5X00489G01 high-reliability digital input module

5X00489G01 is a high-reliability digital input module developed by Emerson for its Ovation Distributed Control System (DCS). It specializes in collecting discrete digital signals from industrial field devices (such as limit switches, proximity sensors, and relay contacts) and transmitting them to the Ovation DCS for real-time status monitoring and logic interlock control, ensuring stable operation of critical industrial processes. Below is its detailed information:

1. Core Technical Specifications

Parameter Category	Specific Details
Input Channels	16 independent discrete input channels, divided into 4 isolation groups (4 channels per group) to eliminate cross-interference between signals from different field devices.
Supported Input Signals	- Dry contact signals: Compatible with normally open (NO) / normally closed (NC) mechanical switches (e.g., safety door locks, pump status contacts).- DC voltage signals: 24V DC (typical), with "on" threshold ≥18V DC and "off" threshold ≤5V DC, adapting to mainstream industrial discrete signal standards.
Input Response Time	≤1ms (fast enough to capture transient signals like emergency stop triggers, ensuring the DCS responds promptly to critical status changes).
Input Current	≤10mA per channel (low power consumption, avoiding overload of field sensors and reducing energy waste in the control system).
Power Supply	24V DC ±10% (power consumption ≤5W), fully compatible with Ovation DCS rack power modules (e.g., 1C31234G01), adapting to voltage fluctuations in industrial power grids.
Isolation Rating	- Group-to-group isolation: ≥600V AC (1 minute).- Module-to-backplane isolation: ≥2500V AC (1 minute), effectively suppressing ground loops and electromagnetic interference (EMI) in complex industrial environments.
