Woodward 8444-1063 MFR300 kW Transducers with Protection

The power supplies can only be installed into slots PS1 (power supply #1) and PS2 (power supply #2). If

redundant power supplies are not needed, blanking plates must be installed in the slots not being used.

Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having

jurisdiction for the specific country (CE, UL, etc.). See Table 4-3 for maximum recommended fuse or

breaker ratings. Do not connect more than one main power supply to any one fuse or circuit breaker. Use

only the wire sizes specified in Table 4-3. which meet local code requirements.

Time delay fuses or circuit breakers must be used to prevent nuisance trips.

Module Operation 

For redundant systems, up to two Remote RTN modules may be installed into each MicroNet Plus 8/14 

slot expansion chassis (only one RTN can be installed in the MicroNet 6/12 slot chassis). When initialized 

by the main chassis CPU, the Remote RTN modules will acquire either a SYSCON or STANDBY status. 

The Remote RTN module that becomes SYSCON will control the expansion chassis it is located in. It will 

synchronize with the STANDBY Remote RTN module and perform any redundancy functions as 

necessary. Input and output data from all I/O modules will be managed appropriately and made available 

to the GAP Application running in the main-chassis CPUs. 

The Remote RTN module communicates with the I/O modules in the expansion chassis and also the CPU 

modules in the main chassis. When the power is applied, the Remote RTN module will perform diagnostic 

tests before beginning communications. 

RTN Expansion Chassis Configurations 

The MicroNet TMR5200 can expand from a single main rack to a maximum 4-rack system by using Remote 

RTN modules and copper or fiber optic Ethernet switches. A maximum of 3 MicroNet Plus expansion racks (14 

slot or 8 slot versions) or MicroNet Simplex racks (6 or 12 slot versions) are supported. If desired, fiber optic 

Ethernet switches can be used to locate each chassis in a different location. It is required to use Woodward 

approved Ethernet hardware for robust operation.
