Wide Voltage Compatibility
Supports a broad input range (24 VAC to 250 VAC / 300 VDC), enabling use across diverse field environments with a single module type.
High-Level Isolation
Each channel is electrically isolated to protect control systems from voltage transients and ground faults.
Fast Response Time
Sub-millisecond response enables accurate sequence-of-events (SOE) capture and fast interlocking applications.
Noise Immunity & Signal Stability
Internal filtering reduces contact bounce and electrical noise, ensuring reliable state detection.
Monitoring of limit switches and motor auxiliary contacts
Sequence-of-events (SOE) recording systems
High-voltage discrete signal acquisition
Power generation, oil & gas, and chemical processing plants
Safety interlocking and control systems
Does it support redundancy?
Yes, it supports redundant configurations with automatic failover.
Is it suitable for SOE applications?
Yes, its fast response time makes it ideal for precise event timing and logging.
Can it be hot-swapped?
Yes, it can be replaced without shutting down the system.
What type of IOTA is required?
It requires a dedicated high-voltage digital input IOTA designed for appropriate voltage isolation and clearance.
