Features:
- Four-Channel Control Card (4-20mA Input)
- Card depending on the type of gas detector being fitted to the system
- The four-channel control card can control up to four gas detection loops
The 5704 four-channel control card provides control, display, and alarm functions for up to four connected gas detectors. A backlit front panel display shows gas readings, channel status, and channel number, while LED indicators show alarm status. Alarms can be reset via buttons, and the control card can also be used with engineering cards.
This microprocessor-controlled control card can be fully customized to various connected gas detectors and application requirements. Software configuration settings are stored in EEPROM. Optional analog output modules can be inserted into the four-channel control card for remote output of channel card readings. One module is required per channel, and different types of modules are provided, which can be used as current sources or current absorbers as needed.
The 05704-A-0144 Honeywell Four Channel Control Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Provides the voltage and current required to drive connected sensors. Processes input sensor signals. Displays signal levels one by one on the front panel LCD. Compares the signal level of each channel with predefined alarm limits. When a preset alarm limit is exceeded, an alarm is triggered: the front panel LED indicator illuminates and the connected relay operates. Sends alarm status information to other cards. Self-tests the operation of circuit components, software, and sensor status.
Combustible Gas Detection: Designed for connection with catalytic bridge sensors to monitor the Low Explosive Level (LEL) of gases such as methane, propane, and hydrogen.
High-Density Safety Monitoring: Utilizes a System 57 rack, providing up to 64 monitoring channels within a standard 19-inch footprint, ideal for large industrial facilities.
Industrial Safety Systems: Commonly used in high-explosion-risk locations such as oil and gas refineries, petrochemical plants, and wastewater treatment plants.
Automatic Alarm Triggering: Processes sensor data to drive local visual/audible alarms and connects to Honeywell relay cards to trigger emergency shutdowns or ventilation systems.
