621-9937 Honeywell Parallel I/O Module | 16 DI

Product Overview

The 621-9937 is a Honeywell Parallel I/O Module that provides 16 digital inputs (18-30 VDC) for the Honeywell IPC / ISSC 600 family. Plugging straight into the rack back-plane, it delivers:

Opto-isolated inputs - 2 kV channel-to-bus
LED status per channel - instant fault finding
Hot-swap - replace without powering down the rack
Parallel data transfer - < 1 ms update for high-speed interlocks

Ideal for CNC, packaging, power-gen and process skids that need fast, deterministic I/O expansion.
