Functional Description

5441-413 is a Relay Interface Module developed by Woodward. It is a 32 Channel Relay Interface Module, used to control electrical loads by providing a means to switch them on or off. It typically consists of multiple relays arranged in a module, along with necessary circuitry and connectors for interfacing with other systems. It act as an interface between a control system, such as a microcontroller or a programmable logic controller (PLC), and the loads that need to be controlled. Each channel of the module corresponds to a separate relay, allowing independent control of multiple electrical devices.

Features

• The module usually has input terminals that connect to the control system, and output terminals to which the electrical loads are connected. The control signals from the control system activate the relays, which then switch the corresponding loads on or off. Depending on the module, each relay may be capable of handling different voltages and currents, allowing for control of various types of loads.
• The 16-channel relay interface modules are only suitable for non-hazardous or ordinary locations.
• The eighteen-slot MicroNet TMR control chassis is composed of three blocks with a motherboard inserted in the back of the assembly to make connections between the fans, switches, power supply chassis, and all three kernels. The modules use the VERSAmodule Eurocard (VME) bus standard for connector specification and data transfer. Kernel-to-kernel and slot-to-slot logic and power connections are made through an etched-circuit motherboard. I/O connections are made through cables from the front of the boards to field termination modules in the cabinet.

Characteristics

• Allows to control multiple relays or switches through digital signals from a control system, such as a programmable logic controller (PLC) or a microcontroller. It provides the necessary circuitry to drive the relays and switch them on or off based on the control signals received.
• Offers multiple input and output channels. The input channels receive digital control signals from the control system, while the output channels drive the relays or switches. The number of channels can vary depending on the specific CRIM model.
• Ensure proper electrical isolation between the control system and the external devices, CRIMs often incorporate isolation circuitry. This isolation protects the control system from electrical noise, voltage spikes, and other disturbances that may occur in the external environment.
• Support various communication protocols to interface with the control system. Common protocols include Modbus, Profibus, Ethernet/IP, CANbus, and others. The choice of protocol depends on the requirements of the specific application and the compatibility with the control system.

Frequently Asked Questions

What is 5441-413?
It is a Field Terminal Module developed by Woodward.

Can the relays in the module handle different voltages and currents?
Yes, the relays in the module can be designed to handle different voltages and currents, allowing for control of various types of loads with different electrical requirements.

What is the purpose of the VERSAmodule Eurocard (VME) bus standard in the control chassis?
The modules in the MicroNet TMR control chassis use the VERSAmodule Eurocard (VME) bus standard for connector specification and data transfer. This standard ensures compatibility and facilitates communication between the modules.

How are logic, power, and I/O connections established within the control chassis?
Logic and power connections between kernels and slots are made through an etched-circuit motherboard. I/O connections are established by running cables from the front of the boards to field termination modules (FTMs) in the cabinet, which act as interfaces between the control system and field devices or sensors.
