4‑channel relay output module with independent common for CONPROSYS nano. The CPSN‑RRY‑4PCA features Form A relays rated at 2A 30VDC / 0.5A 125VAC, bus isolation, LED status indicators, and long mechanical life (100 million operations). Wide temperature range (-20 to +60°C) and tool‑less installation. From Contec Americas.
The CPSN‑RRY‑4PCA is an expansion I/O module for the CONPROSYS nano series, adding 4 channels of independent common Form A relay outputs. Each channel has its own common terminal, allowing different external power supplies per channel. The relays are rated for 2A 30VDC or 0.5A 125VAC, making them suitable for switching a wide range of loads. LED indicators provide visual confirmation of relay status.
Independent common – each channel has its own common terminal, enabling different voltages or circuits to be switched independently. This provides maximum flexibility for industrial control applications.
Designed for demanding factory automation, machine control, and process control applications. The CPSN‑RRY‑4PCA operates across a wide temperature range (-20 to +60°C) and features bus isolation via relays for excellent noise immunity. The module installs and removes without tools, simplifying system maintenance.
