Deterministic EtherNet/IP Expansion Logic
The 1444-RELX00-04RB supports Profinet / EtherNet/IP deterministic networks for scalable relay output expansion. Each relay operates independently with defined voltage and current limits to maintain isolation and predictable protection behavior. Firmware compatibility ensures relay timing and sequencing remain consistent with connected 1444-DYN04-01RA modules, enabling synchronized machine protection across multiple monitoring nodes.
Frequently Asked Questions (FAQ)
Q: Can multiple relay expansion modules be connected to a single Dynamic Measurement Module?
A: Yes. Up to three 1444-RELX00-04RB modules can be connected to one 1444-DYN04-01RA module using the specified 1444-TB-B base and 1444-REL-RPC connector set.
Q: What is the maximum switching current for each relay?
A: Each SPDT relay supports up to 8 A, provided the supply voltage does not exceed 32 V DC.
Q: Are the relay modules suitable for harsh industrial environments?
A: Yes. The module is conformally coated and certified for shock, vibration, and compliance with IEC 60068 environmental standards.
Field Installation Guidelines
-
Mount the module on a 1444-TB-B terminal base and connect using the 1444-REL-RPC connector set.
-
Route relay wiring separately from analog signal and high-current power lines to minimize noise coupling.
-
Ensure DIN-35 rail is properly grounded and mechanically secure to prevent vibration-induced contact faults.
-
Verify all module bus connections to Dynamix 1444 controllers before applying power.
-
Observe environmental limits; avoid condensation and maintain ambient temperatures within -25 to +70 deg C.
