S-073N 3BHB009884R0021- ABB 32 channel digital input module (AC800M/800xA series)
=========Product identity=========
Brand: ABB (Sweden)
Model: S-073N
Order number: 3BHB009884R0021
Type: Digital Input Module (DI Module)
System: ABB AC 800M/Advant Controller 100/800xA DCS
ABB S-073N 3BHB009884R0021
[Core positioning]
This is a 32 channel digital input module in the AC 800M distributed control system, used to collect 24VDC dry contact or level signals on site. It is the “state perception nerve” of the DCS system – each motor start stop and each valve limit rely on it to collect feedback to the controller.
=========Electrical parameters=========
Number of input channels: 32 channels (divided into 4 groups, each with 8 channels)
Input signal type: 24VDC (compatible with dry contacts, NPN/PNP transistor output)
Rated input voltage: 24VDC (allowable range: 18-30VDC)
Input current: approximately 3.5mA @ 24VDC
Response time: Typical value<1ms (software configurable filtering: 0/3/10ms)
Electrical isolation: 500VAC RMS (between channel group and backplane)
MTBF (Mean Time Between Failures):>150000 hours
=========Mechanical and environmental parameters=========
Working temperature: 0 ° C to+60 ° C
Protection level: IP20 (to be installed inside the control cabinet)
Installation method: Insert into the AC 800M I/O rack (occupying 1 slot), and a dedicated terminal base (such as TB820) is required
Hot swappable: supported (when system configuration allows)
Certification: CE, UL 61010-1, IEC 61326-1
=========Status indication=========
Green LED for each channel: on=ON, off=OFF
