Product Description:
Product code 084B4184 is a top-performance module of Danfoss company. This AK-CC55 Multi Coil controller clarifies the device for multi-evaporator refrigeration control. Weighing 0.317 kg, it reduces panel loading and simplifies handling during assembly and service. With 7 analog inputs, it permits simultaneous monitoring of multiple sensors and supports coordinated valve and pressure control. Single analog output provides one control signal for valve or actuator modulation which centralizes analog control.
The two digital inputs allow discrete event sensing for functions such as defrost or alarm acknowledgement which simplifies wiring logic. In addition, the seven digital outputs enable multiple relay or transistor-driven actions that support independent control of fans and heaters. Further, the communication built-in MODBUS supplies a standard protocol for system integration which eases connection to facility controllers. Also, communication card option LON RS485 offers an alternative fieldbus interface, allowing an integration with LonWorks networks. The unit’s voltage range of 115-230 V AC> covers common supply voltages which reduces the demand for external transformers.
Its frequency <<50/60 Hz guarantees compatibility with both regional mains frequencies which supports global deployment. 084B4184 lists power consumption 5 VA which limits control power draw and helps size the control transformer or supply. Number of evaporators max. 3 pc defines the maximum evaporator count supported which directs system topology choices. Its DIN rail mounting allows standardized enclosure installation to assist fast field replacement. Having a press. transmitter support RATIOMETRIC supplies compatibility with common pressure sensors and simplifies sensor selection. Also, the packing format industrial pack identifies supply unit packaging which informs procurement and storage planning.
Frequently Asked Questions about 084B4184:
Q: How many analog inputs do 084B4184 provide?
A: The seven analog inputs support multiple temperature and pressure transducers for control and monitoring. Systems allocate 7 inputs for sensor redundancy and control loop segregation.
Q: What analog output capability does 084B4184 include?
A: With analog output as 1 supplies a proportional control signal for valves or actuators. Control schemes route the analog output to the primary modulation device.
Q: How many digital inputs are available on 084B4184?
A: Offering 2 digital inputs accept discrete signals for events like defrost or safety interlocks. Wiring schematics allocate DI1 and DI2 to prioritized control actions.
Q: What communication protocol is built into 084B4184?
A: The device’s communication built-in protocol is MODBUS. This protocol provides a widely supported interface for supervisory systems and data exchange. Integration and polling use MODBUS registers and addressing.
Q: How many digital outputs do 084B4184 variant offer?
A: These seven digital outputs drive relays or transistor loads for fans, lights, or alarms.
