30754999-502

The control output PCB identified by part number 30754999-502, part of Honeywell's DR4500 series, is built for versatility and performance in demanding applications. It is specifically designed for use with both Truline and Classic Series circular chart recorders, making it suitable for diverse sectors including thermal processing, HTST in food and dairy, and water-treatment facilities. Its capacity to handle 1 to 4 analog inputs allows for flexible operational configurations.

Equipped with two independent PID loop controllers, this PCB supports complex control logic essential for precise temperature and flow management in environments such as metals heat treating and environmental testing chambers. Included are dual EPROM sockets that accommodate memory expansion, alongside a 3V coin-cell lithium battery that provides reliable backup for retained settings and configurations.

With auxiliary power requirements between 22 to 26 volts DC, this PCB is quick to integrate into existing systems. The multi-pin ribbon connectors and terminal headers facilitate easy connectivity and expansion capabilities. For advanced applications, optional RS-485 Modbus RTU communication can be implemented through an auxiliary module, enhancing its networking capability for integrated system solutions. Furthermore, the unit's construction from multi-layered FR-4 glass-reinforced epoxy ensures its longevity, complemented by a conformal coating that protects against environmental factors. This part operates within a relative humidity range of 10% to 90% without condensation, ensuring performance stability in various operational conditions.
