The 05704-A-0145 is a four-channel control card manufactured by Honeywell, primarily used in industrial automation, DCS, and gas detection systems. It features high-performance processing capabilities, enabling real-time acquisition, processing, and monitoring of signals from multiple industrial sensors.
Processes the incoming sensor signals
Informs other cards with the alarm status information
Compares each channel signal level with pre-defined alarm limits
The 5704 Four Channel Control Card provides control, display and alarm facilities for up to four connected gas detectors. The front panel backlit display indicates the gas reading, channel status and channel number while LEDs are used for alarms. A push-button is provided for resetting the alarms and selecting the card for use with the Engineering Card. The operation of the control card is microprocessor controlled and is fully definable for a wide range of connected gas detectors and application requirements. The software configuration setup is stored in an EEPROM.

Oil & Gas
Monitoring methane (CH4) and other flammable gas leaks on drilling platforms to prevent fire and explosion.
Chemical Plants
Detecting toxic gas concentrations (such as H2S) to protect employees from poisoning.
Steel & Metallurgy
Monitoring carbon monoxide (CO) around furnaces to prevent personnel poisoning.
Rail Transport
Gas monitoring in battery charging rooms or specific transport vehicles.
Water & Wastewater
Monitoring methane and hydrogen sulfide in confined spaces to prevent biogas buildup.
Logistics & Warehousing
Monitoring hazardous gas concentrations in chemical storage facilities.
Ensure that the card configuration perfectly matches the connected detector type (e.g., Catalytic Bead or Infrared) and regularly verify alarm thresholds and zero points using the Engineering Card. During installation, inspect the rack backplane pins carefully to avoid damaging EEPROM data caused by forceful hot-swapping. Meanwhile, maintain adequate ventilation within the control cabinet to prevent heat buildup from high-density card arrangements, which could compromise sensor power stability and module lifespan.
It is a control card for the Honeywell System 57, specifically designed to monitor flammable gases (%LEL).
What is the primary function of the 05704-A-0145?
It receives detector signals, displays gas concentrations, and triggers relays when preset alarm levels are reached.
How to install the 05704-A-0145?
It is installed by plugging it into a standard System 57 rack.
How many alarm levels does the 05704-A-0145 have?
It typically offers two or three configurable alarm levels (A1, A2, A3).
How to perform a zero calibration on the 05704-A-0145?
Use the front panel control buttons to enter the menu and perform a Zero adjustment.
