers (e.g., UDC 3200), a different alarm module is required.
Can I adjust the deadband on the Honeywell 51196041-100?
Yes. The Honeywell 51196041-100 features an adjustable deadband (hysteresis). This prevents relay chatter when the process variable fluctuates near the setpoint. Adjustment is made via a potentiometer on the module.
How do I know if the Honeywell 51196041-100 has triggered?
The Honeywell 51196041-100 has a front-panel LED indicator that lights when the alarm relay is active. For remote indication, the relay output can be wired to an external light or PLC input.
