Configured for digital signal acquisition in industrial automation networks, the YOKOGAWA A2SDV105-S000 (A2SDV105-S000) Digital Input Adapter Module provides direct physical and electrical execution for N-IO platform architectures.

Hardware Specifications

Channel Isolation and N-IO Bus Architecture

The module incorporates robust optical and galvanic isolation circuitry rated at 3000 V AC between input and output, alongside 1500 V AC isolation to ground, eliminating ground loops and high-voltage transients across multi-loop environments. Signal conditioning stages process digital inputs with an update response time up to 22 ms, ensuring stable and reliable signal processing. Internal N-ESB Bus communication interfaces maintain high-speed, deterministic data exchange across up to six connected I/O units within the node assembly.

Frequently Asked Questions

Q: What is the maximum current consumption of the A2SDV105-S000 module from the internal power supply?

A: The module draws a maximum of 14 mA from the internal 5 VDC supply bus during operation.

Q: How many I/O units can be connected to this adapter module in an N-IO system setup?

A: The module supports expansion for up to six connected I/O units.

Field Installation Guidelines

Mount the A2SDV105-S000 adapter module securely onto a DIN rail or wall-mounted A2BN3D base plate, ensuring complete backplane connector engagement. Terminate external alarm and digital input wiring carefully, observing voltage thresholds between 18 and 26.4 VDC for ON states and 5 VDC or lower for OFF states. Verify supply voltage limits and confirm isolation ratings prior to system energization.
